【摘要】:针对井下信道环境复杂、无线网络连通性差的问题,提出一种基于矿下工种终端移动马尔可夫模型的多属性机会网络分组转发协议并实现。首先结合矿下终端移动建立马尔可夫模型,预测终端相遇概率;然后计算终端网络时延、终端与目的终端相遇概率及其扩散范围;最后根据层次分析法确定数据转发策略。仿真结果表明,提出的分组转发协议在终端活动范围受限、活跃度有较大差异的场景下可以获得更好的网络性能。
[Abstract]:Aiming at the problem of complex underground channel environment and poor connectivity of wireless network, In this paper, a multi-attribute opportunity network packet forwarding protocol based on the mobile Markov model of mining terminal is proposed and implemented. Firstly, a Markov model is established to predict the terminal encounter probability, and then the terminal network delay is calculated. Finally, according to the analytic hierarchy process (AHP), the data forwarding strategy is determined. The simulation results show that the proposed packet forwarding protocol is limited in the terminal activity range. Better network performance can be achieved in scenarios where the degree of activity varies greatly.
