Routing in wireless sensor networks is a self-centered task. This has led to a number of routing protocols which efficiently utilize the limited resources available at the sensor nodes. Consumption of the minimum energy path is the distinctiveness of such routing protocols. By using the minimum energy path deprives the nodes energy quickly and the time taken to determine an alternate path increases. Instead of routing all the traffic along a single path, multipath routing schemes distribute traffic among multiple paths. Two criteria that arise in multipath routing are how many paths are needed and how to select these paths. Obviously, the number and the quality of the paths selected dictate the performance of a multipath routing scheme.
