Route stability based on demand multipath routing protocol for Mobile Ad Hoc Networks

A fundamental issue arising in Mobile Ad Hoc NETworks (MANETs) is to select a reliable routing path between nodes to improve routing efficiency by selecting the most stable path so as to reduce the packet drop rate and overhead due to route rediscovery. In this paper, we propose to design a route stability based on demand multipath routing protocol for MANETs named, Stable Backbone based Multipath Routing Protocol (SBMRP) to improve link quality and to select a stable paths between the nodes. Proposed scheme includes selection of candidate nodes and construction of routing backbone to select the stable paths between the source to the destination node. The proposed algorithm has been verified by simulations using Network Simulator 2 (NS-2). The results have been show that the SBMRP outperforms the existing routing protocols by significantly reducing the route discovery and also increases packet delivery ratio and lifetime of nodes by constructing backbone paths between source and destinations.
