An Evaluation Method of Research on Wearable Wireless Body Area Network in Healthcare  [PDF]
Roberto Vito Rodrigues Filho,Renato Freitas Bulcao Neto,Bruno Oliveira Silvestre,Leandro Luis Galdino de Oliveira
International Journal of Computer Science & Information Technology , 2013,
Abstract: Wearable Wireless Body Area Networks (WWBANs) are an emergent technology enabling the gathering ofreal-time data, for instance, towards decision making by healthcare professionals in the case of remotemonitoring of vital signs of patients. Recent research, however, does not describe in a straightforward wayhow hardware, software and wireless communication platforms fit together in order to fully support aWWBAN-based healthcare application. In this paper we propose a maturity analysis method of research onWWBANs in healthcare. The goal is to analyze whether a paper contemplates features that a researchproject on WWBAN in healthcare should have to apply it in a real world scenario. As a result of ourmethod, features not addressed might indicate the lack of maturity of research papers, or even suggest openissues on that field
Wireless Body Area Network for Medical Healthcare
Jain Prem
IETE Technical Review , 2011,
Abstract: A body area network is a wireless network of biomedical sensors that are attached to a human body. The aim of wireless body area network (WBAN) is to facilitate continuously recording and monitoring of a person′s health condition, if needed, over a long-distance communication network. A sensing system is to be worn by the individual for a long duration. The hardware must be compact and light. This limits the size of the battery. These factors have made energy the most critical resource in WBAN and extending system lifetime has become a priority to fully realize the capabilities of WBAN. This paper presents design and system integration of WBAN technology along with issues and technical challenges of WBAN.

Int'l J. of Communications, Network and System Sciences (IJCNS) , 2009, DOI: 10.4236/ijcns.2009.28093
Abstract: Recent advances in Micro-Electro-Mechanical Systems (MEMS) technology, integrated circuits, and wireless communication have allowed the realization of Wireless Body Area Networks (WBANs). WBANs promise unobtrusive ambulatory health monitoring for a long period of time, and provide real-time updates of the patient’s status to the physician. They are widely used for ubiquitous healthcare, entertainment, and military applications. This paper reviews the key aspects of WBANs for numerous applications. We present a WBAN infrastructure that provides solutions to on-demand, emergency, and normal traffic. We further discuss in-body antenna design and low-power MAC protocol for a WBAN. In addition, we briefly outline some of the WBAN applications with examples. Our discussion realizes a need for new power-efficient solu-tions towards in-body and on-body sensor networks.

