Remote Healthcare Monitoring System Architecture using Sensor Networks

Ubiquitous processing is impacting several applications affecting our lives. In this paper we propose a remote health care monitoring system that uses sensor networks to extend the coverage of medical application to underserved area. We delineate the challenges that face researchers in this area. In addition, the paper describes the general architecture and proposes a MAC scheme for healthcare sensor networks (MACH) that adapts channel provisioning based on the information criticality. MACH enables emergency traffic to meet its quality of service (QoS) requirements. Performance evaluation using analytical modeling shows that our proposed MAC give preference to emergency traffic which is crucial for medical applications.
