| 摘 要： | 针对基于TDMA（时分多址）的数据链网络协议在恶劣环境下时延大、业务突发性强等缺点,提出了一种改进的数据链协作MAC协议。在原有的协议中引入协作通信的思想,节点根据协作机制,利用自身时隙进行协作转发,并进一步加入中继优先权因子改进协作机制,中继节点根据节点的繁忙程度与信道条件来判定是否协作传输。通过对网络时延性能的研究与仿真,结果表明,改进后的协作协议性能优于传统的数据链协议。

| Abstract: | For the drawbacks of cooperative MAC protocol based on the data link network of TDMA in bad environment,such as large time delay and strong traffic burst,an improved cooperative MAC protocol for data link network is proposed.The advanced protocol leads into the thought of cooperative communication.Nodes in the network use their own slots to relay packets cooperatively and further join the modified cooperative mechanism of relayed data priority.The relay node decides whether to do cooperative transmission ac... |
