Age of Information Optimization with Preemption Strategies for Correlated Systems
Egemen Erbayat, Ali Maatouk, Peng Zou +1
In this paper, we examine a multi-sensor system where each sensor monitors multiple dynamic information processes and transmits updates over a shared communication channel. These u…
Age of Information Optimization and State Error Analysis for Correlated Multi-Process Multi-Sensor Systems
Egemen Erbayat, Ali Maatouk, Peng Zou +1
In this paper, we examine a multi-sensor system where each sensor may monitor more than one time-varying information process and send status updates to a remote monitor over a comm…
How Costly Was That (In)Decision?
Peng Zou, Ali Maatouk, Jin Zhang +1
In this paper, we introduce a new metric, named Penalty upon Decision (PuD), for measuring the impact of communication delays and state changes at the source on a remote decision m…
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…
Waiting before Serving: A Companion to Packet Management in Status Update Systems
Peng Zou, Omur Ozel, Suresh Subramaniam
In this paper, we explore the potential of server waiting before packet transmission in improving the Age of Information (AoI) in status update systems. We consider a non-preemptiv…
