Improvement of Link Break of AODV in Ad-hoc Networks

Because of the flexibility and convenience it can provide us, the mobile ad-hoc network becomes a very hot research topic presently. There are many related articles presented on various journals in this area, especially concentrated on the ad-hoc routing protocols. But, the solutions provided still have more or less defects. Firstly this article introduces the special characters of ad-hoc network and the existing routing protocols. Then analysis and simulation of the link break of ad-hoc on-demand distance vector in ad hoc networks are presented and a new mechanism to improve the performance of link repair is provided. The simulation results indicate that the improved method results in less delay and routing overhead while reconstructing route compared to the traditional method to some extent.
