摘要：
Aiming at the phenomenon that the QoS of the wireless sensor network always decreases with the running of the network, the node scheduling problem of the random deployment directional sensor network is studied. The distributed node orientation adjustment algorithm is proposed to make the network meet the coverage requirement while reducing the number of active sensor nodes, further reducing the energy consumption and improving the communication quality. In the algorithm, each node calculates its best sensing direction in a distributed manner by exchanging coverage information with adjacent nodes. Moreover, distributed redundant node scheduling for network topology reconfiguration is designed to balance the network energy consumption. Simulation results show the effectiveness of the proposed strategy. © 2016, Editorial Office of Control and Decision. All right reserved.
