Abstract: In one embodiment, a method comprises: identifying, by a network management device, a location-based device group in a wireless data network comprising constrained wireless network devices, including identifying an identified subset of the constrained wireless network devices as member devices based on the member devices having respective physical locations within the location-based device group; identifying, by the network management device, a member device density for the location-based device group; setting by the network management device, for the location-based device group, a set of deployment group network parameters based on the member device density; and sending, by the network management device, the set of deployment group network parameters to the location-based device group for density-based deployment thereof by the member devices.

Abstract: In one embodiment, a method comprises: establishing, by a network management device, a wireless multicast tree topology for a wireless mesh network, the wireless multicast tree topology comprising a root network device and wireless multicast hubs providing respective wireless multicast areas, the establishing including selecting each wireless multicast hub based on a corresponding location and a corresponding wireless neighbor count; and causing, by the network management device, the root network device to unicast transmit to a selected one or more of the wireless multicast hubs a multicast packet encapsulated within a unicast header, the unicast header causing the selected one or more of the wireless multicast hubs to multicast transmit the multicast packet within a corresponding one or more of the wireless multicast areas.
