Table 1 Notations and Explanations

From: Take one for the team: on the time efficiency of application-level buffer-aided relaying in edge cloud communication

Notation Explanation
B Bandwidth of the network link between the edge and the cloud.
d Average size of the homogeneous atomic data entities to be buffered.
di Size of the ith atomic data entity in the buffer.
Dbf Overall size of the buffered data.
Lbf(s) Combinatory latency of buffering and uploading s atomic data entities (under the buffering mechanism).
Lbfup(s) Latency of uploading the buffered s atomic data entities (under the buffering mechanism).
Lfifs(i) Latency of uploading the ith atomic data entity under the FIFS mechanism.
n Amount of atomic data entities (prediagnosis reports in our testbed).
s Buffer size, measured by the amount of atomic data entities.
t0 Starting time point of measuring wall-clock latency.
t1,t2 Ending time points of the first and the second minimum-size communication transactions in the FIFS manner.
tw Time point when an atomic data entity starts waiting to be transmitted.
Tbf Effective buffering time span.
Tcc Time span of the minimum-size communication transaction.
λ Buffering speed with respect to the amount of atomic data entities.
