  • 摘要:A packet forwarding protocol based on terminals' Markov mobility model (TMM) is proposed for coal mine poor connectivity in opportunistic networks since its complex environment. First, a Markov model is established for predicting the probability of terminals' encounter. Then the network-delay in the condition of next selected relay-terminal (NDT), the probability of terminal encounter with destination (PTD) and the terminal diffusion range (TDR) are calculated based on the model, by which the best relay-terminal can be obtained to receive data packet based on Analytic Hierarchy Process (AHP). Theoretical analysis and simulation results show that the proposed protocol has a better performance in terms of delay and overhead compared with Flooding and HMPR method, and it's more suitable for coal mine opportunistic networks.
