Mobile Online and On-the. Move Social Networking This SCAMPI application extends the reach of online social networking applications to opportunistic and pervasive networks. It gives ability for users to become involved in participatory social interactions using applications such as content distribution, flea markets, microblogs, and round-based games. While opportunistic networks (through ad hoc communications) leverage users' real-life social network and locality, online networks (through WiMax or 3G) leverage users' distant and virtual social networks. Therefore, the SCAMPI architecture integrates wired and mobile opportunistic networks seamlessly to support hybrid on-the-move and on-line social networking applications. This can be applied to the pervasive video service described previously but also to any other online social networking application such as Flickr, EBay, and Facebook. With such architecture, for example, Xxxxx is able to find easily her concert tickets by putting an ad in the hybrid flea- market application, which extends Ebay to opportunistic domains. She finds sold tickets straight away through the local opportunistic network by people she encounters everyday at her university. Once at the concert, Xxxxx wants to post the collaborative video to her Facebook account but since the infrastructure-based wireless networks such as EDGE/3G are overloaded, that is, have reached capacity limits, SCAMPI hybrid services decide to postpone the publication and resort to opportunistic communication. While commuting back from the concert, Xxxxx plays a round-based game with another commuter through ad hoc connectivity and a distant game opponent through 3G network without being aware of their physical locations. When back at home her mobile device has still enough battery to avoid being recharged since she was mostly using local ad hoc communications with a higher throughput.
