A Fast Multipath Routing Protocol for wireless sensor networks

Multipath routing has been widely used in wireless sensor networks to improve mainly the network performance by providing the load balancing capabilities. However, high correlated paths can throttle data transfer and can cancel the benefits of using multiple routes for data forwarding towards the sink. In this context, we propose a Fast Multipath Routing Protocol (FMRP), a query based multipath routing protocol which provides a simple mechanism during the discovery phase to construct node-disjoint paths while minimizing the impact of collision and interference. Thus, selecting less correlated paths allows a fluent data transfer and an efficient resources use. The good performance of our protocol in terms of more energy saving and better network throughput is witnessed by extensive simulations under various traffic loads and adopting different scenarios.
