Ad Hoc网络拓扑与隐藏终端/暴露终端的研究

Ad Hoc NeTwork Topology and Hidden/by Exposed Terminal Problems

文中介绍了ad hoc网络的概念,分析了其信道共享方式。从而,引出由于ad hoc信道共享方式的不同而导致的隐藏终端和暴露终端的问题。文章通过对网络拓扑的研究,列出了三种基本的网络拓扑结构:全连接、星型和线性结构。并且通过矩阵可以表示这些拓扑结构特征。对于三种不同的拓扑结构,不同的拓扑结构结合相应的技术可以更好地解决隐藏终端和暴露终端带来的问题。

This paper first describes the concept of ad hoc network and analyzes the way of channel sharing thus leading to the hidden, exposed terminal problems in ad hoc network. This paper lists three kinds of basic topology： full-joint, star-shaped and line-shaped structures, which are expressed by matrix. With the different topologres, appropriate technologies have been taken to solve the hidden, exposed terminal problems of three kinds of basal topology and special ways.
