Secure and Usable Services in Opportunistic Networks
… popularity of cloud computing and online social networks. These enable the building of new services based on social information and the reducing cost of building new services. Despite the benefits cloud computing and online social networks bring, the necessity of the cloud availability, ownership …

Leveraging clustering for efficient communication in opportunistic networks
… for efficient communication in delay tolerant networks (DTNs), with a particular focus on pocket switched networks (PSNs), an emerging class of ad hoc networks made up of smartphones and other portable mobile devices carried by humans. Communication in such an infrastructure-less scenario is …

The Impact of Rogue Nodes on the Dependability of Opportunistic Networks
Opportunistic Networks (OppNets) are an extension to the classical Mobile Ad hoc Networks (MANETs) where the network is not dependent on any infrastructure (e.g. Access Points or centralized administrative nodes). OppNets can be more flexible than MANETs because an end to end path does not exist …

Privacy Preserving Enforcement of Sensitive Policies in Outsourced and Distributed Environments
… distributed environments are cloud computing and opportunistic networks, respectively. In this dissertation, we present the design, technical and implementation details of our proposed policy-based access control mechanisms for untrusted environments. First of all, we provide full confidentiality …

Multimedia data dissemination in opportunistic systems
Opportunistic networks (OppNets) are human-centric mobile ad-hoc networks, in which neither the topology nor the participating nodes are known in advance. Routing is dynamically planned following the store-carry-and-forward paradigm, which takes advantage of people mobility. This widens the range …
