基于相对局部密度的三维节点调度算法
Node-based relative local density scheduling algorithm for three-dimensional wireless sensor networks
摘要
Abstract
In node scheduling algorithms in the back off dormancy process of redundant nodes, high energy consumption is the problem to be addressed at present. A three-dimensional node scheduling method on the basis of relative local density is proposed in this paper. The algorithm defines the concept of relative local density of nodes. It firstly determines whether a node is redundant according to the principle of redundancy, then puts the redundant node to sleep in the form of probabi-listic competition according to residual energy and relative local density of the nodes, and thus avoids the energy consump-tion of node back off dormancy. Simulation shows that the three-dimensional node scheduling method on the basis of rela-tive local density, under the premise of meeting the specified coverage, can reduce the energy consumption of nodes and prolong the lifetime of network.关键词
