Age-of-Information in the Presence of Error | | Kun Chen
; Longbo Huang
; | | Date: |
2 May 2016 | | Abstract: | We consider the peak age-of-information (PAoI) in an M/M/1 queueing system
with packet delivery error, i.e., update packets can get lost during
transmissions to their destination. We focus on two types of policies, one is
to adopt Last-Come-First-Served (LCFS) scheduling, and the other is to utilize
retransmissions, i.e., keep transmitting the most recent packet. Both policies
can effectively avoid the queueing delay of a busy channel and ensure a small
PAoI. Exact PAoI expressions under both policies with different error
probabilities are derived, including First-Come-First-Served (FCFS), LCFS with
preemptive priority, LCFS with non-preemptive priority, Retransmission with
preemptive priority, and Retransmission with non-preemptive priority. Numerical
results obtained from analysis and simulation are presented to validate our
results. | | Source: | arXiv, 1605.0559 | | Services: | Forum | Review | PDF | Favorites | |
