Information Freshness in Multi-Hop Wireless Networks
Vishrant Tripathi, Rajat Talak, Eytan Modiano
We consider the problem of minimizing age of information in multihop wireless networks and propose three classes of policies to solve the problem - stationary randomized, age diffe…
Age-Delay Tradeoffs in Queueing Systems
Rajat Talak, Eytan Modiano
We consider an M server system in which each server can service at most one update packet at a time. The system designer controls (1) scheduling - the order in which the packets ge…
Can Determinacy Minimize Age of Information?
Rajat Talak, Sertac Karaman, Eytan Modiano
Age-of-information (AoI) is a newly proposed performance metric of information freshness. It differs from the traditional delay metric, because it is destination centric and measur…
Scheduling Policies for Age Minimization in Wireless Networks with Unknown Channel State
Rajat Talak, Igor Kadota, Sertac Karaman +1
Age of information (AoI) is a recently proposed metric that measures the time elapsed since the generation of the last received information update. We consider the problem of AoI m…
