Cars on a street grid

Buildings block the radio at every corner, so a route lives only until the next turn. Delivery (PDR) when 100 cars drive the street grid, 900 s, mean of 20 seeds:

oracle (bound)81.70 %

AODV42.26 %

AntHocNet42.10 %

OLSR9.19 %

Tie on delivery, half the tail

AntHocNet and AODV deliver the same share; AntHocNet's 99th-percentile delay is half of AODV's. The oracle shows how much a perfect router would still deliver: that gap is what v2.2.0 (#537) and v2.3.0's link-lifetime prediction target.

arm	PDR %	delay99 ms
AntHocNet	42.10 ± 0.66	1848 ± 43
AODV	42.26 ± 0.60	3749 ± 48
oracle (100 ms)	81.70 ± 0.45	609 ± 71

When a link breaks

The car at node 8 just turned the corner; its link to 15 is gone. The node that lost its next hop broadcasts a repair ant for that destination, limited to a few hops, instead of telling the source to start over.

Watch for it: an amber ring around node 8, then a new bold trail through 11. The route card on the left logs the switch.

If the repair ant finds nothing in time, the source falls back to reactive forward ants: the slower, wider search you saw when the call started.
