Last, Electronics, MDPI AG, 12, 6, 1335-1335, 11 Mar. 2023, Peer-reviwed, Internet of Vehicles (IoV) is a network that connects vehicles and everything. IoV shares traffic data by connecting vehicles with the surrounding environment, which brings huge potential to people’s life. However, a large number of connections and data sharing will seriously consume vehicle resources during the interaction. In addition, how to build a safe and reliable connection to ensure vehicle safety is also an issue to consider. To solve the above problems, researchers introduce blockchains into IoV to build a safe and reliable vehicle network relying on the distributed account structure, immutable, transparent and security features of blockchains. We have investigated the application of blockchains in IoV in recent years, and have summarized and compared these studies according to their purposes. On this basis, we also point out the future trends and opportunities.

Sensors (Basel, Switzerland), 22, 18, 6995-6995, 15 Sep. 2022, Peer-reviwed, True, Internet of Vehicles (IoV) technology has been attracting great interest from both academia and industry due to its huge potential impact on improving driving experiences and enabling better transportation systems. While a large number of interesting IoV applications are expected, it is more challenging to design an efficient IoV system compared with conventional Internet of Things (IoT) applications due to the mobility of vehicles and complex road conditions. We discuss existing studies about enabling collaborative intelligence in IoV systems by focusing on collaborative communications, collaborative computing, and collaborative machine learning approaches. Based on comparison and discussion about the advantages and disadvantages of recent studies, we point out open research issues and future research directions.

Sensors (Basel, Switzerland), 21, 8, 2793-2793, 15 Apr. 2021, Peer-reviwed, True, Multipath TCP (MPTCP) is one of the most important extensions to TCP that enables the use of multiple paths in data transmissions for a TCP connection. In MPTCP, the end hosts transmit data across a number of TCP subflows simultaneously on one connection. MPTCP can sufficiently utilize the bandwidth resources to improve the transmission efficiency while providing TCP fairness to other TCP connections. Meanwhile, it also offers resilience due to multipath data transfers. MPTCP attracts tremendous attention from the academic and industry field due to the explosive data growth in recent times and limited network bandwidth for each single available communication interface. The vehicular Internet-of-Things systems, such as cooperative autonomous driving, require reliable high speed data transmission and robustness. MPTCP could be a promising approach to solve these challenges. In this paper, we first conduct a brief survey of existing MPTCP studies and give a brief overview to multipath routing. Then we discuss the significance technical challenges in applying MPTCP for vehicular networks and point out future research directions.

Sensors (Basel, Switzerland), 21, 3, 716-716, 21 Jan. 2021, Peer-reviwed, True, Cooperative communication and resource limitation are two main characteristics of mobile ad hoc networks (MANETs). On one hand, communication among the nodes in MANETs highly depends on the cooperation among nodes because of the limited transmission range of the nodes, and multi-hop communications are needed in most cases. On the other hand, every node in MANETs has stringent resource constraints on computations, communications, memory, and energy. These two characteristics lead to the existence of selfish nodes in MANETs, which affects the network performance in various aspects. In this paper, we quantitatively investigate the impacts of node selfishness caused by energy depletion in MANETs in terms of packet loss rate, round-trip delay, and throughput. We conducted extensive measurements on a proper simulation platform incorporating an OMNeT++ and INET Framework. Our experimental results quantitatively indicate the impact of node selfishness on the network performance in MANETs. The results also imply that it is important to evaluate the impact of node selfishness by jointly considering selfish nodes' mobility models, densities, proportions, and combinations.

Sensors (Basel, Switzerland), 20, 18, 1-37, 07 Sep. 2020, Peer-reviwed, True, The vehicular Internet of Things (IoT) comprises enabling technologies for a large number of important applications including collaborative autonomous driving and advanced transportation systems. Due to the mobility of vehicles, strict application requirements, and limited communication resources, the conventional centralized control fails to provide sufficient quality of service for connected vehicles, so a decentralized approach is required in the vicinity to satisfy the requirements of delay-sensitive and mission-critical applications. A decentralized system is also more resistant to the single point of failure problem and malicious attacks. Blockchain technology has been attracting great interest due to its capability of achieving a decentralized, transparent, and tamper-resistant system. There are many studies focusing on the use of blockchain in managing data and transactions in vehicular environments. However, the application of blockchain in vehicular environments also faces some technical challenges. In this paper, we first explain the fundamentals of blockchain and vehicular IoT. Then, we conduct a literature review on the existing research efforts of the blockchain for vehicular IoT by discussing the research problems and technical issues. After that, we point out some future research issues considering the characteristics of both blockchain and vehicular IoT.

