WNCG student Nithin Ramesan received the Best Student Paper Award at the 18th International Symposium on Modeling and Optimization in Mobile, Ad Hoc and Wireless Networks (WiOpt 2020). 

This is the second year in a row that the award has gone to a WNCG student.

Ramesan’s winning paper, "Wireless Queues in Poisson Interference Fields: the Continuum Between Zero and Infinite Mobility," was co-authored with his advisor, Prof. François Baccelli.

The paper explores the time evolution of a queue placed in a Poisson point process of moving wireless interferers. The research is largely concerned with how the evolution of the queue changes with different degrees of mobility in the system. The queue evolves according to an external arrival process and a time-varying service process that is a function of the SINR that it experiences.

“We first show that when there is no mobility in the system, the queue is unstable with positive probability,” Ramesan explained. “We then prove that any non-zero mobility in the system allows for queue stability conditions to be established.”

What the researchers found was that increased motion in the system leads to increased reliability of service in queues, and therefore decreased mean length and decreased mean delay.

“The key takeaway is that mobility in wireless networks is beneficial for wireless queues,” Ramesan stated.

Nithin Ramesan is a Ph.D. student advised by François Baccelli. He joined WNCG after receiving the B.Tech. in Electrical, Electronics and Communications Engineering from the Indian Institute of Technology, Madras. His research interests include theoretical problems in the fields of wireless networks, queueing networks and generally applied probability.
