An auto-identification system is described that includes a plurality of distributed auto-id nodes that are operable to track physical objects as they move through an operation of an enterprise, such as, for example, a supply chain network or a sales network. The auto-id nodes are distributed across sites of the network, and are in communication with enterprise application systems and/or data acquisition systems such as RFID readers or sensor devices. By focusing on their respective sites, the auto-id nodes minimize the amount of data tracked by their respective enterprise applications. Further, a simulator may be associated with one or more of the auto-id nodes. In this case, the simulator may project certain movements of the physical objects through an environment of an auto-id node, and then feed corresponding data to the auto-id node. In this way, the auto-id node may be tested and optimized, without requiring actual, physical testing.
