城市场景车载Ad Hoc网络竞争转发关键参数分析

Analysis of Key Parameter of Contention-Based Forwarding Strategy for Vehicular Ad Hoc Networks in City Scenarios

论文对城市场景下的基于竞争转发的车载Ad hoc网络路由算法进行了分析,该分析对于确定竞争转发策略中节点定时器的值具有重要的意义,是竞争转发路由策略的有益和重要的补充.论文给出了保证抑制策略以一定概率执行成功的条件下,节点定时器参数的下限值.仿真和分析结果的对比验证了本文分析的有效性.

This paper proposed an analysis of the contentionbased forwarding（CBF） routing protocol for VANETs in city environments,which is very important to determine the value of the timer used in CBF.And this paper is one beneficial and important component of the routing protocol in previous paper.The lower bound of the timer was given on the condition that the suppression scheme accomplished successfully with given probability.The analysis is validated by comparing simulation and analysis results.