Advanced Computing : an International Journal , 2012,
Abstract: Since the population is growing, the need for high quality and efficient healthcare, both at home and in hospital, is becoming more important. This paper presents the innovative wireless sensor network basedMobile Real-time Health care Monitoring (WMRHM) framework which has the capacity of giving health predictions online based on continuously monitored real time vital body signals. Developments in sensors, miniaturization of low-power microelectronics, and wireless networks are becoming a significant opportunity for improving the quality of health care services. Physiological signals like ECG, EEG, SpO2, BP etc. can be monitor through wireless sensor networks and analyzed with the help of data mining techniques. These real-time signals are continuous in nature and abruptly changing hence there is a need to apply an efficient and concept adapting real-time data stream mining techniques for taking intelligent health care decisions online. Because of the high speed and huge volume data set in data streams, the traditional classification technologies are no longer applicable. The most important criteria are to solve the real-time data streams mining problem with ‘concept drift’ efficiently. This paper presents the state-of-the art in this field with growing vitality and introduces the methods for detecting concept drift in data stream, then gives a significant summary of existing approaches to the problem of concept drift. The work is focused on applying these real time stream mining algorithms on vital signals of human body in Wireless Body Area Network( WBAN) based health care environment.
Ubiquitous Healthcare over the World Wide Web
Kuo-Ching Liu,Hui-Feng Huang
Research Journal of Medical Sciences , 2012,
Abstract: Ubiquitous Healthcare is essential not only for providing efficient medical care but also in saving medical expenses. Currently, sensor networks are widely used for applications such as environmental monitoring, airport safety, healthcare, etc. In healthcare situations, sensor nodes can be deployed to remotely monitor and assist disabled patients. Also a concern is the protection of privacy with electronic communication of patient data. However, the sensor networks are easily compromised if an attacker sends forged or modified messages. If a medical unit receives false messages and all efforts of the working staff are implemented under false pretenses, the loss of resources and manpower would be great. Therefore, the receiver (medical unit) has to authenticate messages transmitted from the sensor nodes (monitored patients) over the wireless sensor network. To provide the quality and security of the growing healthcare, it is necessary to reduce the computation load for both parties of the medical unit and the monitored patient. In this study, we will present a new security and privacy of authentication so that ubiquitous healthcare is possible through the sensor network.
The Development & Implementation of Wireless Body Area Networks
Dr Madhumita Dash,Ms Rojalin Mishra
International Journal of Engineering Research , 2014,
Abstract: Abstract : The increasing use of wireless networks and the constant miniaturization of electrical devices has empowered the development of Wireless Body Area Net-works . Wireless Body Area Network is a system of devices in close proximity to a person’s body that cooperate for the benefit of the user where various sensors are attached on clothing or on the body or even implanted under the skin. This paper shows several uses of the BAN technology and the most obvious application of a BAN is in the medical sector, however there are also more recreational uses to BANs. Using a WBAN, the patient experiences a greater physical mobility and is no longer compelled to stay in the hospital. This paper offers a survey of the concept of Wireless Body Area Networks. As WBANs are placed on the human body and often transport private data, security is also considered. This paper will discuss the technologies surrounding BANs, as well as several common applications for BANs.
Towards the fast and robust optimal design of Wireless Body Area Networks  [PDF]
Fabio D'Andreagiovanni,Antonella Nardin
Mathematics , 2015, DOI: 10.1016/j.asoc.2015.04.037
Abstract: Wireless body area networks are wireless sensor networks whose adoption has recently emerged and spread in important healthcare applications, such as the remote monitoring of health conditions of patients. A major issue associated with the deployment of such networks is represented by energy consumption: in general, the batteries of the sensors cannot be easily replaced and recharged, so containing the usage of energy by a rational design of the network and of the routing is crucial. Another issue is represented by traffic uncertainty: body sensors may produce data at a variable rate that is not exactly known in advance, for example because the generation of data is event-driven. Neglecting traffic uncertainty may lead to wrong design and routing decisions, which may compromise the functionality of the network and have very bad effects on the health of the patients. In order to address these issues, in this work we propose the first robust optimization model for jointly optimizing the topology and the routing in body area networks under traffic uncertainty. Since the problem may result challenging even for a state-of-the-art optimization solver, we propose an original optimization algorithm that exploits suitable linear relaxations to guide a randomized fixing of the variables, supported by an exact large variable neighborhood search. Experiments on realistic instances indicate that our algorithm performs better than a state-of-the-art solver, fast producing solutions associated with improved optimality gaps.

International Journal of Distributed Sensor Networks , 2012, DOI: 10.1155/2012/708762
Abstract: In ubiquitous healthcare systems, machine-to-machine (M2M) communication promises large opportunities as it utilizes rapidly developing technologies of large-scale networking of devices for patient monitoring without dependence on human interaction. With the emergence of wireless multimedia sensor networks (WMSNs), M2M communications improve continuous monitoring and transmission and retrieval of multimedia content such as video and audio streams, images, and sensor data from the patient being monitored. This research deploys WMSN for continuous monitoring of target patients and reports tracking for preventive ubiquitous healthcare. This study performs optimization scheme movement coordination technique and data routing within the monitored area. A movement tracking algorithm is proposed for better patient tracking techniques and aids in optimal deployment of wireless sensor networks. Results show that our optimization scheme is capable of providing scalable and reliable patient monitoring results.
