Distance optimization based coverage control algorithm in mobile sensor network

Coverage control is a basic research problem in wireless sensor networks (WSNs). This paper proposes a distance optimization based coverage control algorithm, which utilizes ant colony algorithm to place sensor nodes to an appropriate position and optimize the moving path of mobile sensor nodes. The proposed algorithm not only guarantees the biggest coverage of wireless sensor networks, but also reduces node moving distance, which saves sensor node energy and prolongs the entire network lifetime. Simulation results prove its validity.
