An Improved Scheme for Reducing the Latency of AODV in Ad Hoc Networks

Because of the flexibility and convenience, the mobile ad hoc networks have become a very hot research topic. This paper begins with an introduction about the characteristics of mobile ad hoc networks and the existing routing protocols. Then an analysis of the latency of AODV in mobile ad hoc networks is represented and a new mechanism is provided. The improved protocol forecasts the latency in the stage of route discovery and uses an improved local repairing scheme in the stage of route repairing. At last, simulations are done using NS2 for the improved protocol. According to the result, the improved protocol can reduce the delay of the routing in mobile ad hoc networks.
