Abstract: Along with researches to Ad Hoc networks deeply，Quality of Service（QoS） has became one of the hot topic at present.To providing backup to QoS in the special network of ad hoc，designing an effective admission control algorithm aiming at flow is necessarily.By analyzing the characteristics of wireless channel，this paper solves the key problems of implement admission control，and base on that it proposes a QoS-based distributed admission control algorithm.Simulation experiments show that，by applying the admission control algorithm to traditional routing protocols（such as AODV），the performance of the protocol improves a lot，and it adapts to the transmission of real-time traffic better.
