Using wireless technologies for healthcare monitoring at home: A survey

The use of cable-free communications between distributed and small sensor devices in healthcare application offers many advantages to monitor people and their surrounding physical environment. In this paper we present a comparative analysis of wireless technologies for healthcare monitoring in heterogeneous Wireless Sensor Network (WSN) context. The study presents analysis on how to choose the suited technology taking into account the application requirements. The choice depends on some criteria like delay and quality of service requirements, topology, energy consumption, and other factors. This paper gives advantages and drawbacks and compares standardized and proprietary wireless technologies.
