Optimization on Cache Management Strategy of DSR Protocol

DSR protocol could not take full advantage of the potential routing information, and the expired routing in routing cache influences the routing accuracy, thus there exists the problem overhead additional overhead from data packet. This paper presents an optimal scheme in the cache management strategy, that is, the combination of link cache with "timeout" mechanism, thus reducing the cost of data-packet head, taking full advantage of the potential routing information, guaranteeing the routing accuracy in routing cache. The simulation results show that the optimized protocol could significantly reduce the network overhead and time delay.
