Abstract

In this paper, we study the joint impact of task priority and transmission time slot variable computing services on a novel p-persistent random multiple access communication protocol (p-persistent CSMA) in an edge server network. The traditional p-persistent CSMA protocol performs better at low loads, and in order to make the protocol perform better even when the edge server network is accessed by a large number of smart terminals, we consider adding a variable success time slot length and a multichannel, multipriority access model. When the success time slot is longer, the nodes will take longer time to send data, which will reduce the number of nodes retransmitting data, thus improving channel utilization and making the throughput rate of the network increase accordingly. Then, different priority levels are assigned according to the user’s needs, and the higher the priority level, the more channels are occupied and the probability of successful message delivery increases. Finally, the superiority of the proposed protocol is verified by simulation.

用于边缘服务器部署的新的多优先级和可变持续时间三时隙P-CSMA协议

本文研究了任务优先级和传输时隙可变计算服务对边缘服务器网络中p-persistent随机多址通信协议(p-persistent CSMA)的联合影响。传统的p-persistent CSMA协议在低负载下性能更好，为了使协议在边缘服务器网络被大量智能终端接入时也能有更好的性能，我们考虑增加可变成功时隙长度和多通道、多优先级的接入模型。当成功时隙越长，节点发送数据所需的时间就越长，这将减少重传数据的节点数量，从而提高信道利用率，使网络的吞吐率相应提高。然后，根据用户的需求分配不同的优先级，优先级越高，占用的通道越多，消息传递成功的概率也就越大。最后，通过仿真验证了该协议的优越性。
