Scenario: dense-small¶
Class: dense / low-mobility
← Benchmark index · Metrics · Methodology
Provenance — regenerated on every merge. Unlike the sweep pages, this table is not pinned to a release:
benchmarks.ymlre-runs the discrete taxonomy on every merge to the default branch and rewrites the generated block below, so these numbers track the current tip ofmainand already include the pheromone-weighting change (#327) and the per-seed RNG stream assignment (#352). They are a per-merge regression signal at the 10-run publication floor (#318); the release-pinned, 20-seed numbers live on the sweep and headline pages. See Provenance and #365.
What it stresses¶
The fast CI regime; AntHocNet's hard case. A small, dense, barely-mobile field
that runs cheaply enough for the per-merge benchmarks workflow, so it is the
scenario that gives the quick regression signal.
Configuration¶
| nodes | area long edge (m) | max speed (m/s) | pause (s) | flows | propagation |

Defined as DISCRETE["dense-small"] in
ns3/tools/run-scenarios.py
(nNodes=16 area=250 speed=5 pause=1 flows=4 range=0). The per-merge
benchmarks workflow runs the taxonomy with --quick.
Results¶
Caveat —
large-scaleandheavy-loadcurrently reflect an open defect. #173 (P1, open): withenableMultipathon, reactive forward ants are bounded neither by a broadcast budget nor by(src,seq)duplicate suppression, so route discovery floods combinatorially in dense graphs. Read those two rows as a bug report, not as protocol character. See docs/fidelity.md.
