Abstract: In one embodiment, a method comprises identifying, by an apparatus, a mesh instability source device that adds a substantial instability influence that substantially degrades network communications in a mesh network, including: determining, for each mesh network device in the mesh network, a corresponding node stability contribution that identifies a long-term capability of the corresponding mesh network device to provide reliable communications for other mesh network devices in the mesh network, and determining a corresponding influence of the node stability contribution on child mesh network devices relying on the corresponding mesh network device for connectivity in the mesh network, and identifying the mesh instability source device as having a corresponding worst influence of the node stability contribution in the mesh network; and eliminating the substantial instability influence based on determining a remediation solution, and causing the remediation solution to be implemented for the mesh instability source device.

Abstract: In one embodiment, a method comprises: determining, by a constrained network device in a low power and lossy network (LLN), a self-estimated density value of neighboring LLN devices based on wirelessly receiving an identified number of beacon message transmissions within an identified time interval from neighboring transmitting LLN devices in the LLN; setting, by the constrained network device, a first wireless transmit power value based on the self-estimated density value; and transmitting a beacon message at the first wireless transmit power value, the beacon message specifying the self-estimated density value, a corresponding trust metric for the self-estimated density value, and the first wireless transmit power value used by the constrained network device for transmitting the beacon message.

Abstract: In one embodiment, a method comprises a management device, in a constrained network comprising constrained network devices, identifying for each constrained network device all available rules for execution by the corresponding constrained network device; the management device generating a prioritized rule set for each constrained network device, each prioritized rule set having selected available rules ordered relative to priority of execution by the corresponding constrained network device relative to a corresponding device context and a corresponding network context of the corresponding constrained network device; and the management device executing, for each constrained network device, a corresponding constrained deployment of the corresponding prioritized rule set based on identifying, from the corresponding prioritized rule set, a lifetimed rule set relative to the corresponding device context and network context, and supplying the lifetimed rule set to the corresponding constrained network device.