Japanese - Resolving Bufferbloat Problem at Access Point for Upload TCP Communication Over IEEE802.11n Wireless LAN
Masataka Nomoto; Celimuge Wu; Satoshi Ohzahata; Toshihiko Kato
情報処理学会論文誌, IPSJ, 58, 2, 427-438, 01 Feb. 2017, Peer-reviwed, IEEE 802.11n無線アクセスポイントを経由するTCP通信では，低いMACレベルデータレートが使用される場合に，往復遅延が増加するBufferbloat問題が発生し，同じキューを共通する他の通信の遅延時間が増加し，ユーザレベルの品質の悪化となる．この対処として，アクティブキュー管理方式，筆者らが先に示した無線LANの最大再送回数を制限する方法，遅延増加時にTCP通信を停止する方法などが提案されている．しかしこれらはすべて，データの送信側に実装する必要がある．このため，端末からアクセスポイントへのアップロード転送においては，端末のすべてにこのような方式を導入しなければならない．そこで本稿では，データの受信側であるアクセスポイントにおいて，低いMACレベルデータレートで無線LANフレームの最大再送回数を制限したと同様な効果を与えることにより，TCPの輻輳ウィンドウを減少させ，Bufferbloat問題に対応する方法を提案する．パソコンを用いたアクセスポイントに提案方式を実装することにより，Bufferbloat問題に対応していない端末で，低いMACレベルデータレートでの往復遅延を減少させられること，さらにBufferbloat問題に対する方法を実装している端末においてもTCP通信のスループットを悪化させることがないことを明らかにした．IEEE 802.11n wireless LANs provides a Bufferbloat problem such that the round-tirp delay increases in TCP communications when the MAC level data is low such as 6.5Mbps. This problem degrades user level quality of service for communications sharing the transmission queue with the TCP communications. In order to resolve this problem, several schemes are proposed such as a scheme based on active queue management, our previous scheme reducing the retry-out limit at low data rate, and a scheme stopping sending TCP level data when the queue contains more than a specific number of packes. However, those schemes need to be implemented at the sender side. In this paper, we propose a new scheme resolving a Bufferbloat problem in the upload TCP communications by providing an effect at a receiving side access point similar to reducing the retry-out limit when the MAC level data rate is low. This decreases the congestion window size in the sending side and can reduce the delay. This paper also shows the results of the performance evaluation by implementing the proposed method in a PC based access point. According to the results, the proposed method decreases the round-trip time in the low MAC data rate and does not reduce the TCP throughput. It does not give any influences on the TCP thoughput for the terminals supporting the conventional schemes for Bufferbroat problems.

IEICE Technical Report, The Institute of Electronics, Information and Communication Engineers, 114, 160, 75-80, Jul. 2014, In this paper, we propose a broadcast protocol for vehicular ad hoc networks. The protocol can reduce the MAC layer contention time by using backbone-based forwarding. Network coding is used to attain high reliability with low overhead. Therefore, the protocol is able to provide a lightweight and reliable solution for data dissemination in VANETs. We use theoretical analysis and computer simulations to show the advantage of the proposed protocol over other existing alternatives.

IEICE Technical Report, The Institute of Electronics, Information and Communication Engineers, 114, 110, 1-6, Jun. 2014, Designing an effcient unicast routing protocol for vehicular ad hoe networks has been a challenging issue due to the vehicle movement, limited wireless resources and lossy feature of wireless channel. We propose a protocol which utilizes inter-flow network coding to route data messages. The proposed protocol uses common backbone vehicles for different traffic flows. A reliability connected backbone is selected by considering vehicle movement dynamics and link quality between vehicles. By using inter-flow network coding at the backbone vehicles, the protocol can reduce the number of generated packets by 25% in most cases as compared to the traditional routing approach. As a result, the proposed protocol can provide a high packet delivery ratio, low overhead and low delay. We show the effectiveness of the protocol using computer simulations.

