Sweep: pause¶
Varies: pause time (s) — 0 (constant motion) → 900 s (static).

Provenance — measured at
v1.3.0. Every number on this page was produced by the campaign runs named below, all of which predate thev1.3.0tag (19009be). No commit betweenv1.2.0and that tag changes routing behaviour, so checking outv1.3.0reproduces these cells. The default branch will not: it has since changed the pheromone weighting (#327,betaAnts/betaData2.0 → 20) and the per-seed RNG stream assignment (#352), either of which moves measured values. See Provenance and #365.
What it varies¶
Reproduces Fig. 2 of the AntHocNet paper (Di Caro/Ducatelle/Gambardella, PPSN VIII 2004, §4): the random-waypoint pause time is swept from 0 to 900 s, taking the field from constant motion to effectively static. It is also the shape checked by the Broch pause-sweep validation anchor — AODV PDR must rise with pause, and DSDV must be worst under high mobility (see methodology.md). Unlike the paper (AODV only), every baseline is run on identical realisations.
Defined as SWEEPS["pause"] in
ns3/tools/run-scenarios.py
(scenario=paper areaX=2500, pause ∈ {0, 100, 300, 600, 900}).
How it is produced¶
Sweeps are too heavy for the per-merge benchmarks workflow, which runs
only the discrete scenarios. They come from the manual Scenario matrix +
charts workflow (scenario-matrix.yml), which renders sweep-pause.png into
docs/benchmarks/ and uploads the classified CSV; the table below is
filled in by pointing update-benchmarks.py at that CSV.
Raw sweep data rescued from expired artifacts lives in
../campaign/. The published table below comes from the
2026-08-03 20-seed re-run (runs 30850273352 / 30850282055 /
30850291550 / 30850299279 / 30850306777, one point per job, 3.42-opt
image, 900 s, range/disk PHY), rescued as ../campaign/308502*-run.csv and
summarizable with the benchmark-results skill's sweep_summary.py. The
superseded pre-#88/#169 5-seed data remains at
30031904151-pause-disk.csv.
Results¶
Post-#88/#169, 20 seeds, 95% CIs. These numbers include the
T_hop= 3 ms fix (#88, PR167) and the reactive-hop-cap removal¶
(#169, PR #170), and meet the methodology runs floor. Versus the superseded 5-seed data, AntHocNet's PDR moved +9.8 to +26.9 pp across the sweep (baselines moved ≤ ~1.5 pp, consistent with the 5→20 run-count change) — the re-run existed precisely because #88/#169 invalidated the old numbers. The delay99 column carries the known #21 tail (remediation tracked in #308). Do not quote
path_div_*/entropyfrom these cells (#230 window caveat).
