摘要:

本文提出了一种适用于船舶通信网的无线接入协议——基于优先级的时分多址协议(PTDMA),它允许节点通过捎带预约的方式动态申请时隙,并采用基于优先级和网络负载的动态时隙分配算法分配时隙.此外,它还保证节点动态接入和退出.仿真结果表明,该协议有较好的网络性能

关键词: 船舶通信网 多址接入协议 优先级

Abstract:

A wireless access protocol of priority-based time division multiple access (PTDMA) protocol used for ship communications network is presented. The p rotocol allows a node to request slots by means of piggyback reservations, and employs a dynamic slot allocation algorithm based on priority and network load to allocate slots. Moreover it guarantees the node to access and quil dynamically, Simulation resuhs show that the PTDMA protocol has beller performance.

Key words: ship communications network, multiple access protocol, priority
