Next Department 3 seminar will take place on Wednesday, January 16th at 2pm in room C005.

Dr. Mauro Passacantando (University of Pisa) will give a presentation entitled “Cooperative Infrastructure and Spectrum Sharing in Heterogeneous Mobile Networks”.

Abstract: To accommodate the ever-growing traffic load and bandwidth demand generated by mobile users, mobile network operators (MNOs) need to frequently invest in high spectral efficiency technologies and increase their hold of spectrum resources; MNOs have then to weigh between building individual networks or entering into network and spectrum sharing agreements. We address here the problem of radio access network and spectrum sharing in 4G mobile networks by focusing on a case when multiple MNOs plan to deploy small cell base stations in a geographical area in order to upgrade their existing network infrastructure. We propose two cooperative game models (with and without transferable utility) to address the proposed problem: for given network (user throughput, MNO market, and spectrum shares) and economic (coalition cost and mobile data pricing model) settings, the proposed models output a cost division policy that guarantees coalition (sharing agreement) stability.

CV: Mauro Passacantando received both M.Sc. and Ph.D. in Mathematics from the University of Pisa. He is currently Assistant Professor of Operations Research at the Department of Computer Science of the same university. He achieved the Italian National Habilitation for full professorship in Operations Research. His research activities are mainly focused on variational inequalities, projected dynamical systems, equilibrium problems, and their applications. Most of his recent work focuses on theory and algorithms for Ky Fan inequalities and on game theoretic approaches to service provisioning problems in cloud and multi-cloud systems. He is author of one monograph and more than forty scientific papers published in international journals and volumes.
