摘要
随着消费电子、计算机、通讯一体化趋势日见明显,智能化信息家电产品己经开
始步入社会和家庭。在这种趋势的推动下,家庭网络技术也在不断的向前发展。家庭
媒体网关是整个家庭网络的核心设备,通过家庭媒体网关连接各种信息终端,提供集
成的话音、数据、多媒体、控制和管理等功能。在多个家庭媒体网关之间,可以通过
网络实现互连达到资源共享的目的。而无线局域网络由于其无线特性,相对于繁琐的
有线网络更容易扩展,逐渐得到广泛的使用。
本文正是基于无线局域网的优点采用无线分布式系统的方式实现家庭媒体网关
之间的互连。本文首先介绍了家庭媒体网络的应用及家庭媒体网关的相关协议和技
术,然后详细分析了无线局域网中无线分布式系统的几种实现方式。在点对点模式,
点对多点桥接模式和点对多点中继模式等几种常用的无线分布式系统实现方式的基
础上,本文设计了一种通过网关自动检测实现的点对多点的自动模式的无线分布式系
统,并详细描述了该无线分布式系统的具体实现过程。同时,本文在无线分布式系统
的基础上实现了家庭媒体网关互联的网络参数配置的自动配置。最后本文设计了网络
拓扑在家庭媒体网关间进行功能测试,测试结果表明设计的无线分布式系统可以实现
网关之间以及与外部公网的互连,符合应用需求。
本文设计实现的家庭网关无线互联的方案具有通用性、易操作性、稳定性等特点,
对家庭网关间的互联的设计与实现有一定的参考价值。

Abstract
The intelligent electric appliances have been produced and have joined in the social
lives with the integration trend of the consumer electronics, computer and the
communication. Consequentially, the work technology is progressing
residential media gateway is the core part of the whole work. It
provides integrate voices, data and media information and also the functions of control and
administration by connecting various information terminations. The information can be
shared and transmitted absolutely among the residential interior terminations and the
. Among the several residential media gateways, the resources can be shared by the
work or the wireless local work. But the wireless local work is
more convenient to extend owing to its pared to plex wired local
network. So, it is widely used.
Based on the advantages of the wireless local work, this thesis introduces a
wireless distribution system to implement the interconnection of the residential media
gateways. Firstly, this thesis introduces the applications of the residential work
together with the relative protocols and technologies. And then, it analyses several methods
of implementation the wireless distribution syst
