Routing Problem for Unmanned Aerial Vehicle Patrolling Missions -- A Progressive Hedging Algorithm
Sudarshan Rajan, Kaarthik Sundar, Natarajan Gautam
The paper presents a two-stage stochastic program to model a routing problem involving an Unmanned Aerial Vehicle (UAV) in the context of patrolling missions. In particular, given…
Age of Information for Single Buffer Systems with Vacation Server
Jin Xu, I-Hong Hou, Natarajan Gautam
In this research, we study the information freshness in M/G/1 queueing system with a single buffer and the server taking multiple vacations. This system has wide applications in co…
On Competitive Analysis for Polling Systems
Jin Xu, Natarajan Gautam
Polling systems have been widely studied, however most of these studies focus on polling systems with renewal processes for arrivals and random variables for service times. There i…
Peak Age of Information in Priority Queueing Systems
Jin Xu, Natarajan Gautam
We consider a priority queueing system where a single processor serves k classes of packets that are generated randomly following Poisson processes. Our objective is to compute the…
Opportunities for Network Coding: To Wait or Not to Wait
Yu-Pin Hsu, Navid Abedini, Natarajan Gautam +2
It has been well established that wireless network coding can significantly improve the efficiency of multi-hop wireless networks. However, in a stochastic environment some of the…
Critically loaded multi-server queues with abandonments, retrials, and time-varying parameters
Young Myoung Ko, Natarajan Gautam
In this paper, we consider modeling time-dependent multi-server queues that include abandonments and retrials. For the performance analysis of those, fluid and diffusion models cal…
