A method of establishing and updating a master node in a computer network by scoring each node in the network as a function of its physical attributes, designating the highest scoring node as the master node, sending a periodic message by the master node with its score and a request for non-master node scores, sending a message by a non-master node to the master node requesting relinquishment of master node status if the non-master node has a higher score, relinquishing master node status to a non-master node with a higher score and returning to the third step, and declaring by a non-master node that it is a master node if it has not received a message from the previously designated master node in a user-definable period of time and returning to the third step.