Information and Media Technologies, Information and Media Technologies Editorial Board, 5, 2, 798-812, 2010, Many safety applications in Vehicular Ad hoc Networks (VANETs) are based on broadcast. Designing a broadcast protocol that satisfies VANET applications' requirements is very crucial. In this paper, we propose a reliable and efficient multi-hop broadcast routing protocol for VANETs. The proposed protocol provides the strict reliability in various traffic conditions. This protocol also performs low overhead by means of reducing rebroadcast redundancy in a high-density network environment. We also propose an enhanced multipoint relay (MPR) selection algorithm that considers vehicles' mobility and then use it for relay node selection. We show the performance analysis of the proposed protocol by simulation with ns-2 in different conditions, and give the simulation results demonstrating effectiveness of the proposed protocol compared with other VANET broadcast schemes.

Cloud computing has been proved that it can reduce hardware cost and improve performance in Internet environment. There are some attempts in building cloud computing frameworks in vehicular environment. However, most frameworks proposed by now are centralized, which means they rely on the deployment of infrastructures which are not quite common right now. In this paper, we present a new framework for vehicular cloud computing. In this framework, we utilize the idle resource of vehicles on the road to provide cheap and neighbor services to each other. We also present an distributed and autonomous routing protocol for the service requests, with overhearing technique and forwarder selecting metric, aiming at reducing flooding packets on the network and balancing the workload.

Cloud computing is one of those services that can boost the information processing performance of vehicles without raising the cost on hardware, and support various other services in vehicular environment. There are already some attempts in building cloud computing frameworks in vehicular environment.

WEI Jing; LI Jinglin; LIU Zhihan; WU Celimuge; OHZAHATA Satoshi; KATO Toshihiko
We propose a common service platform for electric vehicles (EVs). The platform is supposed to make use of information of EVs, EVs users, traffic flow, map and charging network to provide common service such as GIS service, resource management service, billing service, and open API service for EVs users, charging service operators and service developers. We divide the platform into three layers, which are resource layer, capability layer and service layer. Resource layer is to store data, and provide data access interface to capability layer. Capability layer encapsulates some common function, and provides the function to service layer. Meanwhile, capability layer will authorize and authenticate the invoking services. Service layer provides common service for platform users. Service developers can use open API of capability layer to organize new customized service. We describe our demo implementation of the proposed platform framework., The Institute of Electronics, Information and Communication Engineers, 22 Jan. 2015, Technical report of IEICE.

Wang Weikai; WU Celimuge; OHZAHATA Satoshi; KATO Toshihiko
Recently, packet losses can be caused by transmission interruptions such as handoffs in the mobile networks and protection switching in the transport networks. These packet losses are bursty because the transmission interruptions continue for tens of miliseconds through several seconds. Previously, we performed the experimental analysis for various TCP versions running on Linux and MAC OS, and found that, although TCPs in Linux recover from bursty losses quickly, TCP in OS X shows an intermittent data transfer during the timeout retransmission invoked by bursty losses, which takes several seconds for retransmitting all of the lost packets. In this paper, we give detailed results of experimental analysis. Based on this analysis, we clarify the reason for the intermittent data transfer in MAC OS X by taking account of newly introduced TCP procedures, such as F-RTO and Early Retransmit., The Institute of Electronics, Information and Communication Engineers, 22 Jan. 2015, Technical report of IEICE.

We propose a routing protocol for drive-thru Internet access in delay tolerant vehicular networks. The contribution of this paper is two-folds. First, we propose a new approach which utilizes the concept of delay tolerant network (DTN) to supplement the conventional communication approach. Second, we propose an algorithm to schedule DTN transmissions in order to maximize the system throughput. The proposed protocol is able to attain higher TCP throughput than the conventional approach by providing more efficient wireless resource utilization. We use computer simulations to evaluate the proposed protocol., The Institute of Electronics, Information and Communication Engineers, 22 Jan. 2015, Technical report of IEICE.

