Research and Optimization of GPSR Routing Protocol for Vehicular Ad-Hoc Network
文献摘要：
Security is one of the most critical issues to Vehicular Ad-hoc Networks(VANETs)since the in-formation transmitted is asynchronous and distributed.Vulnerability and instability are two of the challenges remain to be addressed by the research community and the industry.In this paper,we first proposed a trust reliability based model and extended the GPSR pro-tocol to TM-GPSR protocol.Then,we improved the LET-GPSR protocol based on the link connection time prediction.On this basis,combined the decision index of the TM-GPSR and LET-GPSR protocols,we pro-posed the RC-GPSR routing protocol.We built the standard testing platform on the NS2 and SUMO,the average end-to-end delay and packet delivery rate of GPSR protocol and the three updates protocols under different node density,node speed,and malicious node ratio are simulated and evaluated.The results showed that under the same conditions,compared with GPSR protocol,RC-GPSR protocol has a lower average end-to-end delay and a higher packet delivery rate,which effectively improves the link stability and security.
