Heterogeneous cellular networks (HCNs) with embedded small cells are considered, where
multiple mobile users wish to download network content of different popularity. By caching …

Edge caching, which offers application versatility and a range of benefits, has exerted a
significant impact on the adoption and development of fifth-generation networks and …

In heterogeneous networks (HetNets), the load between macrocell base stations (MBSs)
and small-cell base stations (SBSs) is imbalanced due to their different transmission powers …

We consider the general problem of finding the minimum weight b-matching on arbitrary
graphs. We prove that, whenever the linear programming (LP) relaxation of the problem has …

Many assignment problems, and channel allocation in OFDMA networks is a typical
example, can be formulated as bipartite weighted b-matching (BWBM) problems. In this …

Employing centralized resource management schemes is generally infeasible in large-scale
networks. The deployment of heterogeneous Femtocell Access Points (FAPs) over the …

The fifth generation (5G) communication technologies are envisioned to provide higher data
rates, excellent user-coverage, extremely low latency and power consumption. Such cellular …

The concept of a cellular network overlaid with Femtocell Access Points (FAPs) has
emerged as a new wireless architecture that ensures high data rates and reliable coverage …

Modern engineering and social systems are often too complex to be managed by a
centralized agent. Instead, such systems are commonly structured with multiple …

The studies on network congestion and bandwidth provisioning are often formulated into the
Network Utility Maximization (NUM) framework. This framework is characterized by a …
