摘要
Ad hoc网络是一种特殊的对等式网络。传统的基于固定的或有中心的网络的协议不能满足 Ad hoc网络的需要。首先研究了 Ad hoc网络信道接入协议要考虑的隐终端问题和暴露终端问题 ,并给出了一种可能的双信道解决方案。在分析了现有的两种退避算法后 ,提出使用退避计数器广播加信道争用估计技术来消除不公平现象。在这些结果的基础上 ,提出了一种新的信道接入协议。
Ad hoc network is a kind of special peer-to-peer network.Those custom protocols based on fixed or centralized network can't be used by Ad hoc network.First,this paper analyzes the hidden terminal problem and exposed terminal problem and proposes one possible dual channel method.After the analysis of two current backoff algorithms,the author describes the method to get rid of the unfairness by using backoff counter advertisement and channel contention estimation.Based on these results,the author presents a new channel access protocol
