The Internet of Things (IoT) corresponds to a vision of a world in which billions of objects with embedded intelligence, communication means, and sensing and actuating capabilities will connect over IP (Internet Protocol) networks. IoIT proposes to make this vision happen and lay foundations for the future Internet of Interactive Things. We refer to Smart Objects, Cyber-Physical Systems, or just Things as new kinds of entities that include objects of everyday life augmented with micro-controllers, optical and/or radio transceivers, sensors, actuators, and adequate protocol stacks so that they can gather pertinent data from the environment, act upon the environment, and provide an interface to the physical world. When augmented with a novel user interface, they become Interactive Things with five main properties: they can communicate, sense some physical quantities, perform some actions on the physical world, execute reasoning or decision making algorithms, and interact with the user. They are usually highly constrained with limited memory and available energy. Their potentially large number and communication as well as interaction capabilities open new possibilities to create the Internet of Interactive Things that provides unparalleled means for connecting the physical world with the digital universe.


IoIT proposes to address several challenges:

  • Energy-efficient IP connectivity for Interactive Things to enable Things to communicate with each other and with hosts on the Internet.
  • Design of distributed routing and resource allocation algorithms for the Internet of Things.
  • Lightweight security and privacy protocols: supporting openess while enforcing security and privacy of data and communications suitable for highly constrained nodes.
  • Scalable and energy-efficient communications in the 5G cellular networks to integrate low power Things with cellular networks.
  • Novel means for user interaction with Things to provide direct interaction facilities.
