IEEE802.11中的位置管理

无线局域网是将Internet技术和移动通信技术相结合实现"最后一公里"的重要手段之一.本文提出了无线局域网中的四种位置管理策略,并就无线局域网中分布式系统分别采取有线介质和无线介质的情况,对四种位置管理策略加以比较.性能分析结果表明:针对有线分布式系统,策略a和d是较好的方法;针对无线分布式系统,策略d是较好的方法.

In this paper,the formulae are indicated firstly to design artificial reverberator.After analyzing the properties of two reverberators,a connection in series all-pass reverberation system has been addressed in detail.This system is designed based on the artificial reverberation formulae,as well as the operation complexity.The simulation of echo density,which is the crucial reverberation factor,is analyzed.At last,the principles to design the system parameters and the solution to reckon the reverberation time are proposed.Experimental results confirmed that not only coloration and flutter had been eliminated completely but also the echo density is consistent to the room acoustics,and the natural reverberation effect could be simulated vividly.
