The covering problem and node deployment is a fundamental problem in the research into wireless sensor networks. The number of nodes and the coverage of a network can directly affect performance and operating costs. For this reason, we propose Event-driven-mechanism Coverage Control Protocol (ECCP). The algorithm uses the correlation between the nodes and dynamic grouping to adjust the coverage area. Within the coverage area, we use the greedy algorithm to optimize the coverage area. So the target node is uniformly covered by other sensor nodes and the network resource is optimized. To ensure the energy balance in the wireless sensor network and extend its lifetime, we only wake partial nodes to work in a cycle, so that they can work in turn. Experiments show that the algorithm can effectively reduce energy consumption, with better adaptability and effectiveness.
