摘要

在本文中,我们考虑了蜂窝网络中的节能覆盖规划。为了节省能源,每个基站可以在其覆盖范围内没有用户或用户可以由相邻基站服务时以休眠模式工作。随着覆盖重叠的增加,在单位面积的广播电台数量和活动基站的比例之间存在权衡。给出了不同bs间距离下的覆盖规划方案的解析和数值评价方法。评估结果表明,与最小覆盖重叠方案相比,最优规划方案可使网络能耗降低20%以上,性能提升程度取决于用户密度、网络拓扑结构和休眠模式功耗。

Energy efficient coverage planning in cellular networks with sleep mode
In this paper, we consider energy efficient coverage planning in cellular networks. To save energy, each base station (BS) can work in sleep mode when there is no user in its coverage or the users can be served by neighbor base stations. With increasing coverage overlap, there is a tradeoff between the number of BSs per unit area and the proportion of active base stations. Analytical and numerical methods are presented to evaluate coverage planning schemes with different inter-BS distance. Evaluation results show that compared with the minimum coverage overlap scheme, the optimal planning scheme can reduce the network energy consumption by more than 20%, and the performance improvement depends on the user density, network topology, and the power consumption of sleep mode.
