最近,由于小小区基站技术可以有效地提高系统的传输速率,其被学术界与产业界广泛关注.提出了一种在小小区基站网络中新颖的能量有效的分布式动态开关策略.本策略通过控制小小区基站的开关与服务的用户,在考虑能量有效性的同时,优化用户的数据包速率.通过系统级仿真,本算法相比两种基本算法:随机开关策略和用户与数据包接入策略,在数据包速率和单位能量消耗下的数据包速率上,具有可观的性能优势.

Recently,small cell networks have attracted much attention due to the substantial improvement on network throughput.In this paper,we propose a novel energy efficient dymamic on / off scheduling algorithm in small cell networks. The objective of the proposed algorithm is to optimize the packet throughput performance in an energy efficiency way. Compared with two exiting algorithms respectively based on random on / off and packet arrival triggered cell activation,in our system-level simulations,the proposed algorithm exhibits considerable performance gains,in terms of packet throughput per unit of energy consunption.
