The Method for Developing Fault Tolerance in Mobile Sensor Network

Excerpt

Wireless Sensor Networks become a new information collection and monitoring solution for a variety of applications. Faults occurring to sensor nodes are common due to the sensor limitations and the harsh environment sensor networks. The fault sensor's lowest effect in network efficiency or in other word sensor network has fault tolerance. In this paper is studied the fault tolerance problem from the coverage point of view for sensor networks. In the proposed method missing regions with faulty sensors recoup by its neighbors and using minimum redundant sensors. After, a sensor node become fault, coverage loss caused covered by its neighbors movement to failure node. In proposed method major problem is election neighbor node for movement. The priority of neighbor nodes for movement and coverage missing regions determines by overlapping sensing range and distance from faulty node. When determined priority neighbors, move a neighbor with high priority to faulty sensor node. The proposed method in this paper compared with previous approaches which used from redundant sensors only.
