摘要： 提出一种新的Ad Hoc网络QoS保障框架。该框架能够区分不同优先级的业务和不同QoS要求的业务。能够保障在网络可用资源不足的情况下，高优先级的业务通过“抢占”的方式接入网络，而同时保障低优先级的业务使用网络资源的最低容限。仿真显示该框架具有区分业务优先级和保障业务不同QoS要求的能力。

Abstract: This paper presents a QoS architecture for tactical Ad Hoc networks. The QoS architecture can differentiate traffics with different priority and different QoS demand. When there are not enough resources in the network, traffics with high priority can access network through “preemption”. This architecture also guarantees traffics with low priority to use network resources fairly. Simulation results show that this QoS architecture can satisfy traffics with different priority’s Qos demand.

Key words: Ad Hoc network, priority, QoS
