摘要： 针对Ad Hoc网络中的服务质量(QoS)保障问题，提出按需QoS路由算法DQR。该算法通过有限洪泛的方式进行寻路，并在路径的每个中间节点实行准入控制、动态可调节性的资源预留/资源释放，采用路由序列号的方式避免回环产生。仿真结果验证，提出的QoS路由算法在流量接受率、端到端到达率、平均端到端时延等指标上均能获得较好的性能。

Abstract: Aiming at the Quality of Service(QoS) provision problem in Ad Hoc networks, this paper proposes the on-demand QoS routing algorithm called DQR, which broadcasts limited routing request packets, performs admission control in inter-media node, adaptively reserves and releases resource, uses routing sequence for loop free. Simulation results prove that the proposed algorithm gets a better performance at parameters such as traffic admission ratio, end-to-end delivery ratio, average end-to-end delay.

Key words: Ad Hoc networks, QoS provision, routing
