摘要
提供QoS保障是Ad Hoc网络研究的重点,而MAC协议是上层应用的服务质量能否得到最终保障的一个关键因素。详细分析在Ad Hoc网络的MAC层提供QoS保证的各种机制,针对现有的CTS/RTS资源预留方案主要基于单信道的,提出一种基于双信道的QoS资源预留方案,并使用OPNET对提出的方案进行仿真,对比双信道和单信道下的网络性能。
Providing QoS guarantee is a hot spot in Ad Hoc network research,and MAC protocol is a determinate factor of ultimate QoS provided by upper layer in protocol stack.A detailed analysis proposed on how to guarantee the quality of service at MAC layer in Ad Hoc network,and a dual-channels resource reserved scheme is given.The result of simulation proves the performance is better than that of the scheme of single channel.
