Analysis of the shortest relay queue policy in a cooperative random access network with collisions
Mayank Saxena, Ioannis Dimitriou, Stella Kapodistria
The scope of this work is twofold: On the one hand, strongly motivated by emerging engineering issues in multiple access communication systems, we investigate the performance of a…
On the analysis of partially homogeneous nearest-neighbour random walks in the quarter plane
Ioannis Dimitriou
This work deals with the stationary analysis of two-dimensional partially homogeneous nearest-neighbour random walks. Such type of random walks in the quarter plane are characteriz…
On the power series approximations of a structured batch arrival two-class retrial system with weighted fair orbit queues
Ioannis Dimitriou
We provide power series approximations for a structured batch arrival single server retrial system with two infinite capacity weighted fair orbit queues, i.e., the re-transmission…
On the Benefits of Network-level Cooperation in IoT Networks with Aggregators
Nikolaos Pappas, Ioannis Dimitriou, Zheng Chen
In this work, we consider a random access Internet of Things IoT wireless network assisted by two aggregators collecting information from two disjoint groups of sensors. The nodes…
A two-class queueing system with constant retrial policy and general class dependent service times
Ioannis Dimitriou
A single server retrial queueing system with two-classes of orbiting customers, and general class dependent service times is considered. If an arriving customer finds the server un…
