| 摘 要： | 提出一种基于节点物理地址为初始分配信道的动态多组异步多信道媒介访问控制协议(DMAM-MAC).在该协议中,各节点根据自己的物理地址确定初始主信道,并且与同处在一个主信道上的相邻节点构成一个信道组;随着网络运行,各节点根据自身的业务流,动态改变主信道,加入新的信道组,从而有效提高了频率空间复用度.仿真试验证明,与IEEE802.11、AM-CP相比,DMAM-MAC协议在显著提高Ad hoc网络平均吞吐量的同时,还能有效降低数据包平均延迟.

| Abstract: | A dynamic multi-group asynchronous multi-channel MAC protocol(DMAM-MAC) based on node physical address as initial distribution channel is presented in this paper.In this protocol,Each node according to their physical address determine the main channel firstly,and form a channel group with the adjacent nodes having the same main channel;With the operation of the network,each node in accordance with its own traffic,dynamically changes its main channel,and joins a new channel group,so as to effectively improve... |
