Taking WiFi-based Ad-hoc network as an application background, the performance of 4 typical Ad-hoc network route protocols are simulated and compared by using simulation platform OPNET. The experimental re-sult shows that reactive route protocol has a better performance than that of pre-active routing algorithm, and the AODV protocol has more excellent performance because of its characteristics of backup route. A novel cluster Ad hoc network route algorithm CRP is presented by combining advantages of AODV algorithm to meet the large scale netting requirement of vehicular Ad-hoc network under battlefield circumstance and time delay transmission re-quirement for the fire control data. Its cluster architecture design reduces effect of network topology changes on route searching process and flooding cost during route discovery process, and speed up the searching process of route. The simulated results indicate that the integrated performance of this algorithm is better than that of the AODV algorithm and typical clustering route protocol ZRP algorithm, and the end-to-end transmission time delay is reduced distinctively.
