Sending information through status updates

A Baknina, O Ozel, J Yang, S Ulukus… - 2018 IEEE International …, 2018 - ieeexplore.ieee.org
We consider an energy harvesting transmitter sending status updates regarding a physical
phenomenon it observes to a receiver. Different from the existing literature, we consider a …

Optimizing information freshness through computation–transmission tradeoff and queue management in edge computing

P Zou, O Ozel, S Subramaniam - IEEE/ACM Transactions on …, 2021 - ieeexplore.ieee.org
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 …

Broadcasting with an energy harvesting rechargeable transmitter

J Yang, O Ozel, S Ulukus - IEEE Transactions on Wireless …, 2011 - ieeexplore.ieee.org
In this paper, we investigate the transmission completion time minimization problem in an
