Quality of information for wireless body area networks

Abstract

The Wireless Body Area Networks (WBANs) are a specific group of Wireless Sensor Networks (WSNs) that are used to establish patient monitoring systems which facilitate remote sensing of patients over a long period of time. In this type of system, there is possibility that the information accessible to the health expert at the end point may divert from the original information generated. In some cases, these variations may cause an expert to make a diverse decision from what would have been made specified to the original data. The proposed work contributes toward overcoming this foremost difficulty by defining a quality of information (QoI) metric that helps to preserve the required information. In this paper, we analytically model the QoI as reliability of data generation and reliability of data transfer in WBAN.
