Opportunistic Networks

SPoT: Representing the social, spatial, and temporal dimensions of human mobility with a unifying framework

Modeling human mobility is crucial in the analysis and simulation of opportunistic networks, where contacts are exploited as opportunities for peer-to-peer message forwarding. The current approach to human mobility modeling has been based on …

Less is more: Long paths do not help the convergence of social-oblivious forwarding in opportunistic networks

Message delivery in opportunistic networks is substantially affected by the way nodes move. Given that messages are handed over from node to node upon encounter, the intermeeting time, i.e., the time between two consecutive con- tacts between the …

From pareto inter-contact times to residuals

Interactions between mobile users are the building blocks of a variety of emerging communication paradigms, among which opportunistic networking is one of the most promising. In opportunistic networks, the information propagates through pair-wise …

Modelling social-aware forwarding in opportunistic networks

Opportunistic networks are one of the most promising evolutions of the traditional Mobile Ad Hoc Networks paradigm. Communications in an opportunistic network rely on the mobility of the users: each message is handed over from node to node, making …

Context- and social-aware middleware for opportunistic networks

Opportunistic networks are multi-hop ad hoc networks in which nodes opportunistically exploit any pair-wise contact to share and forward content, without requiring any pre-existing Internet infrastructure. Opportunistic networks tolerate partitions, …

Design and performance evaluation of ContentPlace, a social-aware data dissemination system for opportunistic networks

In this paper we present and evaluate ContentPlace, a data dissemination system for opportunistic networks, i.e., mobile networks in which stable simultaneous multi-hop paths between communication endpoints cannot be provided. We consider a scenario …

Autonomic behaviour of opportunistic network routing

In opportunistic networks, end-to-end communication among users does not require a continuous end-to-end path between source and destination. Network protocols are designed to be extremely resilient to events such as long partitions, node …

ContentPlace: Social-aware data dissemination in opportunistic networks

This paper deals with data dissemination in resource-constrained opportunistic networks, i.e., multi-hop ad hoc networks in which simultaneous paths between endpoints are not available, in general, for end-to-end communication. One of the main …

Exploiting users' social relations to forward data in opportunistic networks: The HiBOp solution

Opportunistic networks, in which nodes opportunistically exploit any pair-wise contact to identify next hops towards the destination, are one of the most interesting technologies to support the pervasive networking vision. Opportunistic networks …

Modelling data dissemination in opportunistic networks

In opportunistic networks data dissemination is an important, although not widely explored, topic. Since opportunistic networks topologies are very challenged and unstable, data-centric approaches are an interesting direction to pursue. Data should …
