Research on route protocols of WiFi-based Ad-hoc network

Based on the background of WiFi-based Ad-hoc network, four route protocols are simulated using OPNET plat form. Experimental result shows that AODV protocol has a better performance than other algorithms under the circumstance of high throughout and heavy burden. To meet the communication requirement of vehicle-borne Ad-hoc network under battlefield circumstance, a ne w cluster route protocol (CRP) is proposed based on AODV protocol. Its cluster architecture design reduces the influence of topology change on route search process and the flooding cost during route discovery process. It is proved that the performance of CRP is better than AODV protocol and ZRP protocol, and the end-to-end delay is reduced dramatically.
