Contents through Networks



This report presents the main findings of my scientific research after my PhD Thesis and especially in the last 8 years. During this period I have worked on three major topics, which span a wide spectrum of networking aspects: Cloud-RAN architecture for cellular networks, wireless edge-caching, and information diffusion in online social platforms. These relate to breakthroughs in communication networks during the last decade, considering the evolution towards 5G cellular networks and the proliferation of on-line social platforms. My research has resulted in original contributions in all three areas that advance the state of the art. In C-RAN architectures novel base station clustering mechanisms are proposed and the performance benefits from collaborative transmission is quantified for very large networks. In edge-caching new cache management policies are introduced that profit from multi-coverage, while user association and mobility is taken into account. Finally, in social networks an original mathematical model combines user posting activity with graph structure to exactly describe user influence inside online platforms. This research was made possible with the collaboration of several PhD and Master students.
