Abstract: Techniques for path selection in a network include a first node in a mesh network receiving, from a second node in the mesh network, a first battery life metric for a path through the mesh network, determining a value representing a remaining battery life of the first node, calculating a second battery life metric based on at least one of the first battery life metric for the path or the value representing the remaining battery life for the first node, and transmitting, to a third node in the mesh network, the second battery life metric.

Abstract: A wireless network includes nodes configured to implement an improved parent and path selection process to efficiently and reliably manage energy consumption of a battery powered device node. When a given node selects a path, the node transmits requests to multiple potential parent nodes. Each potential parent node transmits a metric that is indicative of the remaining battery life of the nodes in the path that includes the respective potential parent node. The given node then selects a parent node, and corresponding path, based on the metrics. More specifically, the given node selects a path, where at least one node on the selected path is less likely to prematurely exhaust the remaining battery life of the node, relative to the nodes in the other potential paths. As a result, the given node selects a path that optimizes battery consumption of the various battery powered nodes in the wireless network.
