摘要
Adhoc网络将成为未来网络体系的基本组成部分,其关键问题和研究的重点是信道接入协议的设计。而扩频通信技术因其具有频带利用率高、抗干扰能力强等特点,被确认为移动通信系统首选的多址接入方式。鉴于此,本文介绍了扩频技术、Adhoc网络以及其所面临的问题,对几种能有效解决Adhoc网络存在的问题的扩频多址接入控制协议进行了分析比较,给出了研究过程中得出的结论。
Ad hoc networks are expected to be an essential part in the future network architecture. It is, therefore, important to design its special MAC protocol. It is universally acknowledged that the spread spectrum technology is the chief multiple access mode for the mobile communication networks, due to its high channel utilization, anti-jamming, etc. On this condition, the characters of spread spectrum technology, Ad hoc networks and the problems facing it are introduced in this paper. Then several spread spectrum MAC protocols which can effectively solve problems existing in Ad hoc networks are compared with the conclusions presented at the end of this paper.
