Improved methods and networks of components are described for dynamically changing an operational mode of node operations in a wireless node network having at least a plurality of master nodes and a server. A method begins with a first master node detecting an environmental change related to the first master node, such as when the first master node loses reception of a location signal due to surrounding structure. In response to the detected environmental change, changing an operational mode for the first master node to a temporary ID node mode where the first master node no longer can self-determine its location. The first master node operating in the temporary ID node mode then notifies the server that the first master nodes is operating in the temporary ID node mode, and associates with a second master node.
