自组网体系结构研究

Ｃ Ｓ Ｃ Ｗ 系统目标是允许用户在任何地点，在任何时间可以方便地进行群体间的协同工作。目前大多数的 Ｃ Ｓ Ｃ Ｗ 用户都需要依靠现有的网络基础设施。自组网是一组带有无线收发装置的移动节点组成的一个多跳的临时性的自治系统。在这种环境中，由于节点无线通信覆盖范围的有限性，需要借助其他中间节点进行分组转发到达信宿。它可以在没有可用的网络基础设施的情况下提供一种通信支撑环境，从而拓宽了 Ｃ Ｓ Ｃ Ｗ 的应用环境。本文描述了自组网的概念和特点，并提出了自组网的体系结构。

The Architecture of the Self organized Network

The goal of a CSCW system is to enable users to cooperate conveniently no mater when and where While,currently,most CSCW users rely on existing network infrastructures Self organized Network is a multi hop temporary autonomous system of mobile nodes equipped with wireless transmitters and receivers without the aid of any current network infrastructure In such an environment,it may be necessary for one mobile node,in order to communicate another node,to need a chain of intermediate nodes to forward packets due to the limited propagation range of each mobile node's wireless transmissions Self organized networking can provide a communication supporting environment when network infrastructures is absent,thus extending the CSCW application environment In this paper,after describing the conception and characteristics of self organized network,we propose its architecture
