摘要

摘要：分析了基于地理位置的路由协议RBVT-R。针对RBVT-R协议在路由建立过程及分组转发过程中的缺陷，提出了一种RBVT-R协议的改进算法。该算法在路由建立过程中，根据自主获取的道路车辆密度改进了RBVT-R 协议的洪泛机制；在分组转发过程中采用基于方向和位置预测的转发方法，解决了分组在同一路段重复传输的问题。仿真结果表明，提出的改进策略有效地提升了分组的交付率与端到端平均时延。

Abstract

The location-based routing protocol RBVT-R was analyzed. Aiming at the defects of RBVT-R routing protocol during the process of routing establishment and packet forwarding

an improved algorithm of RBVT-R was proposed. This method has improved the flooding mechanism by attaining road traffic density independently during the process of routing establishment. A packet forwarding scheme based on direction and location forecast was proposed during the process of packet forwarding

and had solved the problem of repeated transmission of packets in the same section. The simulation results show that the proposed improvement strategy can effectively enhance the average packet delivery ratio and end-to-end delay.
