History

• The most profound technologies are those that
  disappear. They weave themselves into the fabric
  of everyday life until they are indistinguishable
  from it.
• - Mark Weiser (1952-1999) (Xerox PARC)
• The founder of Ubiquitous computing

Weisers principles

• The purpose of a computer is to help you do
  something else
• The best computer is a quiet, invisible servant
• The more you can do by intuition the smarter you
  are- the computer should extend your unconscious
• Technology should create calm.

Pervasive Computing

• Pervasive Existing everywhere
• It is also referred as Ubiquitous computing,
  ambient intelligence, everyware.
• Environments saturated with computing and
  communication capability, yet gracefully
  integrated with human users - M. Satyanarayanan
• People and environments augment with
  computational resources that provide information
  and services when and where desired - Mark Weiser

Principles of Pervasive Computing

• Decentralization
• Diversification
• Connectivity
• Simplicity
• One of the central concepts of pervasive
  computing is the automatic organization of
  technical systems to enable capabilities that are
  important to people in a given environment

Components

• Proximity wireless (Bluetooth, WLAN, low-power
  radios, optical, non-RF)
• Near field access( RFID,NFC)
• Sensors and related networking( biometrics,
  wearable sensors, environmental sensors)
• Pervasive networking(Peer-2-peer, ad-hoc,
  communication middleware, self-healing)
• Proximity-cellular interactions (
  vertical-roaming, multiple interfaces terminals)
• Distributed application middleware (UPnP, Jini,
  Web services, Service discovery (SDP))
• Pervasive security( distributing trust, virus
  protection, platform security, visitor scenarios)
• Distributed applications( tools, languages,
  scripts)
• Location and context awareness (presence,
  location awareness technology, middleware)
