In Device-to-Device (D2D) enabled cellular networks, user-to-network relaying can be handled for improving the performance of cellular networks. When relays are in mobility, a dynamic relay selection strategy is unavoidable. In this paper, we propose

Optimal D2D Content Delivery for Cellular Network Offloading

Autor: James Roberts, Berna Sayrac, Antonia Maria Masucci, Salah Eddine Elayoubi

Publikováno v: Mobile Networks and Applications. 22:1033-1044

We evaluate the throughput performance of a mobile network cell where device to device (D2D) communication, using part of the resource blocks of the considered cell, is used to offload the base station (BS) of part of its content delivery traffic. We

On Mobility Parameter Configurations That Can Lead to Chained Handovers

Autor: Pascal Bianchi, Ovidiu-Constantin Iacoboaiea, Berna Sayrac, Sana Ben Jemaa

Publikováno v: IEEE Transactions on Communications. 64:5136-5148

Optimization of mobile networks is a crucial task for operators aiming to offer a high quality of service. In this paper, we focus on the handover (HO) problem. An HO is the procedure through which a user changes its serving cell, ensuring service co

SON Coordination in Heterogeneous Networks: A Reinforcement Learning Framework

Autor: Ovidiu-Constantin Iacoboaiea, Sana Ben Jemaa, Pascal Bianchi, Berna Sayrac

Publikováno v: IEEE Transactions on Wireless Communications. 15:5835-5847

An important problem of today’s mobile network operators is to bring down the capital expenditures and operational expenditures. One strategy is to automate the parameter tuning on the small cells through the so-called self-organizing network (SON)
