INTRODUCTION
The ability to access information and software applications anytime and anywhere is known as Pervasive computing.
The word pervasive means"existing everywhere
The aim of Pervasive Computing is for computing available wherever it's needed.
Ships, Aircrafts, Cars,Shoes, Hats, Tools, Homes and even things like our coffee mugs and even the human body embedded with chips.
Mobile Internet access, Handheld devices, and Bluetooth have made pervasive computing a reality
GOALS
Invisible technology.
Integration of virtual and physical worlds.
Throughout desks, rooms, buildings and life
Devices and services communicating with each other without any human intervention or help.
CHARACTERISTICS OF PERVASIVE COMPUTING
Physical integration: integration between computing nodes and the physical world, e.g., a whiteboard that records what’s on.
Instantaneous Interoperation: devices interoperate spontaneously in changing environments, e.g., a device changes its partners as it moves or as the context changes.
SERVICE DISCOVERY PROTOCOL
Allows devices to advertise, discover, configure and communicate with each other in a network.
Example – When a device is moving between networks it needs to know what all services available and how to contact theses services,
Service Discovery protocols are used for this purpose.
SAP
BENEFITS
Always running and available
Adapt to environments when the users/devices move-reconfigure to use available services.
Users are not aware of the computing embedded in the device-transparent interaction.
Information pursues the user rather than user pursues information
ONGOING RESEARCH PROJECTS
IBM ’s “smarter planet”
The project is about building a smarter planet by including everyday case scenarios like parking the car in a place by communicating with another car.
CONCLUSION
Pervasive Computing is the next era of computer science.
Pervasive computing in an increasingly networked world continues to affect more and more of the world's population.
