一种新的分组无线网隐终端问题解决方案

A New Solution for Hidden Terminal Problems of Packet Radio

在C -T CDMA方式中 ,最主要的问题是发送端的每次数据发送是盲目的 ,因而冲突概率很高。本文把RTS CTS短分组交换方式引入到C -T CDMA方式中 ,提出一种基于RTS CTS调度的多址方式 ,既解决了隐终端问题 ,又降低了冲突概率 。

The main problem in C-T/CDMA multihop networks is that the sender is blind before sending data everytime. In this paper, we introduce the RTS/CTS short packets to C-T/CDMA networks and propose a new multi-access method to resolve the hidden terminal problems and reduce the probabilities of the collision. So the performance of network can be improved.
