The need for a telemetry system arises due to the </em><em>increasing desire to simultaneously monitor, measure and record critical data of patients located </em><em>in different places at optimal cost. Toward this end, a wireless telemetry system was designed </em><em>and implemented, especially for small-scale medical applications, particularly, for proper </em><em>monitoring of the heart-rates of mostly elderly patients. In order to enhance the capabilities of </em><em>the system, an infrared-based pulse Oximeter sensor was designed and integrated into the </em><em>telemetry system, and this sends the acquired data to an Arduino microcontroller for preprocessing. The controller sends the pre-processed data to a coordinator PC over a ZigBee mesh </em><em>wireless network, via a graphical user interface (GUI). For seamless transfer of data from source </em><em>to destination, a source routing algorithm was applied to route the desired data over the </em><em>proposed ZigBee network. Thus, an optimized source routing algorithm was evolved, and applied </em><em>to the telemetry system in order to lower the latency of data transmission of the nodes over the </em><em>wireless network. Finally, the performance of the optimized routing algorithm was compared with </em><em>the existing source routing algorithm, and the wired telemetry system. Results show that data </em><em>routing through the wired telemetry has much lower latency among the investigated routing </em><em>schemes, and the optimized source routing algorithm transmits data with substantial gains in </em><em>throughput, and achieved average latency about half the latency of the source routing algorithm.</em></p>}, number={2}, journal={International Journal of Electrical Engineering and Applied Sciences (IJEEAS)}, author={Imoize, Agbotiname Lucky and Orodeji, Oluwasegun Oluwatobi}, year={2020}, month={Oct.} }
