A new source routing mechanism in mobile ad-hoc network

The inherent uncertainty in wireless mobile ad hoc networks (MANET), due to nodal mobility, unstable links, and limited resources, frequently renders routing paths unusable. Due to the unpredictable movement of mobile nodes, the network topology of a mobile ad hoc network changes frequently. It will directly cause the routes to be broken and greatly degrade the network performance. However, selecting an optimal path set is a NP hard problem. In this paper, we propose source select rout (SSR) a novel Reliable Routing Algorithm in mobile ad hoc networks. In SSR source using fuzzy logic to select optimized path between the source and destination. We take into account three important factors as the selection parameters; which are the maximum distance between intermediate nodes, maximum relative speed between neighbor nodes, and total number of data transmission links in the intermediate nodes. Simulation results demonstrate the superiority of the proposed technique over conventional MANET routing schemes.
