In emergency situations such as catastrophes, the cellular infrastructure can be partially or totally damaged. For rescue teams to transmit and receive on-sight reports using live video and high quality images, the provisioning of seamless coverage with high data rates is inevitable. As cellular networks continue to evolve into more heterogeneous structures regarding the size of deployed cells, the...
Future 5G networks are expected to have the capabilities of providing extremely high data rates, seamless coverage, massive number of connected devices, low latency, etc., in order to support the internet of things era. The dynamic performance of 5G networks is a key feature for controlling the dense and rapidly changing communication environment. Technical issues such as limited frequency resources,...
This paper proposes an optimal Joint-Call Admission Control (JCAC)-based approach for initial radio access technology (RAT) selection for Heterogeneous Wireless Networks (HetNets) composed of two co-located wireless networks supporting two different service classes. The framework of Semi-Markov Decision Process (SMDP) is used to formulate the problem as a JCAC optimization problem involving the design...
