Weighted distributed fault detection for wireless sensor networks Based on the distance
Zhen Feng, Jing Qi Fu, Yang Wang · 2014
In wireless sensor networks, this paper puts forward a distributed fault detection algorithm to solve the node failure problems. It takes into account the spatial correlation of network node, based on the way of weighted distance, compares its own reading with the weighted value to judge the fault node. Finally, the feasibility and effectiveness of the algorithm is demonstrated via computer simulation. The simulation results show that the correct rate of fault detection is improved, and the false alarm rate of fault detection is reduced.
