把地理区域分成一个个小区，蜂窝系统在该区域内提供无线覆盖。把可用的频谱分成很多信道，每个小区分配一组信道。使用频分双工（FDD）。在小区间进行频率利用，N个小区构成一个簇，簇间进行频率复用。定义了传播特性（信道参数）以及同频小区的位置。信道的参数包括：小区半径，路径损耗指数，以分贝为单位的对数正态阴影的标准差，基站发射功率级，移动台发射功率级，每个小区的扇区数，扇区化天线的正反向比，要仿真的瞬时位置的组数，同频干扰阈值。-To a geographical area is divided int

We proposed a efficient sector power control based on
distance between base station and mobile node. Also we proposed a
sleep mode energy control mechanism. In sleep mode energy saving
protocol, each sector monitors the number of user in sector

Each sector monitors the number of user in sector cell. If
number of mobile node falls down a given threshold in sector
cell, base station shuts down power. Controlling base station
power can reduce power consumption of base station
