Abstract

This article addresses the behavioral characteristics of faults, errors and failures in wireless sensor network. Viable usage of compact limited resource constrained microsensors for advance deployment tends to face more challenges during the execution of various event handling and this action reflects to obtain deviated result from reaching the targeted goals. Achieving the targeted goals beyond the limitations necessitate special investigation of possible arising faults. Although many fault management approaches are addressed, none has focused on faulty issues at the wireless sensor network protocol stack level and also at sensor nodes’ component side. Addressing and exploring various impacts of faults, errors and failures at different layers of wireless sensor network protocol stake and at the level of inter-functional units of sensor node components are concerned to be the main theme of this paper. Moreover, the overall investigation along with three phases (prevention, diagnosis, and recovery) of fault management furnishes generic life-cycle of fault tolerance management with potential basic relevant parameters.
