Realizing delay tolerant networking as access enabler : services arizing in new realms and the driving applications

There are many locations that are not within reach, or at least not within affordable reach, of the optical fibres, copper cables, radio waves or even satellite links that make up the physical infrastructure of the world's networks. This makes a true challenge for the Future Internet. One of the new technologies currently being investigated as one possible enabler is Delay Tolerant Networking (DTN), the future standardization of which is prepared in the DTN research group, DTNRG, within the realms of IETF/IRTF. Providing applications that exploit these advances is generally perceived as vital to getting these advances out into the field. It is a reasonable assumption that the applications that are the presently most used in the "normal" internet will continue to be of most importance also in hitherto not ICT covered areas. But, for local SMEs the rational may rather be development of specialized services that increase the efficiency and market potentials for their activities in remote locations.Godkänd; 2009; 20091214 (maud
