Simulation And Realization Of Wireless Emergency Communication System Of Digital Mine

The key question of underwell disaster rescue is that the information of disaster place can not be collected and transported to the rescue base for the failure of normal communication equipment . A new wireless emergency communication has been introduced in this paper that a temporary wireless channel has been putted with repeaters of Wi-Fi ,the Wi-Fi end equipment with sensors to be treated as disaster place information collecters,then the disaster information can be transported with it.The wireless emergency communication system has been simulated used NS2. The result shows that the system performs well on delay time , jitter and stability. And it is suitable for the requirement of emergency communication after underwell disaster.
