摘　　要：为减少无线蜂窝网络的能量消耗,提出一种非对称覆盖补偿方法。将休眠小区覆盖区域划分成若干小区域;利用基于小区域块划分的覆盖补偿算法,给周围的基站合理分配小区域块,达到该补偿的目的。该算法能够有效减少蜂窝网络的能耗,使周围基站的覆盖增量能耗最小。仿真结果表明,该算法不仅可以减少基站覆盖增量能耗,相比其它覆盖策略具有更好的阻塞率表现。To reduce the energy consumption of the cellular network, an asymmetric coverage compensation method was pro- posed. The coverage of the sleeping base station was divided into several small blocks. A small blocks based coverage compensa- tion algorithm was used, and those small area blocks were distributed properly to the surrounding base station for coverage com- pensation. This algorithm can reduce the energy consumption of the cellular network and optimize the incremental energy con- sumption of the surrounding base stations to the minimum. The simulation was presented to verify. Results of verification show this method can not only reduce the energy consumption of the network, but performs better in the blocking rate than other co- verage compensation methods.
