Abstract

This disclosure involves neighboring node discovery in a network. For instance, a neighboring node discovery method includes receiving, at a first node, a neighbor solicitation message. The neighbor solicitation message includes an indication that a second node is a low power device and a first scheduled response time. The method also includes transmitting at the scheduled response time, by the first node, a first neighbor advertisement message. The first neighbor advertisement message includes an indication of no availability in a neighbor cache of the first node and a second scheduled respond time. Further, the method includes removing one or more nodes from the neighbor cache, and receiving, at the first node at the second scheduled response time, a second neighbor solicitation message from the second node indicating availability in the neighbor cache. Additionally, the method includes linking the first node and the second node.
