We consider the main costs and gains for the management of a Long Term Evolution (LTE) cellular network exploiting e-NodeB (eNB) Sleep Mode (SM). More in depth, we develop an algorithm, called EURA, that is able to target a sustainability metric. The sustainability of the system takes into account the costs of energy consumed by active eNBs, the costs for repairing an eNB when it fails (as a consequence...
A critical issue of a Cognitive Radio Network is the interference generated by secondary users simultaneously accessing and transmitting over the primary user spectrum band. In this paper, we introduce and study a distributed and opportunistic access scheme for MIMO ad-hoc cognitive radio networks identified as OPTIM-COG (OPporTunistic Interference control for Mimo COGnitive radio). OPTIM-COG is based...
A critical issue in Cognitive Radio Networks is the interference generated by secondary users when they simultaneously access and transmit over a spectrum portion reserved to licensed users. In this paper, we propose a method that allows to decide whether a pair of unlicensed users can communicate over a licensed spectrum without causing harmful interference at the primary receiver. The proposed solution...
