摘要
为了满足高动态终端对接入时延的需求,设计了一种带有优先级的随机预约/按需分配相结合的MAC协议RRDAMA-P(random reserve/demand assignment multiple access protocol with priority),同时结合排队理论推导了高低两种优先级节点的平均时延近似表达式。利用OPNET软件验证了RRDAMA-P协议的有效性,结果表明RRDAMA-P协议不仅可以满足不同终端的优先级要求,而且实现了更好的时延性能。
This paper proposed a MAC protocol named random reserve/demand assignment multiple access protocol with prio-rity according to different time delay demands of different speed terminal.It gave the average end to end（ETE） delay formulates of different priority nodes using the queue theory.Then established a simulation model with OPNET software.The results reflect that the RRDAMA-P protocol meet the different demand of different priority terminals and achieve better time delay performance.
