This paper presents the design and implementation of the Patient Simulator, a software application used for the simulation of patient data. The simulator aims to evaluate e- Health platforms and services in regards to efficiency, reliability, security and scalability without the need to use real patient data. Using discrete event based simulation in conjunction with random normal distribution techniques, preliminary prototyping of the Patient Simulator shows that it is capable of generating five vital physiological signs including heart rate, blood pressure, body temperature, oxygen levels and respiration rate. Offline performance evaluation of the software shows that it is capable of simulating up to 10,000 patients with average CPU utilisation of 57.53% and memory usage of 159.30 MB. Future work aims to validate the accuracy of data simulated along with integrating the simulator with existing e-Health technologies to evaluate the capabilities of this software in an online environment.

Areas of Expertise

Electronic information now plays a vital role in almost every aspect of our daily lives. So the need for a secure and trustworthy online infrastructure is more important than ever. without it, not only the growth of the internet but our personal interactions and the economy itself could be at risk.
The way healthcare is delivered changes rapidly. The reasons are demographic and societal changes, austerity and rapid progressive technologies. Care models are shifting from specialist oriented hospital based to distributed, patient centred care.
