Figure 8

Heat maps of different scenarios. Each plot shows the packet delivery ratio depending on the sender position, scenario (open, building, and trees), and antenna location (dashboard, rooftop).

(a) Scenario 1 (open)/dashboard

(b) Scenario 1 (open)/rooftop

(c) Scenario 2 (buildings)/dashboard

(d) Scenario 2 (buildings)/rooftop

(e) Scenario 3 (trees)/dashboard

(f) Scenario 3 (trees)/rooftop
