  • Multihop Broadcast Protocol in Intermittently Connected Vehicular Networks
    IEEE Transactions on Aerospace and Electronic Systems, 2018
    Co-Authors: Chakkaphong Suthaputchakun

    Abstract:

    There are great challenges in vehicular networks, i.e., continuous connectivity cannot be guaranteed due to interruptions. This paper proposes a novel multihop Broadcasting Protocol with low signaling overhead in vehicular networks with frequent interruptions named as trinary partitioned black-burst-based Broadcast Protocol. The Protocol operates without any infrastructure. It has low overhead supporting different quality of service levels. Both analysis and comprehensive simulations show that the proposed Protocol outperforms the bench mark schemes.

  • Trinary Partitioned Black-Burst-Based Broadcast Protocol for Time-Critical Emergency Message Dissemination in VANETs
    IEEE Transactions on Vehicular Technology, 2014
    Co-Authors: Chakkaphong Suthaputchakun, Mehrdad Dianati, Zhili Sun

    Abstract:

    In this paper, we propose a multihop Broadcast Protocol for dissemination of time-critical emergency messages (EMs) in vehicular ad hoc networks (VANETs), where the IEEE 802.11p technology is used for communication among the nodes. The proposed trinary partitioned black-burst-based Broadcast Protocol (3P3B) consists of two primary mechanisms. First, a mini distributed interframe space (DIFS) in a medium access control (MAC) sublayer is introduced to give the time-critical EMs a higher access priority to the communication channel compared with other messages. Second, a trinary partitioning is designed to iteratively partition the communication range into small sectors. The trinary partitioning mechanism allows the farthest possible vehicle in the farthest sector from the sender node to perform forwarding to increase the dissemination speed by reducing the number of forwarding hops. In addition, 3P3B reduces the contention period jitter, which is independent of the density of vehicles, resulting in a more stable contention period. Analytical models are proposed for performance evaluation in conjunction with simulation-based performance analysis. The results demonstrate that 3P3B outperforms benchmarks of the existing Broadcast Protocols in VANETs in terms of the average message dissemination speed, message progress, communication delay, and packet delivery ratio.

  • Trinary Partition Black-Burst based Broadcast Protocol for Emergency Message dissemination in VANET
    2013 IEEE Wireless Communications and Networking Conference (WCNC), 2013
    Co-Authors: Chakkaphong Suthaputchakun, Mehrdad Dianati

    Abstract:

    In this paper, we analyze the current binary partition multi-hop Broadcast Protocol and propose an enhanced solution, namely, Trinary Partition Black-Burst based Broadcast Protocol (3P3B) for Emergency Message (EM) dissemination. 3P3B provides low and constant latency regardless density and size of networks compared to existing solutions. It also enhances message dissemination speed and message progress distance. The main technique in the 3P3B is that 3P3B uses mini-slot DIFS to give a preemptive priority to very urgent EMs and deploys a trinary partition mechanism to select the furthest forwarder of the next communication hop. We prove that 3P3B recues the delay, increases dissemination speed, message progress distance, and outperforms the well-known existing Broadcast Protocols for EM dissemination in VANET.

  • An Intelligent Broadcast Protocol for VANETs Based on Transfer Learning
    2015 IEEE 81st Vehicular Technology Conference (VTC Spring), 2015
    Co-Authors: Celimuge Wu, Yusheng Ji, Xianfu Chen, Satoshi Ohzahata, Toshihiko Kato

    Abstract:

    Designing an efficient multi-hop Broadcast Protocol is very important for the realization of collision avoidance systems and other many interesting applications in vehicular ad hoc networks (VANETs). Existing Protocols are optimized for a specific scenario, and are not capable of working in various scenarios. Therefore, designing an intelligent Protocol which can tune itself in relation to the change of network environment is particularly important. In this paper, we propose a Broadcast Protocol which is able to make forwarding decision based on a self-learning mechanism. The Protocol employs a fuzzy logic-based relay node selection approach to take into account multiple metrics for the forwarding algorithm. The parameters used for the fuzzy logic are tuned online using a reinforcement learning approach. Transfer learning is used to transfer knowledge to new arriving vehicles (agents) in order to shorten the convergence time. The combination of reinforcement learning, transfer learning and fuzzy logic can provide an intelligent solution for Broadcasting in VANETs. We conduct computer simulations to evaluate the proposed Protocol.

  • Joint MAC network layer Broadcast Protocol for vehicular ad hoc networks
    2013 IEEE International Conference on Communications Workshops (ICC), 2013
    Co-Authors: Celimuge Wu, Satoshi Ohzahata, Toshihiko Kato

    Abstract:

    Packet dissemination ratio and end-to-end delay are the two most important metrics for multi-hop Broadcast Protocols in vehicular ad hoc networks (VANETs). In this paper, we propose a joint MAC network layer Broadcast Protocol. The proposed Protocol uses selected relay nodes to forward packets. A reliable communication is conducted between the sender node and each relay node by using MAC layer acknowledgments. The Protocol can provide a low delay and high packet dissemination ratio by reducing the packet loss detection delay and providing retransmissions at the MAC layer. We show the effectiveness of the proposed Protocol by using both theoretical analysis and computer simulations.
