Best Paper Award at the IEEE GLOBECOM 2015 conference

Iquadrat’s researchers Georgios Kollias and Konstantinos Ramantas received the Best Paper award of the CQRM symposium of the IEEE GLOBECOM 2015 conference, for their work entitled “CORE: A Clustering Optimization algorithm for Resource Efficiency in LTE-A Networks”. The paper considers the creation of Device-to-Device (D2D) based clusters of users where intra-cluster communication will be achieved over UL resources for 5G wireless networks. The minimization of the required resources (equivalent to the maximization of the spectral efficiency), is formulated as an integer (binary) linear optimization problem. A low-complexity clustering optimization algorithm for resource efficiency (CORE), is also devised. Simulation results prove that CORE to increases the spectral efficiency and the network’s capacity.
