DFDM: Decentralized Fault Detection Mechanism to Improving Fault Management in Wireless Sensor Networks
Wireless Sensor networks (WSN) are inherently faultprone due to the shared wireless communication medium and harsh environments in which they are deployed. Energy is one of the most constraining factors and node failures due to crash and energy exhaustion are commonplace. In order to avoid degradation of service due to faults, it is necessary for the WSN to be able to detect faults early and initiate recovery actions. In this paper we propose a decentralized cluster based method for fault detection and recovery which is energy efficient namely DFDM. Simulation Results show that the performance of proposed algorithm is more efficient than previous ones.
