Abstract:
Wireless sensor network is usually deployed in harsh environment which affects nodes’ operation and might cause faults in the applications. Fault diagnosis in wireless sensor network is essential for planning to manage and prevent those faults in appropriate time period and reduce the damage in the network to help the network operate effectively Previous fault diagnosis schemes in wireless sensor network detect and report faults in terms of faulty nodes or links which cost high overhead in network. In contrast, individual node or link malfunction might not affect network operation or might cause slightly damage.

Therefore, region-based fault diagnosis scheme was proposed to diagnose and report wireless sensor network’s status by using region representation to reduce overhead and increase effectiveness when integrate fault diagnosis scheme with other applications.
