Performance analysis of TBCD protocol over Wireless Body channel

The improvements in implantable medical devices combined with wireless sensor networks are set to revolutionize the healthcare industry by providing real-time, low-cost health monitoring for the patients. The new field called Implantable Wireless Body Sensor Networks (IWBSN) has become a hot research topic because of the energy constraints and the circuit complexity. A novel protocol called Time-Based Coded Data (TBCD) has been proposed in an attempt to reduce the energy consumption in IWBSNs. In this work, TBCD protocol has been modeled and analyzed in MATLAB/SIMULINK with realistic body channel. The goal is to find the optimum transmit power, sensitivity of the transceiver for TBCD protocol to work efficiently for an optimal distance between sensor nodes and the base-station. In addition, it has been proved that the life time of the battery (20 mAhr /3.3V Battery) of a sensor node using TBCD protocol can be prolonged to 2500 days when compared to the state-of-art Zigbee protocol.
