Real-Time Reconstruction and Actuation Error Analysis for Markov Sources over MPR Channels
Pansee S. Elessawy, Nikolaos Pappas
We study real-time reconstruction and actuation for two binary Markov sources that share a wireless multi-packet reception (MPR) channel. Each sensor follows a stationary randomize…
Remote State Estimation over a Wearing Channel: Information Freshness vs. Channel Aging
Jiping Luo, George Stamatakis, Osvaldo Simeone +1
We study the remote estimation of a linear Gaussian system over a channel that wears out over time and with every use. The sensor can either transmit a fresh measurement in the cur…
Computing the Exact Pareto Front in Average-Cost Multi-Objective Markov Decision Processes
Jiping Luo, Nikolaos Pappas
Many communication and control problems are cast as multi-objective Markov decision processes (MOMDPs). The complete solution to an MOMDP is the Pareto front. Much of the literatur…
Version AoI Optimization under Power and General Distortion Constraints in Uplink NOMA
Gangadhar Karevvanavar, Rajshekhar V. Bhat, Nikolaos Pappas
The Version Age of Information (VAoI) quantifies information freshness by measuring the number of versions the receiver lags behind. This paper studies VAoI minimization in an -…
On the Role of Age and Semantics of Information in Remote Estimation of Markov Sources
Jiping Luo, Nikolaos Pappas
This paper studies semantics-aware remote estimation of Markov sources. We leverage two complementary information attributes: the urgency of lasting impact, which quantifies the si…
Exploiting Data Significance in Remote Estimation of Discrete-State Markov Sources
Jiping Luo, Nikolaos Pappas
We consider semantics-aware remote estimation of a discrete-state Markov source with both normal (low-priority) and alarm (high-priority) states. Erroneously announcing a normal st…
