摘要:Mobile Ad Hoc Networks (MANET) are the collection of mobile nodes without any centralized infrastructure. The underlying assumption is that the intermediate nodes cooperate in forwarding packets. Mobile nodes collects the route information through overhearing and stores these information in route caches with the use of Dynamic Source Routing (DSR) Protocol. These nodes consume power unnecessarily due to overhearing the transmissions of their neighbors. Due to this, the network performance is improved but more energy consumption occurs unnecessarily. The main goal of the work is to reduce the effect of overhearing using the Demand Based Energy Efficient (DBEE) algorithm. The mobility of the nodes results in stale routes, due to the lack of route cache updation. For that, a cross layer framework is implemented along with the DBEE to improve route cache performance in DSR. By using the cache timeout policy we can easily prevent stale routes from being used. The cache timeout of individual links are found by Receiving Signal Strength Indicator (RSSI) information. By simulation results the proposed algorithm achieves better performance than the existing methods.
