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 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…
Status Updates with Priorities: Lexicographic Optimality
Ali Maatouk, Yin Sun, Anthony Ephremides +1
In this paper, we consider a transmission scheduling problem, in which several streams of status update packets with diverse priority levels are sent through a shared channel to th…
On the Trackability of Stochastic Processes
Baran Tan Bacinoglu, Yin Sun, Elif Uysal
We consider the problem of tracking an unstable stochastic process by using causal knowledge of another stochastic process . We obtain necessary conditions and sufficien…
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{…
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…
