Abstract

Wireless sensor network is always deployed randomly in specific area for intrusion detection and environmental monitoring. Due to the hostile environment, the sensor nodes could not be replaced easily. The efficient energy consumption scheme is known to be more and more important. Meanwhile, saving the energy could not impact the coverage quality. Connecting proper sensors adaptively as a barrier for monitoring is a good solution for both maximizing network lifetime and providing predetermined coverage ratio. The simulation results demonstrate that the algorithms can effectively reduce the energy consumption of the wireless sensor network and also keep the coverage quality on a high level.
