Abstract

A multichannel non-persistent of P-CSMA (NP-CSMA) random multiple access ad hoc network in MAC protocol based on variable collision length is proposed. It has important applications value in wireless ad hoc network and so on. When the channel is idle, the end-users are sent by P probability; while the channel is busy, it will not listen to the channel and wait for a certain period of time to send it again. The multi-priority mechanism is introduced to meet the needs of QoS in different priorities. By modelling the new multi-priority NP-CSMA protocol, the throughput of each channel is obtained by using the average cycle method. Compared with other protocols, the superiority of this protocol is obtained, and the accuracy of the protocol is verified through simulation experiments.

MAC协议分析中非持久型随机多址自组网新型多优先级P-CSMA分析

提出了一种基于变碰撞长度MAC协议的P-CSMA (NP-CSMA)随机多址自组网多通道非持久性。在无线自组织网络等方面具有重要的应用价值。当信道空闲时，终端用户按P概率发送;当通道繁忙时，它将不会侦听该通道，并等待一定的时间来再次发送它。为了满足不同优先级的QoS需求，引入了多优先级机制。通过对新型多优先级NP-CSMA协议进行建模，利用平均周期法得到各信道的吞吐量。通过与其他协议的比较，得出了该协议的优越性，并通过仿真实验验证了该协议的准确性。
