Abstract 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-service (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.
