| 摘 要： | 针对传感器网络中的节点冗余问题,提出了一种冗余判别方法来关闭冗余节点,以达到延长网络生命周期的目的.首先按邻居节点的不同位置对节点进行分类,研究了每组邻居节点的网络覆盖率与工作节点数k之间的约束关系,在此基础上,按不同的冗余法则对节点进行判断,关闭冗余节点.理论分析和实验结果表明,提出的算法能关闭网络中的冗余节点从而有效地延长网络的生存时间.

| Abstract: | To solve the problem of redundant nodes in sensor networks, this paper proposes a way to determine and turn off redundant nodes in order to lengthen the network lifecycle.This paper first classifies nodes by the different locations of the neighboring nodes, and then studies the constraint relations between coverage of neighboring nodes and working nodes k in each group.On this basis, the paper determines nodes according to different redundancy rules and turns off redundant nodes.The theoretical analysis and experimental results show that the proposed algorithm can turn off redundant nodes in the network, which in turn effectively prolongs the network's lifetime. |
