Abstract: The advancements in wireless communication and sensor technology have grown significantly in the recent years particularly in medical applications. Existing health care systems do not provide real-time monitoring of the patient's health condition. To overcome this limitation, Wireless Body Area Networks(WBANs) have been introduced. WBAN allows for mobility of patients due to its portability and location independent monitoring. We propose the design and implementation of a Wireless Body Area Network for a patient in an ambulance to obtain the vital parameters namely ECG signal, Blood pressure, Temperature etc., from the patient's body using appropriate sensors and transmit them to the WBAN co-ordinator. The WBAN co-ordinator sends the information to a GSM module. This information can be communicated to a doctor/expert to provide continuous treatment before the patient in the critical state reaches the hospital. The collected information will be maintained in a database to be extracted by the people/expert anytime and anywhere using suitable Android application. We also analyze the effect of path loss associated with the signal transmission due to varying position of the nodes. The impact of pathloss on energy consumption of the nodes is also analyzed in this work.
