摘要: 该文针对无线传感器网络的覆盖性和连通性问题，在假设传感器节点地理位置信息已知的条件下，设计了一种包含全连通群的建立和维护以及群内节点休眠调度的全新算法。该算法采用保证群内节点彼此一跳可达的全连通群分群方法，以及分布式节能的休眠调度策略，最大程度上减少传感器网络的能量消耗，延长了网络寿命。仿真结果表明：该算法能较好地保证无线传感器网络的覆盖性和连通性，且能耗较低。Abstract: Aiming at the issue of sensing coverage and connectivity in wireless sensor networks, A complete new algorithm is proposed, on the premise of sensors position aware. The algorithm adopts a clustering method and a decentralized sleeping method to reduce the energy consumption of wireless sensor networks and to prolong the lifetime of wireless sensor networks. The fully connected clustering method ensures that all sensors in a cluster can communicate with each other within one hop. The result of simulation indicates that the algorithm can maintain sensing coverage and connectivity in wireless sensor networks, while the energy consumption of sensor networks is small.
