Wireless sensor network implementation for mobile patient

Recent advances in embedded computing systems have led to the emergence of wireless sensor networks (SNETs), consisting of small, battery-powered “motes” with limited computation and radio communication capabilities. SNETs permit data gathering and computation to be deeply embedded in the physical environment. Large-scale ad hoc sensor networks (ASNET) can provide dynamic data query architecture to allow the medical specialists to monitor patients remotely via (PDAs) or cellular phones. A three-layered architecture is proposed where sensors, microcontrollers, and central server/handhelds occupy the lower, middle, and top layers, respectively. The implemented network distinguishes between periodic sensor readings and critical where higher priority is given for the latter. In this paper we implement 3 special cases for tracking and monitoring patients and doctors using SNETs. Finally, the performance of a large scale of our implementation has been tested by means of simulations.
