Methods and systems are described for merging of a set of items being shipped using a wireless node network. In an example method, a master node receives ID node identification information from a server in the network. The ID node identification information defines the group of ID nodes. Each of the ID nodes is related to a different item from the set of items being shipped. Next, each of the ID nodes in the group is associated with the master node when the master node detects a signal from each ID node as they respectively approach the master node. When the master node detects a last one of the ID nodes in the group approaching the master node, the master node transmits a notification to the server. Thereafter, the master node receives a shipment merge indication from the server.
