A framework for enabling Patient Monitoring via mobile ad hoc network
Decision Support Systems, 2013Co-Authors: Sweta Sneha, Upkar VarshneyAbstract:A critical component of comprehensive Patient Monitoring is reliability in communication between the Patients and the healthcare professionals without any time and location dependencies. Patient Monitoring applications largely rely on infrastructure based wireless networks for signal transmission. However, infrastructure based wireless networks till date, suffer from unpredictable network coverage and have thus been attributed to the unpredictable communication reliability of Patient Monitoring applications. This research investigates an approach based on leveraging mobile ad hoc network to address the challenge of enhancing communication reliability in the context of Patient Monitoring. Mobile ad hoc network, formed among Patient Monitoring devices, has the potential of enhancing network coverage and enabling signal transmission from an area which has low or non-existent coverage from infrastructure based networks. In order to utilize mobile ad hoc network in the context of Patient Monitoring we propose (1) power management protocols that address the challenge of managing the low battery power of Patient Monitoring devices while maximizing communication reliability and (2) a framework that models the complex decision logic involved in leveraging mobile ad hoc network for diverse Patient Monitoring scenarios. Analytical evaluation of the proposed approach supports the premise that mobile ad hoc network formed among Patient Monitoring devices can enhance the reliability of signal transmission thereby improving the quality of Patient Monitoring applications. Technical and managerial implications of the research findings and the direction of future research are discussed.

Enabling ubiquitous Patient Monitoring: Model, decision protocols, opportunities and challenges
Decision Support Systems, 2009Co-Authors: Sweta Sneha, Upkar VarshneyAbstract:Healthcare costs in the US are approximately 15% of GNP and are anticipated to reach 17% of GNP in the near future. Management of chronic diseases via technology based ubiquitous Patient Monitoring services has been widely proposed as a viable option for economizing healthcare resources, and providing efficient, quality healthcare. The process of ubiquitous Patient Monitoring is information intensive, the information generated is not only fragmented but also spans multiple processes, artifacts, parameters, and decision criteria. The current study explores the complexities associated with the process of ubiquitous Patient Monitoring and the enabling technologies. The key contribution is a framework that captures the complex processes, the parameters involved, and the decision criteria for ubiquitous Patient Monitoring. The decision protocols and enabling technologies supporting the processes are detailed in the study along with the opportunities and challenges of ubiquitous Patient Monitoring. A conceptual model of ubiquitous Patient Monitoring is developed by leveraging the proposed framework and is validated by a usage scenario. Finally, the implications of future research and contributions of the current research are discussed.

A framework for supporting emergency messages in wireless Patient Monitoring
Decision Support Systems, 2008Co-Authors: Upkar VarshneyAbstract:Patient Monitoring is becoming a requirement for offering a better healthcare to an increasing number of Patients in nursing homes and hospitals. During the Monitoring, vital signs of Patients could fluctuate significantly and/or match certain undesirable patterns and therefore ''alerts'' or emergency messages must be delivered to healthcare professionals. In this paper, we address how Patient Monitoring, specifically emergency messages, can be supported over wireless ad hoc network formed among Patients' devices. The framework describes a wireless Patient Monitoring system that includes Patient Monitoring devices, routing protocols and information presentation for vitals signs and parameters. This involves a series of decisions in obtaining and processing vital signs, routing over networks, and delivering to healthcare professionals, who must make suitable medical decisions on Patients' healthcare needs. Additionally, several design enhancements to improve the quality and coverage of wireless Patient Monitoring are presented. The performance results for the proposed ad hoc network based architecture show that reliable message delivery and low Monitoring delays can be achieved by using multicast or broadcast-based routing schemes. The proposed Monitoring architecture is shown to be scalable and the cognitive load on healthcare professionals is found to be dependent on routing protocols and reliability requirement of emergency messages. The proposed work can be extended to provide personalized healthcare services to people in nursing homes, assisted living, home, and while being mobile.

Patient Monitoring using ad hoc wireless networks: reliability and power management
IEEE Communications Magazine, 2006Co-Authors: Upkar Varshney, Sweta SnehaAbstract:In the health care domain, a major challenge is how to provide better health care services to an increasing number of people using limited financial and human resources. Wireless Patient Monitoring has the potential to support these multiple and conflicting requirements. However, the current quality and reliability of Patient Monitoring have not been very satisfactory due to the unpredictable and spotty coverage of infrastructure-oriented wireless networks. Ad hoc wireless networks can be formed among mobile and wearable Patient-Monitoring devices for improving the coverage of Patient Monitoring when infrastructure-oriented networks are not accessible. In this article, we provide support for reliable wireless Patient Monitoring by presenting several protocols for power management of devices, assisted power control, and sleep strategy. The performance results show that high reliability of message delivery can be obtained while maintaining a level of power conservation.

Wireless Patient Monitoring: reliability and power management
2nd International Conference on Broadband Networks 2005., 1Co-Authors: Upkar Varshney, Sweta SnehaAbstract:Wireless and mobile technologies are finding a role in Patient Monitoring in diverse environments including hospitals and nursing homes. However, the quality and reliability of Patient Monitoring have not been highly satisfactory due to unpredictable and spotty coverage of infrastructure-oriented wireless networks such as wide-area cellular networks and wireless LANs. Recently, the use of ad hoc wireless networks among mobile and wearable devices for Patient Monitoring has been proposed. Although very exciting, there are many challenges in using ad hoc wireless networks for Patient Monitoring including how to support reliable Patient Monitoring and how to manage power transmission from Patients' devices. In this paper, we provide several solutions for enhancing the reliability of Patient Monitoring and for improving the power management of devices in normal and emergency messages transmission. We are currently evaluating the performance of the proposed solutions and protocols, and the results will be presented at the workshop

Performance evaluation of a Wireless Body Area sensor network for remote Patient Monitoring.
Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2008Co-Authors: Jamil Y. Khan, Mehmet Rasit Yuce, Farbood KaramiAbstract:In recent years, interests in the application of Wireless Body Area Network (WBAN) have grown considerably. A WBAN can be used to develop a Patient Monitoring system which offers flexibility and mobility to Patients. Use of a WBAN will also allow the flexibility of setting up a remote Monitoring system via either the internet or an intranet. For such medical systems it is very important that a WBAN can collect and transmit data reliably, and in a timely manner to the Monitoring entity. In this paper we examine the performance of an IEEE802.15.4/Zigbee MAC based WBAN operating in different Patient Monitoring environment. We study the performance of a remote Patient Monitoring system using an OPNET based simulation model.
