Waiting but not Aging: Optimizing Information Freshness Under the Pull Model

no code implementations17 Dec 2019 Fengjiao Li, Yu Sang, Zhongdong Liu, Bin Li, Huasen Wu, Bo Ji

Interestingly, we find that under this new Pull model, replication schemes capture a novel tradeoff between different values of the AoI across the servers (due to the random updating processes) and different response times across the servers, which can be exploited to minimize the expected AoI at the user's side.
