Relay-assisted Multiple Access with Full-duplex Multi-Packet Reception
Nikolaos Pappas, Marios Kountouris, Anthony Ephremides +1
The effect of full-duplex cooperative relaying in a random access multiuser network is investigated here. First, we model the self-interference incurred due to full-duplex operatio…
HetNets and Massive MIMO: Modeling, Potential Gains, and Performance Analysis
Marios Kountouris, Nikolaos Pappas
We consider a heterogeneous cellular network (HetNet) where a macrocell tier with a large antenna array base station (BS) is overlaid with a dense tier of small cells (SCs). We inv…
Network-Level Cooperation in Energy Harvesting Wireless Networks
Nikolaos Pappas, Marios Kountouris, Jeongho Jeon +2
We consider a two-hop communication network consisted of a source node, a relay and a destination node in which the source and the relay node have external traffic arrivals. The re…
On the Stability Region of a Relay-Assisted Multiple Access Scheme
Nikolaos Pappas, Marios Kountouris, Anthony Ephremides +1
In this paper we study the impact of a relay node in a two-user network. We assume a random access collision channel model with erasures. In particular we obtain an inner and an ou…
The Stability Region of the Two-User Interference Channel
Nikolaos Pappas, Marios Kountouris, Anthony Ephremides
The stable throughput region of the two-user interference channel is investigated here. First, the stability region for the general case is characterized. Second, we study the case…
