CACTUS Project Objectives

• Model, design, optimize, and evaluate
  intelligence and context-awareness of an i-DEA
  device
• The interaction between an intelligent device and
  its user
• to carry out specific tasks as a trusted
  assistant
• Taking communication context into account
• USEr-Terminal interaction work package
• The trade-offs and optimizations in computing and
  communications
• information processing and communications amongst
  neighboring devices in an ad-hoc fashion,
• taking usage context into account
• TERMInal-NETwork interaction work package

CACTUS UseT Illustrated (2)

• Research questions addressed
• Electronic assistant that is trusted by user
• Electronic assistant that is consistent across
  platforms and environments
• Electronic assistant that adapts itself to users
  context
• User context task, situation, activity, mood,
  experience, history
• System context resources of network and device,
  applications needs, connectivity,
• Electronic assistant has a model of its user and
  preferences
• Electronic assistant learns from the users
  actions

CACTUS TermiNet Illustrated (2)

• Research questions addressed
• System dynamically adapts routing in ad-hoc
  network depending on changing topology
• System optimizes QoS and democratic resource
  usage in ad-hoc networks
• Application level knows about underlying ad-hoc
  behavior and optimizes high-end application
  (media streaming)
• System uses a context grid to represent
  communications and computing conditions history
