A Grid-Based Energy Aware Node-Disjoint Multipath Routing Algorithm for MANETs

Now most of the on-demand routing protocols for current mobile ad hoc networks (MANETs) build and rely on single route for each data session. However, the single path is easily broken and needs to perform a route discovery process again due to the dynamic topology of ad hoc networks. In ad hoc networks, multipath routing is better suited than single path in stability and load balance. Because mobile nodes have limited battery power, it is therefore very important to use energy in a MANETs efficiently. In this paper, we propose a new routing algorithm called grid-based energy aware node-disjoint multipath routing algorithm (GEANDMRA). In GEANDMRA, grid partitioning is the same as in the GRID routing protocol. The main difference between these two protocols is that GEANDMRA considers energy- aware and node-disjoint multipath but the GRID does not. Simulation results indicate that GEANDMRA outperforms AODV and DSR.
