Description
Summary:Ad hoc networks play important roles in next generation mobile systems. They have not any wired infrastructure support. In ad hoc networks, nodes change their position frequently and each node can act as a router. Due to high mobility and frequently links breakage, selecting the reliable path is a critical challenge. Multimedia applications need robust path as a key issue for achieving higher performance. In this paper, we propose a new metric to add to the routing table to achieve this. By exploiting the routing table stability parameter (RTSP) in each node, we can predict fragile routes and thus provide a mechanism to select robust path to increase efficiency. Each node computes RTSP in a distribution mechanism and adds this metric to route request and reply packets. We use Global Mobile Simulation (GloMoSim) environment to simulate our method. Routing in mobile ad hoc networks (MANET) with considering RTSP factor improves packet delivery ratio. Simulation results also demonstrate that adding RTSP factor to routing table improves throughput and but slightly increases end-to-end delay with increasing mobility.
