Overage and Staleness Metrics for Status Update Systems
Peng Zou, Jin Zhang, Xianglin Wei +1
Status update systems consist of sensors that take measurements of a physical parameter and transmit them to a remote receiver. Age of Information (AoI) has been studied extensivel…
On Age and Value of Information in Status Update Systems
Peng Zou, Omur Ozel, Suresh Subramaniam
Motivated by the inherent value of packets arising in many cyber-physical applications (e.g., due to precision of the information content or an alarm message), we consider status u…
Maintaining Information Freshness in Power-Efficient Status Update Systems
Parisa Rafiee, Peng Zou, Omur Ozel +1
This paper is motivated by emerging edge computing systems which consist of sensor nodes that acquire and process information and then transmit status updates to an edge receiver f…
Optimizing Information Freshness Through Computation-Transmission Tradeoff and Queue Management in Edge Computing
Peng Zou, Omur Ozel, Suresh Subramaniam
Edge computing applications typically require generated data to be preprocessed at the source and then transmitted to an edge server. In such cases, transmission time and preproces…
Trading Off Computation with Transmission in Status Update Systems
Peng Zou, Omur Ozel, Suresh Subramaniam
This paper is motivated by emerging edge computing applications in which generated data are pre-processed at the source and then transmitted to an edge server. In such a scenario,…
Relative Age of Information: A New Metric for Status Update Systems
Peng Zou, Omur Ozel, Suresh Subramaniam
In this paper, we introduce a new data freshness metric, relative Age of Information (rAoI), and examine it in a single server system with various packet management schemes. The (c…
