A Study on Wearable Sensor Networks for Healthcare
Abstract
Wireless body area networks (WBANs) are emerging as important networks, applicable in various fields. The network typically extends over the whole human body and the nodes are connected through a wireless communication channel. WBAN consists of sensors, transceivers, battery, processors and accerelerometer. WBANs can be seen as a special purpose sensor networks designed to satisfy Quality of Service (QoS) requirements of physiological signals operating in different environments. This paper surveys the WBANs that are designed for applications in healthcare. We present a comprehensive survey consisting of stand-alone sections focusing on important aspects of WBANs. We examine the following: monitoring and sensing, power efficient protocols, system architectures. We conclude by discussing some open research issues, their potential solutions and future trends.
