摘要
针对Ad hoc网络的多信道隐藏终端问题,提出一种基于邻居节点合作通告机制的异步多信道媒介访问控制协议。该协议通过空闲邻居节点向未收到信道协商控制帧的节点发送通告广播帧,从而有效地解决了多信道隐藏终端问题。仿真结果表明,与IEEE 802.11、MMAC协议相比,该协议在提高网络平均吞吐量的同时,还能降低数据包平均延迟。
Aiming at the multi-channel hidden terminal problem in Ad hoc networks, this paper presents an asynchronous multi-channel Medium Access Control(MAC) protocol based on neighbor node cooperation announcement mechanism. In this protocol, the idle neighbor node sends an announcement broadcast frame to the nodes which have not received channel consultation control frames. It can effectively solve the multi-channel hidden terminal problem. Simulation results show that, compared with the IEEE 802.11 and MMAC protocol, this protocol can improve the average throughput of the network significantly and reduce the average packet delay simultaneously.
