A low overhead stability-aware multipath routing protocol for MANETs

In a mobile ad hoc network wireless links are broken frequently because of mobility of nodes. It leads to many routing processes and consequently wastage of the network resources such as energy and bandwidth. Using a routing protocol that reduces the link breakages will result in lower overhead and less packet losses. In this paper we propose a reliable multipath routing protocol that finds stable paths from a source node to a destination node. Our protocol verifies the paths that are being discovered link by link. Each link should satisfy a fairly chosen threshold. If it doesn´t, it will not be used in the paths. Therefore, the paths which are stable and reliable will be constructed. Simulation results show that our protocol reduces the routing overhead and the energy consumption at the same time with improving packet delivery ratio and throughput, especially in high mobility scenarios.
