Merza Klaghstan: Privacy and Efficiency Issues in Video Transmission using OppNets


Opportunistic networks are generally characterized by a low performance due to user mobility and non end-to-end communications. This presentation discusses transmitting videos in opportunistic networks, with the objective of enhancing user video viewing experience. We consider this concept as a trade-off between playout delay and the delivered quality level. To obtain the best trade-off, we propose using Scalable Video Coding, SVC, which divides a video into multiple unequally important layers, providing different levels of quality. A further objective is privacy-preserving transmission, so that to ensure keeping transmitted content hidden from unwanted parties.
