Abstract

The recent improvements in implantable medical devices combined with advanced wireless sensor networks are set to revolutionize the health-care industry by providing real-time, low-cost health monitoring for the patients. A new-field called Implantable Wireless Body Sensor Networks (IWBSN) has become a hot research topic because of its energy constraints and complex design. The main components of IWBSN are the base-station and implantable sensor nodes. The most important challenge is designing the sensor nodes which has to stay inside the body for long time. A novel protocol called ``Time-Based Coded Data" (TBCD) was formed in an attempt to reduce the energy consumption in the sensor nodes. While validating TBCD protocol clock drift and wireless body channel were not considered. Clock drift causes the sensor nodes to go out of synchronisation in an inconsiderable period of time. The human tissues provides a high path loss to the wireless channel.
This thesis proposes an error compensation method for both delay and clock drift. This helps the base-station and sensor nodes to stay synchronised for a longer period of time. The thesis also proposes a verification framework work which focusses on providing realistic situations to validate ultra low power IWBSNs. This framework enables to prove the functionality of TBCD protocol with delay and drift calculation and enables 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 of sensor nodes using TBCD protocol is greater when compared to the state-of-art protocols.
