Internet of things healthcare cloud system based on IEEE 802.15.4

Abstract

Recently researchers are spending great efforts on the wireless Body Sensor Network (BSN) for medical applications such as monitoring of heart beats, body temperature, blood pressure, pulse of the aging people both in hospital or at home. The combination of BSN and mobile communications and cloud comuting makes medical applications for a large population possible. In this paper, based on the CSMA/CA protocol, a kind of adaptive binary backoff algorithm is proposed and applied to the internet-based healthcare cloud systems, which enables longer survivability time of BSN than binary backoff algorithm. Simulation results are included to illustrate the effectiveness of the proposed control scheme. Moreover this algorithm implemented in this Internet of things health care cloud system. © 2013 Asian Network for Scientific Information.
