In order to preserve the coverage and ensure the efficiency of Wireless Sensor Networks (WSNs), a distributed coverage-hole repair algorithm towards nodes failure is proposed in this paper. Every node has a energy threshold, if node’s energy is lower than its threshold, it sends a failure message to the nearest node and appoints it as the head node, the head node consideres all the neighbors of the failure node are preparatory boundary nodes at first, then judges every preparatory boundary nodes whether be a non-boundary node through the intersection angle with the failure node. In the last, the head node activates the redundant node within the sensing range of failure node which has the most boundary nodes as neighbor nodes. Analyzes and simulation on Matlab platform indicate that this algorithm has a low time complexity and the repair efficiency has a grate relation with node density and node sensing radius.
