Introduction
Sensor networks permit data gathering and computation to be
deeply embedded in the physical environment.
WSN is built by connecting a group of nodes together to perform
the required tasks. Tese nodes cooperate and automatically create
a network among themselves. Wireless sensor node, also commonly
known as mote.
Today, WSN technologies have the potential to change the way of
living with many applications in industry, travel, trade, environment
monitoring, medicine, care of the dependent people, and emergency
management and many other areas.
Wireless sensors, sensor networks, information technology (IT)
and artifcial intelligence, together have built a new interdisciplinary
branch of biomedical engineering in order to overcome the challenges
we face in everyday life. One of the major challenges of the world is
the continuous elderly population increase in the developed countries.
Population reference bureau [1] forecasts that in the next 20 years, the
65-and-over population in the developed countries will be nearly 20%
of the overall population. It means the need of delivering quality care to
a rapidly growing population of elderly while reducing the healthcare
costs is an important issue as well. One hopeful application in this area is
the integration of sensing and consumer electronics technologies which
would allow people to be constantly monitored. In-home pervasive
networks may assist residents and their caregivers by providing
continuous medical monitoring, memory enhancement, control of
home appliances, medical data access, and emergency communication
[2]. Continuous monitoring will increase early detection of emergency
conditions and diseases for at risk patients and also provide wide range
of healthcare services for people with various degrees of cognitive and
physical disabilities [3]. Not only the elderly and persistently ill but also
the families in which both parents have to work will derive advantage
from these systems for delivering high-quality care services for their
babies and little children. Researchers in computer, networking,
biomedical engineering and medical felds are working together in order
to make the broad vision of smart healthcare possible. Te importance
of integrating large-scale wireless telecommunication technologies
such as 3G, Wi-Fi Mesh, and WiMAX, with telemedicine has already
been addressed by some researchers. Further improvements will be
achieved by the coexistence of small-scale personal area technologies
like radio frequency identifcation (RFID), Bluetooth, ZigBee, and
wireless sensor networks, together with large scale wireless networks to
provide context-aware applications [4].
In addition providing pervasiveness with existing and relatively
more mature wireless network technologies, the development of
small or wearable sensor devices is a mater of today researches. Tese
researches may lead to enabling not only accurate information but also
reliable data delivery.
Furthermore, the integration of all these technologies is the
application, which is the coordinator between the caregivers and the
caretakers and between the sensor devices and all of the actors in the
overall system cycle. Since the application is the core of the high-quality
healthcare service concept, the need for intelligent, context-aware
healthcare applications will be increased.
Given the importance of the subject, there are already several
applications and prototypes on the issue. For example, some of them
are devoted to continuous monitoring for cognitive disorders like
Alzheimer’s, Parkinson’s or similar cognitive diseases. Some focus
on fall detection, posture detection and location tracking and others
make use of biological and environmental sensors to identify patients’
health status. Tere is also signifcant research efort in developing
tiny wireless sensor devices, preferably integrated into fabric or other
substances and be implanted in human body.
Some other studies [5-10] have either only smart home perspective
or limited information about the design issues and challenges. Te
interested reader may fnd a wonderful survey on wireless sensor
networks for health care [11].
In our paper we provide discussions not only from a smart home
perspective but rather from a more healthcare related perspective. We

Abstract
Born on other applications, wireless sensor networks (WSNs) grew on the promise of biomedical engineering
applications. In this research we suggest system architecture for smart healthcare, based on a novel WSN. Our system
particularly targets assisted-living residents and others who may help from continuous remote health monitoring. We
present the objectives, advantages, and status of the design. An experimental livelihood space has been constructed at
the Department of Biomedical Engineering (DBE) at Iran University of Science and Technology (IUST) for assessment
of our system. A ten days monitoring and experimental results suggest a physically powerful potential for WSNs to open
new research area in biomedical engineering, i.e. for low-cost, ad hoc use of multimodal sensors for a better quality of
medical care.
