The increasing number of personal devices with wireless communication capabilities makes it possible the creation of spontaneous networks in which devices communicate occasionally depending on contact opportunities. This intermittent communication may be due to mobility and power-limitations of devices, physical obstacles and distance, resulting in the possible nonexistence of end-to-end paths toward a destination. In summary, spontaneous networks are characterized by being highly dynamic, composed of mobile and static nodes that are able to take advantage of opportunistic time-varying contacts.
This tutorial aims to give an introduction to the challenges and research issues behind the development of
opportunistic networking solutions able to boost the deployment of spontaneous networks. Special attention will be
given to the fundamental building block: routing over opportunistic networks. Since the effciency of spontaneous
networks depends upon the way contacts occur between carriers of communication devices, special attention will
also be given to the analysis of method to detect social structures based on opportunistic contacts. To emphasize
the impact that opportunistic networking technology may have, this tutorial ends up with the description of major
aspects of future forwarding schemes: interest-based and information-centric forwardings.
This presentation was given as a tutorial in the IEEE 3rd Latin-American Conference on Communications (LATINCOM), on Oct 26th, 2011, in Belém/PA, Brazil.
