As the wireless sensor network has made its steps in mobility based applications like health monitoring, wildlife monitoring, search and rescue, it is desirable to have a reliable routing protocol to deal with the routing issues of mobile sensor nodes and battery is also the main constraint for sensor nodes so routing protocol should be energy efficient. Existing approaches for routing in Cluster Based Mobile Wireless S ensor Network (MWS N) considered nodes equipped with GPS for getting its location and delay in joining the mobile node that get out of the cluster in joining new cluster is high. Also the routing between cluster heads is not discussed in existing approaches. S o in this study, the fault tolerant routing protocol has been proposed that achieve fault tolerance of cluster heads while routing and mobility management of mobile sensor nodes to reduce packet loss during data transmission in MWS N.
