Abstract

A wireless communication system to operate efficiently in the industrial/factory floor environment has to guarantee low and probable delay of data transfer (typically, less than 10 ms) for actual time applications. Faults occurring in sensor nodes are familiar due to the sensor device itself and the unkind environment where the sensor nodes are deployed. WSNs are mainly affected by the crash of sensor nodes. MANET nodes may experience two types of faults that would direct to the degradation of performance. First type is function fault, which normally stops the working of individual nodes, packet failure, routing failure or network separation. The other type of error is data fault, in which a node behaves normally in all aspects except giving its sensing results, leading to either major inclined or random errors.
