Abstract
These days, healthcare services are enjoying the application of pervasive computing systems. Advances in wireless technologies— such as intelligent mobile devices and wearable networks can improve communication among patients, physicians, and other healthcare workers as well as enable the delivery of accurate medical information anytime anywhere, thereby reducing errors and improving access. However, transmission of vital signs, frequency of transmission of vital signs, network communication cost, context refinement, and management of large contexts are still problems of pervasive healthcare systems. In this work, we propose a context aware pervasive healthcare system for HIV/AIDS (Human Immunodeficiency Virus/ Acquired Immunodeficiency Syndrome) patients (CAPHS). The architecture of the system consists of three constituents: the patient unit, the healthcare unit and the doctor/nurse unit. The patient unit consists of a group of body sensors for detecting vital signs data from patients and transmitting it to the patient‘s smart phone via Bluetooth. After preprocessing, the smart phone transmits vital signs context information to the healthcare unit via Internet for further processing and reasoning if there is any abnormality. This preprocessing helps to determine the frequency of transmission of vital signs and reduces the network communication cost to transmit vital sign data. At the same time, it also increases the efficiency of the healthcare unit because this operation reduces its task of context refinement. The healthcare unit is rich in ART (Antiretroviral Therapy) ontology knowledge that we developed. For better management of large contexts, we use a hybrid context management approach in which the high level schema ontology stored in OWL/RDF (Web Ontology Language/Resource Description Framework) format and the ontology instances stored in ordinary relational database. The doctor/nurse unit is the thinnest of all units in terms of number of components. It communicates with the healthcare unit via Internet/SMS so that physicians can remotely monitor their patient. We have developed a prototype implementation for the system and we see that it is promising.
