Abstract:

According to the too high density of nodes in Wireless Sensor Networks(WSN) and imbalanced energy consumption of nodes, a distributed coverage control algorithm based on energy(DCCABE) is proposed. This algorithm is based on probabilistic coverage model and computes the area coverage probability of nodes to judge the redundancy according to the sequences which are arranged by the remain energy of nodes and changes the redundant nodes into sleeping state. Simulation results show that DCCABE can effectively reduce the redundancy of nodes and prolong the network lifetime.

摘要：

针对无线传感器网络中节点密度过大、节点剩余能量不均等问题，设计一种基于节点剩余能量的分布式覆盖控制算法，基于概率覆盖模型，按目标区域内节点剩余能量从小到大的顺序，依次通过计算各个节点的区域覆盖概率判定其冗余性，并使冗余节点转入休眠状态。仿真结果表明，该算法能有效降低网络中节点冗余度，延长网络生存时间。
