UCR: User-centric Routing (05.2010-04.2013)

COPELABS Coordination: Paulo Mendes


In user provided networks, forwarding and routing challenges differ from the traditional Internet routing scenarios  due to the fact that end user devices may behave as network nodes and nodes are highly nomadic. Also in user provided  networks, data is exchanged based on individual user interests and expectations, control and management requires de-centralized and distributed solutions and routing may take advantage of user mobility patterns.

The characteristics of user-provided networks require two basic properties: robustness from an end-to-end perspective, and intermittent connectivity support as such the UCR (User-Centric Routing) project will consider recent trends in wireless communications that will be used to develop novel routing metrics, algorithms and protocols for scenarios where information routing and relaying may be provided by end-user devices, and where networking nodes are essentially characterized by having restricted resources and a highly nomadic behaviour.
