Abstract: Route discovery and route maintenance concerns a main issue in MANET. To address this problem we propose an efficient hybrid routing technique using Priority Acknowledgement Table. Our proposed work uses both Ondemand and Table driven routing protocols for continuous route discovery between source and destination in multipath and multicast environment. Here we use a Priority Acknowledgement Table technique to find the shortest alternative path. In initial stage a single route is discovered using On-Demand routing protocol. From that route each node involves in continuous discovery of another shortest path to reach destination. At that time if a node finds more than two alternate paths, then it is declared as DPN and a temporary PAT is constructed from which again a new route is discovered to reach the destination. In our proposed work if route failure occurs, route rediscovery starts from DPN instead of from original source node by which efficiency is increased.
