MFTR: Multipath Fault Tolerant Routing in Wireless Sensor Networks

In the modern age huge amount of wireless sensor networks is used for security surveillance and environments monitoring. The main challenge is to improve fault tolerance percentage of wireless sensor networks and also provide an energy efficient fast data routing service. In wireless sensor networks energy conservation is most significant because every sensor node has a constant power supply. In this paper we propose an energy efficient multipath fault tolerant routing protocol in wireless sensor networks referred as MFTR. The MFTR use multiple data routing path for fault tolerance and traffic control. One shortest path is use for main data routing in MFTR technique and other two backup paths are used as alternative path for faulty network and to handle the overloaded traffic on main channel. The performances analysis of MFTR depicts better result compare to other popular fault tolerant techniques in wireless sensor networks.
