Category 2 WSNs (C2WSNs): point-to-point or multipoint-to-point (starbased) systems generally with single-hop radio connectivity to WNs, utilizing
static routing over the wireless network; typically, there will be only one route
from the WNs to the companion terrestrial or wireline forwarding node (WNs
are pendent nodes). Residential control systems typically belong to this
category.
