From: Federated semantic nodes to scale search process in the IoT
Building global location knowledge. This figure presents a double cascading process allowing nodes of a federation to share the description of their “location”. First, all descriptions reach the top-node of the federation that merges and computes them in order to have an overall view on how nodes are localized. Second, it spreads the processed information back to all nodes, enabling knowledge to be shared.
