摘要：

Event monitoring is an important issue in wireless sensor networks, however, the limits of sensor networks and the uncertainty existed in sensed data propose challenges for it. This paper analyzes the uncertainty existed in sensor networks and presents fault-tolerant event monitoring mechanism. We first introduce the fault-tolerant event detection and monitoring nodes choosing algorithms, and then estimate the event appearing area under the condition of static sensor nodes and moving sensor nodes. Finally, we evaluate our algorithms via a serial of simulations. The experimental results show that the proposed algorithms can obtain optimal performance in event monitoring.
