Zigbee路由协议在VANET监控系统中的应用分析

本文以VANET的应用需求为出发点，提出一种基于双层拓扑结构的网络模型，并使用Network Simulator 2．0版软件完成了模型仿真，分析了簇树、AODVjr以及ZBR三种路由协议在相同车联网环境下的性能表现。最终表明，ZBR路由协议能够在确保较短时延以及较高分组递交率的条件下，很好地实现网络开销的降低。

Zigbee routing protocol in the analysis of application of VANET monitoring system

Based on the application of VANET demand as the starting point, this paper puts forward a network model based on two?layer topology, and uses the Network Simulator version 2. 0 software to complete the model simulation. After that, the paper analyses the performance comparison among three types of routing protocols such as the cluster tree、the AODVjr and ZBR under the same networked environment. Eventually the paper shows that ZBR routing protocols could ensure shorter time delay and higher packet submit rate under the condition of good implementation, and efficiently reduce network overhead.
