Future Internet

Location aware mobile user and services

Competence

VTT is developing advanced technology for networks of the future. Our expertise covers routing and forwarding, network architectures, protocols and networking solutions that support end-to-end service delivery. An example of service-related solutions is scalable service coding, enabling service flows to adapt to varying transport path conditions. Positioning is another example enabling positioning as part of the service delivery. A third example related to services is a multidisciplinary approach to network and service architectures and mechanisms such as bio-inspired services and networks. We are also experienced in using modern modelling and simulations tools (e.g. MatLab, ns2, OPNET and OMNET++) as part of our development work.

Challenges

Coverage of the Internet is expected to expand up to commodity articles at home and to numerous sensors around our everyday surroundings. This implies the need for longer network addresses, which in turn will lead to the drastic growth of routing table entries in routers and decreased speed of routing. Due to inefficiencies and defects in the original Internet addressing and routing architecture, routing table sizes and the amount of routing messages are already growing superlinearly. The diversity of (wireless) access networks and increasing nomadic usage of networks and services entail the need to support multihoming and mobility. New dissemination and broadcast types of service bring along the demand for efficient multicasting. The vision “always best connected” presupposes that location of the user/terminal is explicitly known and service bit flows can be adapted to transport channel conditions.

Solutions

  • scalable routing and forwarding solutions supporting multicasting, multihoming and mobility
  • scalable layer 2 routing and forwarding concept to speed up routing in core networks
  • scalable service coding schemes
  • cross-layer solutions to support routing, service coding and media adaptation
  • positioning techniques for indoor and outdoor applications, e.g., fingerprinting (WLAN, UMTS, GSM) and sensor-based methods
  • information dissemination and routing in delay-tolerant networks and information dissemination algorithms
  • new Internet and protocol architecture solutions for enhancing the dynamicity in protocol and network management
  • self-healing, self-configuring and self-managed network systems
  • cognitive networks beyond software defined radio and cognitive radio technologies (mobile routers, self-learning network components)
  • real-time control and management signalling architectures and mechanisms for converging wireless and wired networks
  • service mobility solution for information dissemination networks and bio-inspired services and networks.

Benefits

  • technology to support the “always best connected” vision, especially in the “disconnected” network environment, i.e. in an environment where connectivity can not be guaranteed all the time.
  • routing solutions applicable also to very large networks
  • cross-layer capabilities exploited in routing and service coding
  • evolutionary development from legacy (IPv4) networks to future internets
