description A method is provided which transmits information using a plurality of data transmission nodes situated along a drill string. In this method, a first node obtains a transmission status of a second node. When the transmission status of the second node indicates that the second node meets a selected performance threshold, information is sent from the first node to the second node. When the transmission status of the second node indicates that the second node does not meet its performance threshold, then the first node obtains a transmission status of a third node. When the transmission status of the third node indicates that the third node meets a selected performance threshold, information is transmitted from the first node to the third node for relaying along the drill string.
