Group-Purchase Scheme for Content Dissemination in Opportunistic Networks

Analysis of cognitive heuristics for content dissemination in opportunistic networks

When faced with large amounts of data, human brains are able to swiftly react to stimuli and assert relevance of discovered information, even under uncertainty and partial knowledge. These efficient decision-making abilities rely on socalled cognitive heuristics, which are rapid, adaptive, lightweight yet very effective schemes used by the brain to solve complex problems. In a content-centric f...

PodNetSec: Secure Opportunistic Content Dissemination

PodNet: PodNet [1] (Fig. 1(a)) targets mobile content distribution by extending the traditional podcasting concept to opportunistic peer-to-peer content delivery among users via IEEE 802.11 wireless communications in ad hoc mode. Content is organized as episodes in channels, which users can subscribe to and download content once a peer within range holds new episodes. Information thus spreads f...

Data Dissemination in Opportunistic Networks

Mobile devices integrating wireless short-range communication technologies make possible new applications for spontaneous communication, interaction and collaboration. An interesting approach is to use collaboration to facilitate communication when mobile devices are not able to establish direct communication paths. Opportunistic networks, formed when mobile devices communicate with each other ...

Data Dissemination in Opportunistic Networks

Opportunistic networks represent one of the most interesting evolution of traditional Mobile Ad Hoc NETworks (MANET). The typical MANET scenario comprises mobile users with their wireless-enabled mobile devices that cooperate in an ad hoc fashion to support communication without relying on any pre-existing networking infrastructure. Specifically, in MANETs the nodes of the network become active...
