With the advancement of technology and miniaturization of electronic devices, applications of
wireless sensor networks (WSNs) can be seen in diverse areas in our lives. In fact, these WSNs
have gained a lot of attention from both the research community and industry, making them
easily available on the market. An extensive amount of research, easy availability, and cheap cost
make them useful in various types of futuristic applications as well.

Optical wireless communication is an emerging and dynamic research and development
area that has generated a vast number of interesting solutions to very complicated
communication challenges. For example, high data rate, high capacity and minimum
interference links for short-range communication for inter-building communication,
computer-to-computer communication, or sensor networks. At the opposite extreme is
a long-range link in the order of millions of kilometers in the new mission to Mars
and other solar system planets.

Today wireless is becoming the leader in communication choices among
users. It is not anymore a backup solution for nomadic travellers but really a
newmoodnaturallyusedeverywhereevenwhenthewiredcommunicationsare
possible. Many technologies evolve then continuously, changing the telecom-
munication world. We talk about wireless local area networks (WLANs), wire-
less personal area networks (WPANs), wireless metropolitan area networks
(WMANs), wireless wide area networks (WWANs), mobile ad hoc networks
(MANETs), wireless sensor networks (WSNs) and mesh networks. Since we
can find today a multitude of wireless technologies we decided to group a

In this research, we have designed, developed implemented a wireless sensor
networks based smart home for safe, sound and secured living environment for
any inhabitant especially elderly living alone. We have explored a methodology
for the development of efficient electronic real time data processing system to
recognize the behaviour of an elderly person. The ability to determine the
wellness of an elderly person living alone in their own home using a robust,
flexible and data driven artificially intelligent system has been investigated. A
framework integrating temporal and spatial contextual information for
determining the wellness of an elderly person has been modelled. A novel
behaviour detection process based on the observed sensor data in performing
essential daily activities has been designed and developed.

sensors are points ofcontact betweenthe material world ofatoms, mass, andenergy
and the seemingly immaterial world of information, computation, and cognition.
Linking these two domains more tightly yields all sorts of practical benefits, such as
improvedinputdevicesforcomputers,moreeffectivemedicaldevices(implantedor
worn), more precise agricultural operations, better monitored buildings or bridges,
more secure payment systems, and more reliable sensor–actuator control systems.
There are many settings in which tighter coupling between digital and physical
planes can enhance safety, security, performance, and reliability.

Radio frequency identification (RFID) technology is witnessing a recent explosion of
development in both industry and academia. A number of applications include supply
chain management, electronic payments, RFID passports, environmental monitoring
and control, office access control, intelligent labels, target detection and tracking, port
management, food production control, animal identification, and so on. RFID is also
an indispensable foundation to realize the pervasive computing paradigm—“Internet of
things.” It is strongly believed that many more scenarios will be identified when the
principles of RFID are thoroughly understood, cheap components available, and when
RFID security is guaranteed.

With the continued growth in the world's population, there is a need to ensure availability of
enough food to feed everyone. Advances in science and technology have helped not only to
increase food production, but also to reduce food wastage. However, the latter has the
potential to be improved to a significant extent through appropriate matching of supply and
demand, and with proper handling during storage and transit. Given the amount of food
wastage that occurs after a food item leaves the “farm” on its way to the “fork,” and the
availability of means to reduce such wastage, there really is no excuse for feigned ignorance.

Radio frequency identification (RFID) is gaining in popularity, especially
as we find ourselves in this communications age and headed towards a
ubiquitous computing world. Automatic identification systems become
an important aspect not just in today’s technology but also as part of our
daily life. We need RFID in our cars, transportation systems, access
points, and even simple transactions; we also acknowledge the need for
RFID in our logistics systems, healthcare, and tracking and locating
applications.

Radio frequency identification (RFID) and Wireless sensor networks (WSN) are
the two key wireless technologies that have diversified applications in the present
and the upcoming systems in this area. RFID is a wireless automated recognition
technology which is primarily used to recognize objects or to follow their posi-
tion without providing any sign about the physical form of the substance. On the
other hand, WSN not only offers information about the state of the substance
and environment but also enables multi-hop wireless communications.
