| 摘 要： | 该文提出了新的ad hoc网络媒体访问控制协议，即优先级轮换多址接入（priority rotation multiple aceess，简称PRMA）。该协议适用于单信道半双工电台。通过载波监听，并使用控制分组，PRMA有效地解决了在多跳网中的隐藏终端问题。在不同的访问周期，节点可能具有不同的优先级。为了避免冲突，节点按照优先级，在不同的时间发送分组。理论分析和仿真结果表明．PRMA协议在低负载和高高载时均有转高的吞吐量。

| Abstract: | PRMA(priority rotation multiple access),a new MAC protocol for ad hoc network,is proposed in this paper.The protocol applies to single-channel half-duplex radioes.With the help of a carrier sense and the control packets,PRMA effectively solves the hidden terminal problem in a multi-hop network.In PRMA,one node may have different priority in different access cycles.In order to avoid collistion,each node sends packets at different time in accordance with its priority.Theoretical analysis and the simulation result show that PRMA has high throughput both on the high-load and on the low-load conditions. |
