Multimedia data dissemination in opportunistic systems
… Consequently, we target in this thesis a video dissemination scheme in OppNets. For the video delivery problem in the sparse opportunistic networks, we propose a solution with the objective of reducing the video playout delay, so that enabling the recipient to play the video content as soon as …

Content dissemination for static and dynamic mobile P2P groups
In this thesis we present content dissemination protocols for static and dynamic peer-to-peer (P2P) groups. In the first part of the thesis we delve into the problem of inefficient content dissemination for static mobile device users due to cellular congestion. We propose the Sangam Framework which …

Modeling the Dissemination of Antibiotic Resistance in Aquatic Environments
The emergence of antibiotic resistance in riverine systems has become a growing issue worldwide. The use of watershed-scale models is popular with many other water quality issues but not in the case of antibiotic resistance. In this study, we introduce a watershed-scale bacteria fate and transport …
