Abstract : Advancement in wireless technologies to improve telemedicine is one of the major goals in recent times. Wireless telemedicine for emergency primary healthcare is a technology which provides mobile healthcare and exchange of medical data from ambulances or rural healthcare centers to hospitals. This helps the hospitals to understand patients' medical condition before they arrive. The idea is to be prepared in advance for hospitals to respond to such cases. This work focuses on creating a vehicular ad hoc network scenario for telemedicine, where an attempt is made to identify an optimal solution using 802.11 networking standard. A vehicle-to-vehicle connection is created which has been evaluated using various node densities by choosing 802.11n, 802.11p and 802.11b with AODV (Ad-Hoc On demand Distance Vector) routing protocol. Constant bit-rate traffic is used between the ambulance and hospital. Validations for the standards are carried out for the parameters PLR (Packet Loss Ratio), delay and throughput considering blood pressure, video and audio transmission. The performance results are analyzed for all three standards based on mobility and varying vehicular speeds. We have compared the results of various parameters for each scenario and attempted to identify the better performing standard. NS3 has been used for simulation in networks, whereas for traffic simulation SUMO (Simulation of Urban Mobility) is used.
