Social-aware content dissemination through opportunistic D2D communications

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...

Privacy-Aware and Scalable Content Dissemination in Distributed Social Networks

Centralized social networking websites raise scalability issues — due to the growing number of participants — and policy concerns — such as control, privacy and ownership of users’ data. Distributed Social Networks aim to solve those by enabling architectures where people own their data and share it whenever and to whomever they wish. However, the privacy and scalability challenges are still to...

Content aware multimedia communications

The demands for fast, economic and reliable dissemination of multimedia information are steadily growing within our society. While people and economy increasingly rely on communication technologies, engineers still struggle with their growing complexity. Complexity in multimedia delivery originates from several sources. The most prominent is the unreliability of packet networks like the Interne...

Optimal Context Aware Transmission Strategy for non-Orthogonal D2D Communications

The increasing traffic demand in cellular networks has recently led to the investigation of new strategies to save precious resources like spectrum and energy. A possible solution employs direct deviceto-device (D2D) communications, which is particularly promising when the two terminals involved in the communications are located in close proximity. The D2D communications should coexist with oth...
