Seminar by Dr Lorenzo Valerio from CNR Pisa (Italy)

"Adaptive Data Offloading in Opportunistic Networks through an Actor-Critic Learning Method"

The seminar has been postponed until Monday, Sept 1st.


The growing popularity of mobile phones has resulted in an exponential growth of mobile data, causing severe traffic overload in the cellular network. A promising approach to overcome this problem is to delegate part of the traffic to other networks, such as opportunistic networks. However, in opportunistic networking, achieving efficient and timely content delivery could be very challenging. We propose an adaptive offloading solution based on an actor-critic algorithm, where the controller of the dissemination process, once trained, is able to perform at any time the most appropriate choice about the number of content replicas to be injected in the opportunistic network to guarantee the timely delivery of contents to all interested users. This talk will show how our system is able to automatically learn the best strategy to reduce the traffic on the cellular network, without relying on any additional context information about the opportunistic network.

Short  bio

Lorenzo Valerio received his Ph.D. at the Department of Mathematics, University of Milan. Currently, he is Researcher at the Institute for Informatics and Telematics of the National Research Council in Pisa. His current research interests include the inference of spatial and temporal processes, the connection between mobility, and computational learning models, and  mobile technologies such as data offloading and data dissemination in mobile networks.
