Load control scheme to preserve processing capacity for emergency biometric data

Abstract

A significant increase in ageing population is seen in past ten years. Recent advances in wireless sensor networks and wireless body area networks have paved the way for remote health monitoring. With remote health monitoring devices, patients and caretakers are enabled to keep track of patient's health status each second and provide immediate treatment to the patient in case of any emergency. Reliability of such devices is a big concern as any delay or drop of biometric data transmission can put patient's life at risk. In this paper, we propose a load control scheme to provide reliable communications for emergency data. Thanks to reserved capacities for emergency data in the proposal, the packet dropping probability for emergency data is much lower than the no load control scheme.
