Many researchers from whole world are at the present working in the ubiquitous computing structure. Their effort impacts all regions of computer science, including hardware components (like chips), interaction substrates, applications, privacy, network protocols and computational techniques (Banavar et al, 2002).
Ubiquitous computing or normally called “ubicomp” is an away desktop or post desktop model of human computer interaction in which data and information processing has been comprehensively incorporated interested in daily life matters and actions. As different to the desktop working and processing, in which a sole user deliberately engages a single device for a meticulous task, someone “employing” ubiquitous computing employs several computational devices and systems at the same time, in the track of normal actions, and possibly will not essentially even be conscious that they are doing so (Stajano, 2002).
Ubiquitous computing is the visualization of a world in which computing power and digital infrastructure are tremendously economical property, so low-priced they are entrenched in all the daily things that enclose us. We can say that ubiquitous computing is not virtual reality, it is not a Personal Digital Assistant or PDA like Apples Newton, and it is not an individual or friendly computer with agents responsible for your bidding. Different from virtual reality, ubiquitous computing actions to put together information exhibit into the daily physical world. It believed that nuances of the authentic world to be magnificent, and plans plainly to augment them. Unlike PDAs, ubiquitous computing visualizes a world of completely associated devices, with inexpensive wireless networks all over the place (Kenneth, 1998). unlike PDAs, it is assumed that you are required nothing with you,
