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.
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.
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.
