| Abstract: | In order to maximize the network lifetime for target coverage,we propose a distributed optimum coverage algorithm for point target in wireless sensor networks according to the distributed self-organizing characteristics of wireless sensor networks. We analyzed the network model for target coverage,introduced the definition of key target,designed an energy utility function based on the target's coverage energy,set the waiting time according to the priority of key target and maximum energy utility,and establi... |
