Age-Aware Stochastic Hybrid Systems: Stability, Solutions, and Applications
Ali Maatouk, Mohamad Assaad, Anthony Ephremides
In this paper, we analyze status update systems modeled through the Stochastic Hybrid Systems (SHSs) tool. Contrary to previous works, we allow the system's transition dynamics to…
Distributed Derivative-free Learning Method for Stochastic Optimization over a Network with Sparse Activity
Wenjie Li, Mohamad Assaad, Shiqi Zheng
This paper addresses a distributed optimization problem in a communication network where nodes are active sporadically. Each active node applies some learning method to control its…
A Novel Algorithm to Report CSI in MIMO-Based Wireless Networks
Muhammad Karam Shehzad, Luca Rose, Mohamad Assaad
In wireless communication, accurate channel state information (CSI) is of pivotal importance. In practice, due to processing and feedback delays, estimated CSI can be outdated, whi…
Dealing with CSI Compression to Reduce Losses and Overhead: An Artificial Intelligence Approach
Muhammad Karam Shehzad, Luca Rose, Mohamad Assaad
Motivated by the issue of inaccurate channel state information (CSI) at the base station (BS), which is commonly due to feedback/processing delays and compression problems, in this…
On the Global Optimality of Whittle's index policy for minimizing the age of information
Saad Kriouile, Mohamad Assaad, Ali Maatouk
This paper examines the average age minimization problem where only a fraction of the network users can transmit simultaneously over unreliable channels. Finding the optimal schedu…
