Abstract
Dynamic Source Routing (DSR) is an efficient reactive routing protocol for mobile ad hoc networks, in which only needed routes are found and maintained. Route caching is employed to avoid the need for discovering a route before each data packet is sent. DSR employs caching of routes to increase the protocol efficiency. However, the absence of any opportune mechanism to remove cache entry causes cache to contain stale information, also the aggressive use of cache cause dissemination of stale route information, which leads to delay and increases loss rate in high mobility scenario. In this paper, we propose a dynamic mechanism which computes Expected Link Expiration Time (ELET) using cross layer parameter which timely removes the stale cache entry from route cache, also an updated route reply method is used to prevent dissemination of stale routes. Simulation results in NS2 show that enhanced DSR (EDSR) cache scheme can swiftly adapt to scenario changes and can perform better than the existing caching scheme.
