【摘要】：針對井下信道環(huán)境復(fù)雜、無線網(wǎng)絡(luò)連通性差的問題,提出一種基于礦下工種終端移動馬爾可夫模型的多屬性機(jī)會網(wǎng)絡(luò)分組轉(zhuǎn)發(fā)協(xié)議并實現(xiàn)。首先結(jié)合礦下終端移動建立馬爾可夫模型,預(yù)測終端相遇概率;然后計算終端網(wǎng)絡(luò)時延、終端與目的終端相遇概率及其擴(kuò)散范圍;最后根據(jù)層次分析法確定數(shù)據(jù)轉(zhuǎn)發(fā)策略。仿真結(jié)果表明,提出的分組轉(zhuǎn)發(fā)協(xié)議在終端活動范圍受限、活躍度有較大差異的場景下可以獲得更好的網(wǎng)絡(luò)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.
