Abstract

In various embodiments, a system within a wireless network comprises a set of battery-powered device (BPD) nodes within the wireless network, and a joining BPD node that identifies, in a subset of BPD nodes, a set of potential parent nodes, filters the set of BPD nodes based on network optimization criteria to identify a target parent node, and transmits a request message to establish a communications link with the target parent node as a child node, where the target parent node in the set of BPD nodes executes instructions to receive the request message from the joining BPD node, evaluate data associated with the joining BPD node with acceptance criteria, and upon determining that the joining BPD node meets the acceptance criteria, establish the communications link with the joining BPD node, where, upon the communications link being established, the joining BPD node is a child to the target parent node.

Dependent claims

A system within a wireless network comprising:

a set of battery-powered device (BPD) nodes within the wireless network, each BPD node in the set of BPD nodes including a memory storing instructions, and a processor coupled to memory that executes the instructions;
and
a joining BPD node within the wireless network, the joining BPD node including a second memory storing a network management application, and a second processor coupled to the memory that executes the network management application to:
identify, in a subset of BPD nodes within the wireless network, the set of BPD nodes as a set of potential parent nodes;
filter, based on a set of network optimization criteria, the set of BPD nodes to identify a target parent node in the set of BPD nodes, and
transmitting a request message to establish a communications link with the target parent node as a child node,
wherein the target parent node in the set of BPD nodes executes the instructions to:
receive the request message from the joining BPD node,
evaluate data associated with the joining BPD node with a set of acceptance criteria, and
upon determining that the joining BPD node meets the set of acceptance criteria, establish the communications link with the joining BPD node, wherein, upon the communications link being established, the joining BPD node is a child node to the target parent node.
