An area coverage control protocol based on probabilistic coverage for wireless sensor networks

Abstract

Coverage control in high dense wireless sensor network is an important way to make the network more efficient, which can schedule the sensors in active or sleeping state at the right time on the precondition of maintaining the network coverage. Aiming to make the best of redundant coverage of the high dense network, an area control protocol based on probabilistic coverage model is designed. To simplify the area coverage judgment, the area coverage problem is transformed into the several points coverage judgment, an area judging rule is presented base on the previous work. And then, using the promoted judging rule, a node self-schedule scheme is designed, which can turn the sensor into active state or sleep according to the information received from its active neighbors. Comparing with other coverage control protocol, our promoted protocol can maintain the network coverage quality and prolong the network lifetime more efficiently.
