Fault Detection and Correction in Using Shortest Path in Wireless Sensor Networks

Abstract

Wireless sensor network is a self-organized network that consists of a large number of low-cost and low-powered sensor devices, called sensor nodes. Recent advances in wireless sensor networks have resulted in a unique capability to remotely sense the environment. These systems are often deployed in remote or hard-to reach areas. Hence, it is critical that such networks operate unattended for long durations. Unlike the cellular networks and ad hoc networks where energy has no limits in base stations or batteries can be replaced as needed, nodes in sensor networks have very limited energy and their batteries cannot usually be recharged or replaced due to hostile environments.
