摘要
该文基于有效竞争预约接入、无冲突轮询传输的思想提出了支持节点移动性、多跳网络结构和服务质量(QoS)的依据用户妥善安排的多址接入(UPMA)协议。它大大提高了信道的使用效率,保证了发送节点能快速接入信道,同时,最大程度地保证所有实时业务的时延和带宽要求。最后,我们考察了它对Internet数据业务的支持性能。
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.
