1. A method for location based control of nodes at multiple locations, the method being performed by a control device, the method comprising:
identifying a first location by the control device, wherein the control device includes a control device key database having a first encryption key for communicating at the first location; mapping by the control device a control function that is stored on the control device, wherein the mapping occurs based on the first location such that the control function, while the control device is in the first location, results in a first action being performed in relation to a first node, wherein the first node includes a node key database having a list of approved keys for communication with the first node, and wherein the node key database includes keys for more than one control device; communicating with the first node at the first location, wherein communicating with the first node comprises sending the first encryption key from the control device key database to the first node to authenticate the control device with the location; identifying a second location by the control device; mapping by the control device a control function based on the second location such that the control function, while the control device is in the second location, results in a second action being performed in relation to a second node, wherein the same control function performs a different action in the first location and the second location such that the first action is different from the second action; and communicating with the second node at the second location, wherein communicating with the second node comprises using a second encryption key to communicate with the second node at the second location.
