The outstanding improvement of communication and sensor technologies has not brought us only convenience to our lives but also envisioning our promising future with no barrier. Real-time information gathering, processing and communication in sensor networks have enriched people's lifestyles as they never imagined before. Wireless sensor networks (WSN) have provided people so much convenience with its variable applications such as environmental monitoring, human-centric applications, military applications, support for logistics, and etc. Most of all, researches on wireless body area networks (WBAN) have been revisited frequently for ubiquitous and affordable healthcare as healthcare related products and applications have obtained great attention for the people who are really concerned about their health, fitness as well as well-being lives. First, this dissertation examines true optimal routing with use of a novel load balancing aware routing algorithms for multipath wireless sensor networks. We propose an innovative multipath routing network design scheme utilizing dynamic load-balancing aware feedback control system that can predict future traffic flow with preloaded traffic control. Then, we narrow down to wireless body area networks applying linear network coding design approach in both network and MAC layers. Through a discussion of the analysis, modeling, implementation, and simulation, we derive the solutions for the proposed designs that can significantly improve the reliability and energy-efficiency of the desired healthcare related systems.

Co-operative and Energy Efficient Body Area and Wireless Sensor Networks for Healthcare Applications


Book Description

With the advances in small and low-cost radio transceivers and RF front-ends development, the possibility of applying ubiquitous and non-invasive sensors integrated into user’s daily clothing and living activities seems more feasible. The ability to share data increases the usefulness of personal information devices, providing features not possible with independent isolated devices. Current wireless sensor solutions are limited in that they do not provide the means to overcome obstacles and shadowing of propagating radio waves. Thus for reliable communications an increase in power consumption is required, reducing battery life. This book addresses the limitations outlined above by designing efficient and compact antenna systems. These systems will be cooperative and also aware of the surrounding environment and neighboring units, providing efficient and low power wireless connectivity for personal area network (PAN) and body area network (BAN) applications. Analysis of wearable antenna design and performance Addresses the Influence of body-worn antennas on radio channels and radio device performance from a power and error rate perspective. Cooperative networking principles applied to body area networks, showing the pros and cons of such concepts Real life case scenarios using ECG sample signals for potential application to healthcare monitoring.

Energy Efficient Embedded System Design for Medical Care System Using Wireless Sensor Network


Book Description

Recent surveys on medical service systems show that the cost of patient monitoring has grown significantly. The widespread use of portable digital medical device makes it possible to provide a more comprehensive tracking of patient conditions. However, the development of a full scale, distributed health monitoring system is much delayed due to the lack of efficient wireless communication in a large distributed network. This becomes a challenging research topic which is to find a way to provide accurate and real time patient information to medical experts in a fast, efficient and cost effective fashion. This paper proposes a novel solution on building a system which links patients and doctors together using embedded system technology and wireless sensor network. The content presented in this thesis introduces the design and implement of such a system.
