英文摘要： Because of restriction of capacity and poor working conditions, Wireless Sensor Network (WSN)'s nods are easy to failure to reduce the efficiency of work and quality of services. This project is aimed at the questions of network connectivity and data credibility, which led by WSN nodes fault, and will study WSN fault management technology and algorithm from the angle of the service. In order to improve WSN nodes' fault tolerance ability, the project will study coverage control and clustering algorithm with reasonable redundancy. These will improve the WSN nodes' fault tolerance ability in physical connection level and logical connection level. This project will study selection algorithm of detection probe and will present the algorithm of detection routing. By constructing a data analysis model and node credit system, the project will find WSN fault node which does not provide the credible data. The project also will research the WSN fault recovery technology, The project will recovery the link node failure based on connected set, and wil recovery the link failure peripheral node faultd through the task migration and neighbor node cooperation.
