Optimal Sampling for Data Freshness: Unreliable Transmissions with Random Two-way Delay
Jiayu Pan, Ahmed M. Bedewy, Yin Sun +1
In this paper, we aim to design an optimal sampler for a system in which fresh samples of a signal (source) are sent through an unreliable channel to a remote estimator, and acknow…
Low-Power Status Updates via Sleep-Wake Scheduling
Ahmed M. Bedewy, Yin Sun, Rahul Singh +1
We consider the problem of optimizing the freshness of status updates that are sent from a large number of low-power sources to a common access point. The source nodes utilize carr…
Age-Optimal Low-Power Status Update over Time-Correlated Fading Channel
Guidan Yao, Ahmed M. Bedewy, Ness B. Shroff
In this paper, we consider transmission scheduling in a status update system, where updates are generated periodically and transmitted over a Gilbert-Elliott fading channel. The go…
Battle between Rate and Error in Minimizing Age of Information
Guidan Yao, Ahmed M. Bedewy, Ness B. Shroff
In this paper, we consider a status update system, in which update packets are sent to the destination via a wireless medium that allows for multiple rates, where a higher rate als…
Age-optimal Scheduling over Hybrid Channels
Jiayu Pan, Ahmed M. Bedewy, Yin Sun +1
We consider the problem of minimizing the age of information when a source can transmit status updates over two heterogeneous channels. Our work is motivated by recent developments…
Optimal Sampling and Scheduling for Timely Status Updates in Multi-source Networks
Ahmed M. Bedewy, Yin Sun, Sastry Kompella +1
We consider a joint sampling and scheduling problem for optimizing data freshness in multi-source systems. Data freshness is measured by a non-decreasing penalty function of \emph{…
Optimizing Information Freshness using Low-Power Status Updates via Sleep-Wake Scheduling
Ahmed M. Bedewy, Yin Sun, Rahul Singh +1
In this paper, we consider the problem of optimizing the freshness of status updates that are sent from a large number of low-power source nodes to a common access point. The sourc…
Age-optimal Sampling and Transmission Scheduling in Multi-Source Systems
Ahmed M. Bedewy, Yin Sun, Sastry Kompella +1
In this paper, we consider the problem of minimizing the age of information in a multi-source system, where samples are taken from multiple sources and sent to a destination via a…
The Age of Information in Multihop Networks
Ahmed M. Bedewy, Yin Sun, Ness B. Shroff
Information updates in multihop networks such as Internet of Things (IoT) and intelligent transportation systems have received significant recent attention. In this paper, we minim…
Minimizing the Age of Information through Queues
Ahmed M. Bedewy, Yin Sun, Ness B. Shroff
In this paper, we investigate scheduling policies that minimize the age of information in single-hop queueing systems. We propose a Last-Generated, First-Serve (LGFS) scheduling po…
Age-Optimal Information Updates in Multihop Networks
Ahmed M. Bedewy, Yin Sun, Ness B. Shroff
The problem of reducing the age-of-information has been extensively studied in the single-hop networks. In this paper, we minimize the age-of-information in general multihop networ…
Optimizing Data Freshness, Throughput, and Delay in Multi-Server Information-Update Systems
Ahmed M. Bedewy, Yin Sun, Ness B. Shroff
In this work, we investigate the design of information-update systems, where incoming update packets are forwarded to a remote destination through multiple servers (each server can…
