An Improved Routing Protocol (AODV nthBR) for Efficient Routing in MANETs
Mobile Ad Hoc Networks (MANETs) are a self-configuring network of mobile nodes characterized by multi hops and forming a dynamic wireless topology. Efficient routing protocols are the backbone of MANETs and enable the network to support various Quality of Service (QoS) parameters. Most of the routing protocols like Ad Hoc On Demand Distance Vector (AODV) send packets via a single route. However, failure of this single route results in decline of performance of MANETs. Providing a single backup route does not solve the problem completely as the failure of the backup route again leads to lower QoS parameters. This paper proposes AODV routing protocol with nth backup route (AODV nthBR) that provides source node with more than one back up routes in case of a link failure. The proposed scheme results in better throughput, improved packet delivery fraction and lesser end to end delay.
