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…
