摘要: 针对目前城市环境中车载自组织网络车辆节点分布不均衡引起的消息传递冲突率高、传递效率低、路由可靠性差等问题,在IF(Irresponsible Forwarding)算法的基础上提出一种带有冲突估计的节点转发策略(NFCE算法)。收到消息的车辆节点首先确定自身的转发冲突概率,在不超过一定门限值的条件下,再根据节点的密度、通信半径大小以及到源节点的距离来确定自己的转发概率,最终概率大的节点优先转发消息。仿真结果表明,相比于其他算法,NFCE算法降低了节点传递冲突率,其路由有更高的效率和可靠性,特别在车辆密度较大时NFCE算法有明显的优势,更适合应用在城市环境中。

Abstract: Aiming at the problem of high collision rate in message transmission,low transmitting efficiency and unreliable routing caused by the uneven distribution of vehicles in urban vehicular ad hoc networks,a node forwarding strategy with collision estimation (NFCE) was proposed based on irresponsible forwarding (IF) algorithm.Firstly,the vehicular node receiving message from others determines the probability of collision in forwarding message.If the probability is below a certain threshold,then the node determines its own forwarding probability on the basis of the node density around it,its communication radius and its distance from the source node.Finally the node with higher forwarding pro-bability has more priority to forward the message.Simulation results show that,compared with other typical algorithms,the NFCE algorithm reduces the rate of transmission collisions,its routing has higher efficiency and reliability than others especially in large vehicle density of urban environments,so NFCE is more suitable for application in urban environment.
