摘要
介绍了Ad Hoc网络中保障实时业务QoS要求的时间同步多址接入协议。该类协议以时分多址为基础,通过资源预留为实时业务预约固定的时隙,赋予实时业务接入信道的优先权,保证了实时业务的接入延时,延时抖动以及吞吐量等QoS指标,为Ad Hoc网络支持多媒体业务的接入奠定了基础。
This paper introduces some synchronous multiple access control protocols which guarantee the QoS requirements of real - time traffic in Ad Hoc networks. Based on time division multiple access, these protocols reserve a fixed timeslot for real - time traffic by resource reservation, and give the priority to access chan- nel for real - time traffic. Thus the access delay and delay dithering of real - time traffic are reduced and the QoS requirements of real -time traffic are guaranteed. This lay the foundation for Ad Hoc networks to provide multimedia traffic.
