Optimizing Age-of-Information in Adversarial and Stochastic Environments
Abhishek Sinha, Rajarshi Bhattacharjee
We design efficient online scheduling policies to maximize the freshness of information delivered to the users in a cellular network under both adversarial and stochastic channel a…
LeadCache: Regret-Optimal Caching in Networks
Debjit Paria, Abhishek Sinha
We consider an online prediction problem in the context of network caching. Assume that multiple users are connected to several caches via a bipartite network. At any time slot, ea…
Competitive Algorithms for Minimizing the Maximum Age-of-Information
Rajarshi Bhattacharjee, Abhishek Sinha
In this short paper, we consider the problem of designing a near-optimal competitive scheduling policy for mobile users, to maximize the freshness of available information unif…
Fundamental Limits of Online Network-Caching
Rajarshi Bhattacharjee, Subhankar Banerjee, Abhishek Sinha
Optimal caching of files in a content distribution network (CDN) is a problem of fundamental and growing commercial interest. Although many different caching algorithms are in use…
Fundamental Limits of Age-of-Information in Stationary and Non-stationary Environments
Subhankar Banerjee, Rajarshi Bhattacharjee, Abhishek Sinha
We study the multi-user scheduling problem for minimizing the Age of Information (AoI) in cellular wireless networks under stationary and non-stationary regimes. We derive fundamen…
