Cache-Aware Query-Broadcast to Improve QoS of Routing Protocols in MANETs

Recent research in Mobile Ad-hoc Networks mostly deals to minimize the congestion in the network. In this regard, a variety of query-broadcast techniques have been proposed, and employed to reduce routing overhead such as the congestion, route-latency and energy-consumption. Such techniques mainly focus on reducing unnecessary propagation of route-query by repealing the query-broadcast. In our research findings, we found these repealing techniques have extra routing-overhead of chasing the route-query thus increasing energy-consumption and slowing down the route-discovery. In particular, this motivates us to propose a cache-aware broadcasting technique. In order to evaluate the proposed technique, the critical and analytical assessment is done in terms of query-diffusion, route-latency, packet-delivery ratio and energy-consumption ratio.
