In cellular network,frequency must be assigned to call requests and the frequency number of the whole network is minimized.An efficient frequency assignment algorithm is described based on a triangular lattice-mobile communication network.The algorithm is distributed:each cell server will need only a limited exchange of information with cells in its proximity to make decisions on its frequency assignment,and the computation has relative independence.
