Control of Status Updates for Energy Harvesting Devices that Monitor Processes with Alarms
George Stamatakis, Nikolaos Pappas, Apostolos Traganitis
In this work, we derive optimal transmission policies in an energy harvesting status update system. The system monitors a stochastic process which can be either in a normal or in a…
Optimal Policies for Status Update Generation in a Wireless System with Heterogeneous Traffic
George Stamatakis, Nikolaos Pappas, Apostolos Traganitis
A large body of applications that involve monitoring, decision making, and forecasting require timely status updates for their efficient operation. Age of Information (AoI) is a ne…
Wireless Network-Level Partial Relay Cooperation: A Stable Throughput Analysis
Nikolaos Pappas, Jeongho Jeon, Di Yuan +2
In this work, we study the benefit of partial relay cooperation. We consider a two-node system consisting of one source and one relay node transmitting information to a common dest…
Effect of Energy Harvesting on Stable Throughput in Cooperative Relay Systems
Nikolaos Pappas, Marios Kountouris, Jeongho Jeon +2
In this paper, the impact of energy constraints on a two-hop network with a source, a relay and a destination under random medium access is studied. A collision channel with erasur…
Optimal Utilization of a Cognitive Shared Channel with a Rechargeable Primary Source Node
Nikolaos Pappas, Jeongho Jeon, Anthony Ephremides +1
This paper considers the scenario in which a set of nodes share a common channel. Some nodes have a rechargeable battery and the others are plugged to a reliable power supply and,…
