摘要 时变链路和节点移动的无规则性是移动 Ad- Hoc网络 ( MANET)服务质量 ( Qo S)保障问题未能得以解决的关键原因 .本文基于自适应 Qo S结构框架 ( MAQF) ,通过对 MACA/ PR介质访问控制协议进行改进 ,提出了一种新的自适应 Qo S介质访问控制策略 ( MAQF/ MAC) .它具有链路测试及动态资源调整等功能 .仿真结果表明 ,MAQF/ MAC在资源利用率及基本 Qo S保障能力等方面均优于 MACA/ Based on MAQF (MANET Adaptive QoS Framework) and through modifying the protocol of MACA/PR, a new mechanism MAQF/MAC that can provide MAC QoS guarantees for MANET was presented. Link testing and dynamic resource adaptation are the two features of MAQF/MAC. The simulation results show that MAQF/MAC has more efficient resource utility and better QoS measures than MACA/PR.
