3. 3 What is Pervasive Computing or Ubiquitous Computing? Pervasive Computing is the study of a computing technology that pervades the users’ environment by making use of seamless connectivity of multiple independent information devices embedded in the environment of the users. This is done by: Making use of multiple independent information devices (fixed or mobile, homogeneous or heterogeneous) Interconnecting these devices seamlessly through wireless or wired computer communication networks Providing a class of computing / sensory / communication services to a class of users, preferably transparently and can provide personalized services while ensuring a fair degree of privacy / non-intrusiveness. Pervasive Computing is also called Ubiquitous Computing or Invisible Computing. 3 (c) Dr. Rahul Banerjee, BITS-Pilani, IndiaSunday, September 20, 2015

4. Design Principles of Pervasive Computing Systems The pervasive computing system design should try to attain the goals of: – simplicity, – versatility and – Pleasurability while retaining cost-effectiveness, usage-safety and transparency. (c) Dr. Rahul Banerjee, BITS-Pilani, INDIASunday, September 20, 2015 4

5. Self-Configuration & its Importance In order too achieve the pervasive computing system design goals the appliances and the networks comprising of these appliance nodes must be able to: automatically discover other » Devices, » Services and » Parameters In addition, they should be able to carry out unattended negotiation amongst themselves if needed.
