Delay-Optimal Buffer-Aware Scheduling with Adaptive Transmission
Xiang Chen, Wei Chen, Joohyun Lee +1
In this work, we aim to obtain the optimal tradeoff between the average delay and the average power consumption in a communication system. In our system, the arrivals occur at each…
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…
Achieving Delay Rate-function Optimality in OFDM Downlink with Time-correlated Channels
Zhenzhi Qian, Bo Ji, Kannan Srinivasan +1
There have been recent attempts to develop scheduling schemes for downlink transmission in a single cell of a multi-channel (e.g., OFDM-based) cellular network. These works have be…
Update or Wait: How to Keep Your Data Fresh
Yin Sun, Elif Uysal-Biyikoglu, Roy D. Yates +2
In this work, we study how to optimally manage the freshness of information updates sent from a source node to a destination via a channel. A proper metric for data freshness at th…
