AOMDV routing algorithm for Wireless Mesh Networks with local repair (AOMDV-LR)

One of the main challenges of Wireless Mesh Network is the design of robust routing algorithms that adapt to the frequent and randomly changing network topology and provide various alternate routes from source to destination. Several Multipath routing protocols have been proposed to efficiently transmit data among the participating nodes that enables data transmission over alternate paths when active path is failed. The Ad hoc On Demand Multipath Distance Vector (AOMDV) Routing Protocol is one of the most commonly used reactive protocols for multipath routing in Wireless mesh networks. AOMDV performs well, but it does not has local repair capabilities such as it uses backup route for further transmission during the failure but when no back-up route is available it restart route discovery from source to destination that degrades throughput and increases end to end delay. To overcome this problem, we present an AOMDV protocol with local repair capabilities (AOMDV-LR). In this approaches intermediate nodes in the existing paths try to find new path to the destination in the event of link failure and when no alternate route available.
