Optimal Age over Erasure Channels Elie Najm, Emre Telatar, and Rajai Nasser Abstract Previous works on age of information and erasure channels have dealt with specific models and computed the average age or average peak age for certain settings. In this paper, given a source that produces a letter every T s seconds and an erasure channel Webthe case of multiple sources over an erasure channel. This paper includes extensions of the works in [24], [25] to the case of multiple sources. Other works in the litera-ture focusing on channel erasures without energy harvesting constraints include, e.g., [41]–[43]. Studying multiple sources with energy harvesting has been
WebAug 18, 2024 · Abstract: A status updating system is considered in which data from multiple sources are sampled by an energy harvesting sensor and transmitted to a remote destination through an erasure channel. The goal is to deliver status updates of all sources in a timely manner, such that the cumulative long-term average age-of-information (AoI) is …
WebJul 11, 2024 · The age–energy trade-off in the erasure channel was studied in [ 35 ], and the fading channel case was investigated in [ 36 ]. Ref. [ 37] adopted a truncated automatic repeat request (TARQ) scheme and characterized the age–energy trade-off for the IoT monitoring system. earnings on the internetWebPDF - Given a source that produces a letter every T s seconds and an erasure channel that can be used every T c seconds, we ask what is the coding strategy that minimizes the time-average "age of information" that an observer of the channel output incurs.
