Stable Backbone Based Multipath Routing Protocol for Mobile Ad-Hoc Networks

Mobile Ad-Hoc Networks (MANETs) consists of wireless mobile nodes communicating without the need of services provided by a centralized administration or established infrastructure. They can be setup anywhere and anytime because they require neither infrastructure nor centralized administration. Because of mobile nodes in MANET, high node mobility causes complexities in route discovery, route stability etc. in which stability is the main reason for data failure. In most of the existing stability based routing protocol link quality and residual energy of each node is estimated during the routing process, result increased delay and overhead. In order to overcome these issues, in this paper, we construct a Stable Backbone Based Multi-Path Routing Protocol for Mobile Ad-Hoc Network (SBMRP). Initially, the nodes with high residual bandwidth, residual power, link quality and low mobility nodes are designated as candidate nodes. Then multiple paths are established between source and destination through these candidate nodes, thus forming a routing backbone. If any candidate node in the path tend to fail due to lack of bandwidth, residual energy or link quality, alternate path through another candidate node is established. By simulation results, we show that proposed technique minimizes the overhead, packet drop, energy and increases the packet delivery rate.
