Shifting paradigm from mobile computing to ubiquitous/pervasive computing

Abstract

Pervasive computing aims to make our lives simpler through the use of tools that allow us to manage information easily. These "tools" are a new class of intelligent, portable devices that allow the user to plug into powerful networks and gain direct, simple, and secure access to both relevant information and services. Pervasive computing devices are not personal computers as we tend to think of them, but very tiny - even invisible. The aim of this research paper has been to throw light on how the future of human beings will be governed in the light of Ubiquitous/Pervasive Computing. The difference between mobile computing and pervasive computing are highlighted. The working in a Ubiquitous Environment through the use of sensors in different environments is also explained with the help of a figure. Two more technologies Zigbee for connecting multiple devices together and Near Field Communication (NFC) that leverages RIFD are also highlighted. The classification of ubiquitous/pervasive systems into infrastructural and personal systems has been defined. The applications of Pervasive/Ubiquitous systems in different areas have been highlighted. The challenges which this concept faces in terms of risk and security associated with them are brought into light. In the end how pervasive computing can change the mobile environment by sensing and analysis of human behavior are summarized in the form of a conclusion.
