Development of Mobile Ad Hoc Network for Emergency Telemedicine Service in Disaster Areas

Emergency Telemedicine Service (ETS) is used efficiently for treatment to the wound patient in disaster areas. However, ETS cannot be used if the primary network channel is unavailable due to unexpected damages on the communication infrastructures, and increased network traffics. We established the Mobile Ad hoc Network (MANET) based on Wireless LAN (WLAN), and developed software program implemented with the Ad hoc On-Demand Distance Vector Routing Algorithm. The results of experiment are shown that a Mobile Node (MN) in disaster areas provided the sufficient network bandwidth for ETS using MANET. Therefore, MANET is able to provide the ETS by supple configuring the secondary channel in disaster areas where the primary network channel is unavailable.
