The Cost of Delay in Status Updates and their Value: Non-linear Ageing
Antzela Kosta, Nikolaos Pappas, Anthony Ephremides +1
We consider a status update communication system consisting of a source-destination link. A stochastic process is observed at the source, where samples are extracted at random time…
Age of Information Performance of Multiaccess Strategies with Packet Management
Antzela Kosta, Nikolaos Pappas, Anthony Ephremides +1
We consider a system consisting of source nodes communicating with a common receiver. Each source node has a buffer of infinite capacity to store incoming bursty traffic in the…
Dynamic Power Control for Packets with Deadlines
Emmanouil Fountoulakis, Nikolaos Pappas, Qi Liao +2
Wireless devices need to adapt their transmission power according to the fluctuating wireless channel in order to meet constraints of delay sensitive applications. In this paper, w…
Age of Information and Throughput in a Shared Access Network with Heterogeneous Traffic
Antzela Kosta, Nikolaos Pappas, Anthony Ephremides +1
We consider a cognitive shared access scheme consisting of a high priority primary node and a low priority network with secondary nodes accessing the spectrum. Assuming bursty…
