Lagrange Index based Scheduling for Minimizing Age of Updates from Heterogeneous Sources
Aniket Mukherjee, Joy Kuri, Chandramani Singh
Modern sensing systems generate heterogeneous updates ranging from small status packets to large data objects. We study a single-hop wireless uplink network where sensors generate…
Age Aware Content Fetching and Broadcast in a Sensing-as-a-Service System
Ankita Koley, Anu Krishna, Chandramani Singh +1
We consider a Sensing-as-a-Service (S2aaS) system consisting of a sensor, a set of users, and a sensor cloud service provider (SCSP). The sensor updates its content each time it ca…
Dynamic Content Caching with Waiting Costs via Restless Multi-Armed Bandits
Ankita Koley, Chandramani Singh
We consider a system with a local cache connected to a backend server and an end user population. A set of contents are stored at the the server where they continuously get updated…
Fresh Caching of Dynamic Contents using Restless Multi-armed Bandits
Ankita Koley, Chandramani Singh
We consider a dynamic content caching problem wherein the contents get updated at a central server, and local copies of a subset of contents are cached at a local cache associated…
Caching Contents with Varying Popularity using Restless Bandits
Pavamana K J, Chandramani Singh
We study content caching in a wireless network in which the users are connected through a base station that is equipped with a finite-capacity cache. We assume a fixed set of conte…
Caching Contents with Varying Popularity using Restless Bandits
Pavamana K J, Chandramani Kishore Singh
Mobile networks are experiencing prodigious increase in data volume and user density , which exerts a great burden on mobile core networks and backhaul links. An efficient techniqu…
