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 uof node in a network comprises: a step of determining an initial value of said field value u, and a step of updating said field value u, the step of updating comprising: advertising said field value uto adjacent nodes, measuring an environment parameter ω from the environment of the node, receiving field values uof the said adjacent nodes, recording the field values u, calculating a new field value ufrom the field value u, the field values uof the adjacent nodes and the environment parameter ω in such a way that field values of nodes whose environment parameter ω are within a constant range agree with given distribution, deleting the previous field value u, and recording said new field value u.
