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…
On the Performance of Network Coding and Forwarding Schemes with Different Degrees of Redundancy for Wireless Mesh Networks
Manolis Ploumidis, Nikolaos Pappas, Vasilios A. Siris +1
This study explores the throughput and delay that can be achieved by various forwarding schemes employing multiple paths and different degrees of redundancy focusing on linear netw…
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…
