Efficient Dissemination Technique for Opportunistic Networks

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...

Collaborative Data Dissemination in Opportunistic Vehicular Networks

Future opportunistic vehicular networks offers viable means for collaborative data dissemination by high-capacity device-to-device communication. This is a highly challenging problem because a) mobile data items are heterogeneous in size and lifetime; b) mobile users have different interests to different data; and c) dissemination participants have limited storages. We study collaborative data ...

Heterogeneous Epidemic Model for Assessing Data Dissemination in Opportunistic Networks

In this paper we investigate a susceptible-infected-susceptible (SIS) epidemic model describing data dissemination in opportunistic networks with heterogeneous setting of transmission parameters. We obtained the estimation of the final epidemic size assuming that amount of data transferred between network nodes possesses a Pareto distribution, implying scale-free properties. In this context, mo...
