摘要:

针对室内环境下WLAN网络中选点不合理、AP干扰大等问题进行网络优化研究。总结了几种常见的室内电磁波传播模型,研究了信道分配算法—遗传算法,并在遗传算法的选择操作步骤中引入精英机制,仿真结果表明,其收敛速度更快,可提高智能计算速度。采用精英机制可比传统的轮盘法提高79.3%的速度。

Abstract:

The optimization of WLAN network is proposed to solve the problem of the unreasonable point selection of strong interference in indoor environment. This paper summarizes several common propagation models in WLAN network and presents the genetic algorithm in channel allocation, respectively. Then this paper gives a simulation of the algorithm and introduces the elite mechanism during the operation steps, which is capable of faster convergence and intelligent computing. The use of elite mechanism improves the speed by 79.3% over the traditional roulette method.

Key words: WLAN, AP, channel allocation, genetic algorithm, elite mechanism
