Statistical Guarantee Optimization for AoI in Single-Hop and Two-Hop Systems with Periodic Arrivals
Jaya Prakash Champati, Hussein Al-Zubaidy, James Gross
Age of Information (AoI) has proven to be a useful metric in networked systems where timely information updates are of importance. In the literature, minimizing "average age" has r…
On the Distribution of AoI for the GI/GI/1/1 and GI/GI/1/2* Systems: Exact Expressions and Bounds
Jaya Prakash Champati, Hussein Al-Zubaidy, James Gross
Since Age of Information (AoI) has been proposed as a metric that quantifies the freshness of information updates in a communication system, there has been a constant effort in und…
On the Reliability of LTE Random Access: Performance Bounds for Machine-to-Machine Burst Resolution Time
Mikhail Vilgelm, Sebastian Schiessl, Hussein Al-Zubaidy +2
Random Access Channel (RACH) has been identified as one of the major bottlenecks for accommodating massive number of machine-to-machine (M2M) users in LTE networks, especially for…
Delay Performance of Wireless Communications with Imperfect CSI and Finite Length Coding
Sebastian Schiessl, Hussein Al-Zubaidy, Mikael Skoglund +1
With the rise of critical machine-to-machine applications, next generation wireless communication systems must be designed with strict constraints on the latency and reliability. A…
Effective Capacity of Retransmission Schemes - A Recurrence Relation Approach
Peter Larsson, James Gross, Hussein Al-Zubaidy +2
We consider the effective capacity performance measure of persistent- and truncated-retransmission schemes that can involve any combination of multiple transmissions per packet, mu…
Optimal Multi-Server Allocation to Parallel Queues With Independent Random Queue-Server Connectivity
Hussein Al-Zubaidy, Ioannis Lambadaris, Yannis Viniotis
We investigate an optimal scheduling problem in a discrete-time system of L parallel queues that are served by K identical, randomly connected servers. Each queue may be connected…
