Solving Reliable Coverage In Fault Tolerant Energy Efficient Wireless Sensor Network

With the strong push from applications, fault tolerant and energy efficient property of wireless sensor network has gradually become a hot point. Based on the heuristic method used to generate minimum covers, a novel scheme namely reliable coverage scheme is proposed to solve the reliable coverage problem within the cluster in a hierarchical structured network. Simulations show that this scheme is able to efficiently utilize energy to prolong network lifetime while at the same time keeping missed monitoring at a low level
