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. Therefore, extending network lifetime through the efficient use of energy has been a key issue in the development of wireless sensor networks. In distributed fault detection (DFD) scheme for wireless sensor networks the status of each sensor node to be either good or faulty is based on the neighboring nodes, but in the DFD algorithm[1],when the sensor fault probability increases the fault detection accuracy decreases and the false alarm rate increases rapidly. In this paper an improved DFD scheme is proposed to detect intermittently faulty sensor nodes and to stringent power budget during fault diagnosis process on sensor nodes in wireless sensor network. Simulation results demonstrates that the improved DFD scheme reduce energy consumption in comparison with previous algorithm. The proposed mechanism is implemented with MATLAB.