We present performance evaluation results of a QoS supporting ad hoc network protocol which employs a hybrid approach utilizing both TDMA and 802.11 DCF. In the protocol, TDMA period provides contention free transmissions for QoS flows, and DCF period is used to provide contention-based access for best effort or low priority flows. TDMA time slots are assigned on admission basis in a distributed manner by utilizing network routing information and considering current assignment situation. In DCF period, frames are transmitted without disturbing the TDMA period. We evaluate the protocol for various numbers of best effort flows with QualNet simulator. Simulation results show that the protocol is able to provide an efficient solution for QoS control in ad hoc networks by combing TDMA and 802.11 DCF., The Institute of Electronics, Information and Communication Engineers, 22 Jan. 2015, Technical report of IEICE.

Girry Kale Timothy; Ohzahata Satoshi; Wu Celimuge; Kato Toshihiko
The Tor network is a distributed circuit-switching overlay network, and consists of voluntarily run onion routers around the world. Tor is vulnerable to network congestion and performance problems, due to circuit traffics with different rates are competing to transfer their data on a single TCP connection. A large fraction of available network capacity is consumed by the bulk users' traffic, resulting in increasing delays for the light interactive users. The unfair distribution of circuit traffic makes a bottleneck in Tor output buffer. We apply the circuit switching method and make the OR to construct a multiple TCP connections to improve the traffic flow rate and reduce the congestion in the Tor network. This approach increase the OR capacity and fairly distributing the multiple traffics that are competing to send data. The proposed method was evaluated on our setup ORs that are online in the Tor network. The experimental results show that TCP socket buffers and Tor network capacity are utilized and circuit congestion is reduced., The Institute of Electronics, Information and Communication Engineers, 16 Oct. 2014, IEICE technical report, 114, 252, 87-92, English, 0913-5685, 110009958945, AA11546431 - Characterization of TCP Congestion Control Algorithm by Estimating Congestion Window : Increase Relation and Decrease Parameter
Oda Atsushi; Wu Celimuge; Ohzahata Satoshi; Kato Toshihiko
Recently, according to the diversification of network environments, a lot of TCP congestion control mechanisms have been introduced. Since the congestion control algorithms affect the performance of the Internet, it is important to analyze which algorithms are used widely. This paper proposes a passive scheme to characterize individual congestion control algorithms by (1) estimating congestion window at round-trip time intervals, (2) correlating window sizes and their increases, and (3) identifying the discrete coefficient of congestion window. Our scheme aims at dealing with many of recent proposed congestion control algorithms including TCP Vegas, TCP Veno, Cubic TCP and TCP Illinois., The Institute of Electronics, Information and Communication Engineers, 11 Sep. 2014, Technical report of IEICE.

Wang Weikai; KATO Toshihiko; WU Celimuge; OHZAHATA Satoshi
Currently, large amount of data are transferred through the Internet. TCP plays an important role in this data transfer for the reliable data delivery. On the other hand, recent transmission technologies and media access control technologies realize high quality of data transmission in both backbone transport networks and mobile telecommunication networks. Therefore, packet losses detected in TCP level are considered as an indication of network congestion. However, packet losses can be caused by transmission interruptions such as handoffs in the mobile networks and protection switching in the transport networks. These packet losses are bursty because the transmission interruptions continue for tens of mili seconds through several seconds. This paper describes the results of experimental analysis of various TCP versions, several TCP versions in the Linux, that in Mac OS, against bursty packet losses. The result for Mac OS has some problem in retransmitting contiguously lost packets. This paper shows a detailed packet level analysis of TCP behaviors and points out that the key is the retransmission invoked by TCP SACK option., The Institute of Electronics, Information and Communication Engineers, 24 Jan. 2014, Technical report of IEICE.

Girry Kale Timothy; Ohzahata Satoshi; Wu Celimuge; Kato Toshihiko
The Tor Network is a low-latency anonymity and censorship resistance network, which relaying traffics through onion routers before being forwarded to the destination. The distribution of trust offered by Tor creates resilience in the face of compromise and censorship; however, there are performance and usability issues in the Tor network. In this paper, we analyze in more details the delay contributions from different components that cause delays in the Tor nodes. We measured the application packet that passes through all the relay nodes and closely compute the sources of latency. The experimental analysis shows that the delays occurring on relay nodes are caused by the heavy circuit queuing, TCP kernel memory exhaustion and TCP advertised window not able to accept more data. We present our experimental detail analysis and measurement results as a prerequisite for addressing the Tor's poor performance and usability., The Institute of Electronics, Information and Communication Engineers, 23 Jan. 2014, IEICE technical report.

