Probabilistic Caching in Wireless D2D Networks: Cache Hit Optimal vs. Throughput Optimal
Zheng Chen, Nikolaos Pappas, Marios Kountouris
Departing from the conventional cache hit optimization in cache-enabled wireless networks, we consider an alternative optimization approach for the probabilistic caching placement…
Throughput of a Cognitive Radio Network under Congestion Constraints: A Network-Level Study
Nikolaos Pappas, Marios Kountouris
In this paper we analyze a cognitive radio network with one primary and one secondary transmitter, in which the primary transmitter has bursty arrivals while the secondary node is…
Performance Evaluation of Flow Allocation with Successive Interference Cancelation for Random Access WMNs
Nikolaos Pappas, Manolis Ploumidis, Apostolos Traganitis
In this study we explore the performance gain that can be achieved at the network level by employing successive interference cancelation (SIC) instead of treating interference as n…
Optimization of Free Space Optical Wireless Network for Cellular Backhauling
Yuan Li, Nikolaos Pappas, Vangelis Angelakis +2
With densification of nodes in cellular networks, free space optic (FSO) connections are becoming an appealing low cost and high rate alternative to copper and fiber as the backhau…
Network-Level Performance Evaluation of a Two-Relay Cooperative Random Access Wireless System
Georgios Papadimitriou, Nikolaos Pappas, Apostolos Traganitis +1
In wireless networks relay nodes can be used to assist the users' transmissions to reach their destination. Work on relay cooperation, from a physical layer perspective, has up to…
