无线网络的中继节点布局优化研究

Research on Layout Optimization of Relay Nodes on Wireless Networks

中继节点的布局问题是无线网络面临的主要问题。提出了基于免疫算法的中继节点布局优化算法,同时,考虑到能效性对布局结果的影响,采用路径损耗因子F为评价标准,使得整个无线网络能量的消耗更加节省、均衡。另外,比较以最短网络路径为评价标准的传统算法和以路径损耗因子F为评价标准的优化算法的发射功率,可以得出基于路径损耗因子F为评价标准的布局算法能够有效减少整个网络的能量消耗,延长网络的生命周期。

This paper presents the layout optimization algorithm of relay node based on immune algorithm,at the same time,considering the energy-efficiency effect on the layout results,and adopts the path loss factor F as evaluation criteria,which made the energy consumption of the whole wireless network more saving and balanced.
