Abstract : n this paper, we propose an optimal fault-tolerant algorithm for distributed event detection in wireless sensor networks. Two important problems are addressed: 1. How to handle both the noise-related measurement error and sensor fault simultaneously in fault-tolerant detection? 2. How to choose a proper neighborhood size n for a sensor node in fault correction such that the maximum energy could be conserved? Both theoretical analysis and experimental results confirm the effectiveness and efficiency of the proposed algorithm.
