2. UBIQUITOUS COMPUTING IN THE NEXT DECADE:
The endeavor by researchers to produce human-to-human interface through technology in the late 1980s resulted in the creation of the ubiquitous computing discipline, whose objective is to embed technology into the background of everyday life. Currently, we are in the post-PC era where smart phones and other devices are changing our environment by making it more informative.The forefather: Mark Weiser,defined a smart environmrnt, Ubiquitous Computing (ubicomp) The formation of the Internet has striking a foremost landmark towards achieving ubicomp’s vision which enables individual devices to converse with any other devices in the planet. The inter-networking reveals the budding of a apparently endless amount of distributed computing resources . Rogers human centric ubicomp introduce the use of human creativity in exploiting the environment capabilities as compare to Resier’s theory. Caceres and Friday On an anniversary of ubicomp ,they discuss the opportunities and challenges of 20 years.Figure 2: Gartner 2011 Hype Cycle of Emerging Technologies ) For the understanding of a complete IoT vision, a well-organized, protected, scalable and market oriented computing is useful. Cloud computing is the most recent example to appear which promises consistent services delivered through next generation data centres that are focuse on virtualised storage technologies. This stage acts as a recipient of data from the ever-present sensors. The ubiquitous sensing and processing works in the surroundings, unseen from the user. Things’ are made possible. As we budge out from www (static pages web) to web2 (social networking web) to web3 (ubiquitous computing web). To take full benefit of the existing Internet technology, there is a need to arrange large-scale, platform-independent, wireless sensor network communications. Cloud computing fulfill high consistency, scalability and self-sufficiency .
3. DEFINITIONS, TRENDS AND ELEMENTS
As, recognized by Atzori et. al. , IOT can be realized in 3 paradigms:Internet-Oriented (middleware), Things Oriented (sensors) and Semantic Oriented (knowledge). This type of description is necessary due to the interdisciplinary character of the subject, the worth of IoT can be unleashed only in an application field where these 3 paradigms meet with each other. The RFID group explains Internet of Things as :
? Network of interconnected objects(WORLDWIDE) exclusively addressable based on standard communication protocols.
? According to the research projects on the (IOT) Cluster of European explain
Things’ are active participants in business, knowledge and social processes where they are enabled to act together and discuss among themselves and with the environment by exchanging data and information sensed about the environment, while reacting separately to the real world events and affecting it by running processes that trigger actions and produce services with/ without direct human involvement
? According to Forrester:A smart environment
Uses information and communications technologies to make the significant infrastructure mechanism and services of a city administration, learning, healthcare, community safety, real estate, transportation and utilities .
? In our definition,
We make the explanation more user centroidal and do not curb it to any standard communication protocol. This will permit for long-lasting applications to be developed and arranged using the available state-of-the-art protocols at any given point in any time. Our definition of Internet of Things for smart environments is –
Interconnection of sensing and actuating devices provides you the ability to share information across platforms through a unified framework, developing a common operating picture for enabling ground-breaking applications. It can be achieved by unflawed large scale sensing, data analytics and information representation using cutting edge ever-present sensing and cloud computing.
Internet of Things has been recognized as one of the up-and-coming technologies in IT as noted in Gartner’s IT Hype Cycle ( Figure 2).
A Hype Cycle 10 is a method to symbolize the emergence, acceptance, mellowness and impact on applications of particular technologies. The fame of different paradigms varies with era. The web search reputation, as considered by the Google search trends during the last 10 years for the Internet of Things, Wireless Sensor Networks(WSN) and Ubiquitous Computing are shown in Figure 3. From the News Reference Volume data ( Figure 3) it has been observed that the Internet of Things has started gaining recognition.
