摘要

对于无线局域网的信号不仅希望在工作区域内覆盖良好，提供高速的接入服务，同时在工作区域以外希望信号迅速衰减，以避免通信内容被非法窃听等安全隐患，为此本文提出了一种基于智能天线的WLAN无线信号覆盖控制方法，首先设置区域内、区域边界、区域外三类传感器以及其接收信号场强的权值和目标值，利用粒子群优化算法，调整带智能天线的WLAN AP的波束组合和发射功率，从而达到使区域内信号场强最大、区域边界信号场强可接受、区域外信号场强最小的无线信号覆盖控制目的.通过仿真和原型平台验证，该控制方法达到了较好的覆盖控制效果.

Abstract

WLAN signal is not only hoped to be strong enough in work area

but also to be attenuated rapidly in no-work area

so content of WLAN signal cannot be intercepted illegally.This paper proposes a novelty solution of a smart antenna based WLAN Wireless Signal Coverage Control.Firstly deploying three kinds of sensor

including Inter Sensor

Edge Sensor

Outer Sensor.Initializing object values of weight value and received RSSI.Then through the Particle Swarm Optimizer

combinations of beam and Tx powers of WLAN APs with smart antenna will be determined

so that the wireless signals are the strongest in inter work area

are acceptable on the boundary of work area and the weakest in no work area.Simulations and experiments over a prototype demonstrate that the solution achieved significantly the destination of WLAN wireless signal coverage control.
