An approach for efficient multipath routing in wireless sensor networks

Wireless sensor applications such as multimedia surveillance, storage of potential relevant from network cameras, city traffic monitoring are designed to intimate the changes in the real world. We need fast, reliable protocol to meet the constraints such as loop free path, communication delay, route failure and load balancing. Multiple path networking is one of the methods to ensure the QoS. Numerous protocols have been proposed such as AOMDV, AODV_multipath, and MCP_DE, to identify the multiple paths but they failed to locate the failure at route discovery. We propose an algorithm to identify the disjoint paths, spot the bottle neck nodes, identify route failures and specify when to transmit the RREQ in mobile nodes in the network. Our protocol will give better throughput, delay performance and cost beneficial.