Girry Kale Timothy; Ohzahata Satoshi; Wu Celimuge; Kato Toshihiko
Tor is an anonymous network that provides privacy and anonymity to users all over the world, by relaying traffics through the three onion routers before being forwarded to the destination. In this paper, we show that Tor suffers from the performance issues, because bandwidth is limited to how much a user is willing to allocate for Tor's usage. This scenario frequently leads to increasing delays that are not tolerated by the average end-users. We discuss these delays in more detail and perform the comprehensive study to evaluate the relative contributions for delays in the node. We use a simple model to analyze the delay components that contribute to degrade the Tor performance, due to poor TCP congestion control and high traffic queuing in the buffers. We evaluate our proposed mathematical models and present our experimental results as a prerequisite for addressing the Tor's poor delay performance., The Institute of Electronics, Information and Communication Engineers, 17 Oct. 2013, IEICE technical report, 113, 244, 111-116, English, 0913-5685, 110009783040, AA11546431 - Improving VANET unicast routing protocols by using network coding and cooperative relays

We present a scheme for VANET routing protocols. The scheme uses multiple forwarder nodes to forward data and uses network coding to reduce the number of required transmissions, resulting in a significant improvement in end-to-end packet delivery ratio with low message overhead. The scheme can be used with any VANET routing protocols by simple modification. The effectiveness of the scheme is evaluated by using both theoretical analysis and computer simulations., The Institute of Electronics, Information and Communication Engineers, 17 Oct. 2013, IEICE technical report.

NOMOTO Masataka; KATO Toshihiko; WU Celimuge; OZAHATA Satoshi
IEEE 802.11n wireless LANs provide high-speed data transfer. If the radio condition becomes bad, however, the transfer rate will be reduced significantly and there will be some problems in the data transfer. So, we have evaluated the performance of IEEE 802.11n LAN by changing the distance between the access point and a station. As a result, a severe increase of round-trip time was measured in the case of low transfer rate. A reason for this increased round-trip delay will be powerful retransmission function of 802.11n. So, we propose a method to improve TCP delay performance by reducing this retransmission capability and by generating TCP segment loss intentionally., The Institute of Electronics, Information and Communication Engineers, 12 Sep. 2013, Technical report of IEICE.

WU Celimuge; OHZAHATA Satoshi; KATO Toshihiko
Due to vehicle movement, limited wireless resources and lossy feature of wireless channels, providing a reliable multi-hop communication in VANETs is particularly challenging. We present a VANET routing protocol which learns the optimal route by employing a fuzzy constraint Q-Learning algorithm. The protocol uses fuzzy logic to evaluate a wireless link is whether good or not by considering multiple metrics of signal strength, available bandwidth and relative vehicle movement. Based on the evaluation of each wireless link, the protocol learns the best route using the route request messages and hello messages. The protocol can achieve high packet delivery ratio and low end-to-end delay. We show the effectiveness of the protocol by using computer simulations., The Institute of Electronics, Information and Communication Engineers, 17 Jul. 2013, IEICE technical report.

WU Celimuge; OHZAHATA Satoshi; KATO Toshihiko
We present BR-NB (broadcast with neighbor information), a fuzzy logic based multi-hop broadcast protocol for VANETs. BR-NB achieves a low overhead by using only a subset of neighbor nodes to relay data packets. For the relay node selection, BR-NB takes account of the inter-vehicle distance, vehicle mobility and link quality by employing fuzzy logic. The expected coverage and vehicle mobility are inferred from the two-hop neighbor information which can be acquired from the hello message exchange. Since it is independent of lower layers and does not require GPS, BR-NB provides an implementation-friendly solution for broadcasting in VANETs. We use computer simulations and real-world experiments to evaluate the performance of BR-NB., The Institute of Electronics, Information and Communication Engineers, 11 Jul. 2013, Technical report of IEICE.

