Switching Method of Single Radio Multi-Channels for Vehicular Ad hoc Network

School of Communication and Information Engineering,University of Electronic Science and Technology of China Chengdu 611731

摘要: 提出一种单接口多信道的切换方法,它能够动态判定网络中的节点密度和服务信息流量。节点密度较大,且服务信息流量较大的节点划分为α模式;节点密度较大,但服务信息流量较小时划分为β模式;其余情况的节点划分为γ模式。根据不同模式的特点,采用不同的报文发送模式,并且给出3种模式之间的动态判定和切换方法。在OMNET++平台上,以SUMO为交通模拟器,选用Veins款开源的车辆间通信模拟仿真框架,对该切换方法进行仿真和性能评估。

Abstract: This paper proposes a multi-channel switching method to consider the node density and service traffic. The nodes in the network are divided into three modes according to the node density and service information flow in nodes. The message is delivered in different patterns for different modes. The judging of the three modes and switching between them are studied. The switching method is simulated on OMNET++ platform and its performance is evaluated.
