大规模组网的集中式基站休眠算法
A base station sleep algorithm for large-scale centralized networks
摘要
Abstract
The principle and performance of the centralized base station (BS) sleeping algorithm and the distributed BS sleeping algorithm for reducing the energy consumption of wireless communication networks were analyzed , and then, a centralized clusting algorithm ( CCA) for BS sleeping was proposed for large scale wireless communication networks to solve the problem that the computational complexity of the centralized algorithm will become very large when the number of BSs increases .The CCA first formulates a bi-objective problem to divide the sleep period , and then the BSs are divided in clusters to obtain the combination of BSs ’ states through the particle swarm optimization ( PSO) .The simulation results show that the CCA significant outperforms the PSO and fast exhaustive algorithms in the computational complexity while keeping the same performance in energy saving as these algorithms ’ .关键词