Packet delivery ratio and end-to-end delay are the two most important QoS (Quality of Service) metrics. In this paper, we propose a MAC layer protocol which can provide a high packet delivery ratio and low end-to-end delay for various scenarios.

DASHBYAMBA Narangerel; WU Celimuge; OHZAHATA Satoshi; KATO Toshihiko
Optimized Link State Routing Protocol (OLSR) is a well-known proactive, routing protocol for mobile ad hoc networks. OLSR reduces the number of control messages by using MPRs to forward topology control messages as compared with typical proactive protocols. Since OLSR does not consider the node mobility and signal strength condition in the MPR selection, OLSR cannot work well in a highly mobile and lossy network. In this paper, we propose a protocol to improve OLSR by considering the node mobility and signal strength in the route selection. We use network simulator to evaluate the proposed protocol's performance., The Institute of Electronics, Information and Communication Engineers, 08 Nov. 2012, Technical report of IEICE.

DASHBYAMBA N.; WU Celimuge; OHZAHATA Satoshi; KATO Toshihiko
Optimized Link State Routing Protocol(OLSR) provides a low control overhead in high-density networks by using only MPRs to forward topology control messages. Since signal strength and mobility i \ssues are not considered in the MPR selection, OLSR fails to work properly in lossy or mobile wireless networks. In this paper, we propose a fuzzy logic based MPR selection algorithm to improve the performance of OLSR. The proposed protocol selects MPRs by considering inter-node distance, RSSI and node velocity. We use computer simulations to evaluate the proposed protocol., The Institute of Electronics, Information and Communication Engineers, 27 Sep. 2012, IEICE Technical Report, 112, 218, 83-88, English, 0913-5685, 110009666597, AN1054106X - B-6-18 A Redundant Transmission Mechanism for WSNs

WU Celimuge; OHZAHATA Satoshi; KATO Toshihiko
For many wireless sensor network (WSN) applications, high reliability and low delay are required. The acknowledgement based retransmission mechanism is the most frequently used approach for providing the reliability. However, the retransmission increases the end-to-end delay especially when the number of hops from a sensor to the sink node is large. In this paper, we propose a redundancy-based approach to provide high reliability and low end-to-end delay. Redundant transmissions are used when a link is unreliable or the end-to-end delay requirement is strict. We evaluate the proposed mechanism using a wireless sensor network which consists of IRIS motes., The Institute of Electronics, Information and Communication Engineers, 05 Jul. 2012, Technical report of IEICE.

WU Celimuge; OHZAHATA Satoshi; KATO Toshihiko
Opportunistic routing can be a solution for data forwarding in vehicular ad hoc networks (VANETs). However, existing opportunistic protocols specify the forwarding nodes at the sender side and therefore the opportunism cannot be fully utilized. Most opportunistic routing protocols cannot provide a high reliability due to the lack of efficient packet reception check mechanism. In this paper, we present OFA, an opportunistic forwarding and acknowledgement protocol for VANETs. In OFA, the forwarder node selection occurs at receiver nodes. An intermediate node is selected opportunistically to acknowledge the sender on the behalf the forwarder node when the forwarder node cannot communicate with the sender node directly. OFA can fully utilize the path diversity and also can provide hop-by-hop reliability., The Institute of Electronics, Information and Communication Engineers, 12 Apr. 2012, Technical report of IEICE.

WU Celimuge; OHZAHATA Satoshi; KATO Toshihiko
Providing a reliable and efficient multi-hop broadcast in vehicular ad hoc networks (VANETs) is crucial for Intelligent Transportation Systems. In order to provide a high reliability, a retransmission mechanism is required because a packet can be lost depending on the wireless link status and vehicle movement. The retransmission can significantly increase the message overhead if the relay nodes are not selected properly. The solution involves a joint consideration of retransmission and relay node selection. In this paper, we present a broadcast scheme which provides a high reliability with a low overhead. The scheme uses a fuzzy logic based approach to select relay nodes and uses a lightweight retransmission mechanism to retransmit a packet when a relay fails. We use computer simulations to evaluate the performance of the scheme and show the simulation results., The Institute of Electronics, Information and Communication Engineers, 03 Nov. 2011, Technical report of IEICE.
