Fault-tolerant multipath routing scheme for energy efficient wireless sensor networks

Themain challengein wireless sensor network is to improve the fault tolerance of each node and also provide an energy efficient fast data routing service. In this paper we propose an energyefficient node fault diagnosis and recovery for wireless sensor networks referred as fault tolerant multipath routing scheme for energy efficientwireless sensor network (FTMRS).The FTMRSis based on multipath data routing scheme. One shortest path is use for main data routing in FTMRS technique and other two backup paths are used as alternative path for faulty network and to handle the overloaded traffic on main channel.Shortest path data routing ensures energy efficient data routing. The performance analysis of FTMRSshows better results compared to other popular fault tolerant techniques in wireless sensor networks.
