摘要
提出一种基于多目标遗传优化的节能覆盖方法.以节点不同开启顺序建立个体基因组,采用双交叉保留优秀个体,在保证覆盖度的同时,开启尽可能少的节点.本方法延长了网络生命期,均衡了网络中各节点能耗,同D-Greedy及DCS-dist等方法相比,也表现出了较好的性能.
An energy-saving coverage scheme is proposed based on multi-objective genetic algorithms. Genomes are estab- lished according to the different opening sequences of nodes and the outstanding individuals are preserved due to the double cross operation which could open as line as possible nodes when meeting certain network coverage requirement. This method could ex- tend the network life, and balance the network energy consumption. It obtains satisfactory performance compared to D-Greedy and DCS-dist methods.
