User-dependent perfect-scheduling QoS support for wireless mobile ad hoc networks
移动分布式无线网络中具有QoS保证的UPMA协议

Based on the concept of contention reservation access and polling transmission, User-dependent Perfect-scheduling Multiple Access (UPMA) protocol for supporting node mobility, multihop architecture and quality-of-scrvice (QoS) of multimedia traffic is proposed. It improves channel utilization greatly and guarantees a node to access channel rapidly. Moreover, it provides QoS guarantees for real-time traffic. Finally, the network performance of Internet data traffic is simulated and related conclusions are given.
