Title: NETWORK ADDRESS ASSIGNMENT AND RECLAMATION FOR HIERARCHICAL BASED RPL NETWORKS
Abstract:
This invention is an improvement of a Hierarchical Do-Dag based RPL (H-DOC) network configuration where the network address of each node corresponds to its location within the hierarchical network. Network addresses are initialized hierarchically (600). Candidate patent nodes signal availability (602). Candidate child nodes select a candidate parent node (603) and respond with a temporary address (604). The selected candidate parent node acknowledges selection and communicates a hierarchical address for the child node in a transmission to the temporary address (605). The child node changes its address to the hierarchical address from the parent node (606).
