Extending the reach of online social networks to opportunistic networks with PodNet

Cryptographic Approach of Generic Caching strategy for Opportunistic Wireless Networks (OPPNETS)

“…The Opportunistic wireless networks do not aim to establish an end-to-end path but they make use of the availability of individual devices [6], [7]. There is no assumption about a complete path from one node to another node.…”

Stumbl: Using Facebook to collect rich datasets for opportunistic networking research

“…The rapid proliferation of small wireless devices creates ample opportunity for novel applications [1], as well as for extending the realm of existing ones [2], [3]. Opportunistic or Delay Tolerant Networking (DTN) is a novel networking paradigm that is envisioned to complement and extend existing wireless infrastructure such as 3G and WiFi.…”

“…To date, there are only few small deployments of opportunistic networks [10], [11], [2], [3] from which practical insights of the correlation of social, mobility and communication ties could be gained. Hence, research in this direction is largely based on insights from empirical analysis of datasets typically capturing only one or two of the aspects of relations, but not all three combined.…”

“…However, we assume that opportunistic applications are of social nature and we speculate that they would create similar communication patterns like today's online social network and Web 2.0 platforms, such as Facebook or Twitter. In fact, current online social networks could be run over opportunistic networks [2], [3]. Facebook is a typical, and to date the most widely used, representative of an online social networking service, fostering communication and distribution of (user generated) content among friends.…”

Towards next-generation routing protocols for pocket switched networks

“…PSNs are also applicable in connectivity in areas with limited coverage as well as providing free-of-charge connectivity in situations where roaming charges are expensive. Bernhard et al [115] propose PodNet, an opportunistic architecture concerned with the dissemination of multimedia content or podcasts in the opportunistic realm to (e.g., pictures or video/voice recordings) and from (e.g., YouTube, BBC) the Internet. PodNet extends connectivity by enabling users to deliver content to and from the Internet through a gateway device in an opportunistic manner.…”
