Pervasive Healthcare Overview … A Personal

Abstract—The latest outstanding advances in mobile network technologies, wireless communications and medical sensors are propelling a new and exciting research for 21 st century pervasive healthcare systems. Such systems have the capacity to provide health services for patients regardless of time and place. The aim of this paper is to overview the state of the art pervasive healthcare technologies by exploring the conducted case studies. The paper conceptually maps the existing technologies into wearable and environmental systems with the aim of identifying, comparing and analysing the current challenges and limitations of each system. Finally, the paper concludes by shedding light on the future trends and thrusts that will direct research in this field.
