In view of the fixed communication facilities damaged and unable to work for the rain or snow disaster in the mountains area, the emergency communication system based on the mobile Internet of things (M-IoT) is proposed. To ensure the safety and liquidity of the rescue line and effectively deliver rescue personnel and materials, the proposed system can be used to real-time monitor the bridge collapse, the landslide and the dammed lake. At first, the network construction of the proposed M-IoT is described in detail. Then, this question, how to realize the effective transmission of sensing information in mountain disaster emergency communication system, is discussed. Finally, the network performance is gotten by OPNET software establishing simulation model. The results show that the proposed system has strong ability of network information transmission and can meet the demand of mountain disaster emergency communication support.
