Abstract: A present invention provides a method for controlling roles of nodes in a network comprised of enormous nodes dynamically and distributed autonomously in such a way that the entire network can operate distributed autonomously. A method for controlling a field value u0 of node in a network comprises: a step of determining an initial value of said field value u0, and a step of updating said field value u0, the step of updating comprising: advertising said field value u0 to adjacent nodes, measuring an environment parameter ? from the environment of the node, receiving field values un of the said adjacent nodes, recording the field values un, calculating a new field value u0 from the field value u0, the field values un of the adjacent nodes and the environment parameter ? in such a way that field values of nodes whose environment parameter ? are within a constant range agree with given distribution, deleting the previous field value u0, and recording said new field value u0.
