Abstract

In this paper we study hexagonal interconnection net works. A convenient addressing scheme and routing algo rithm are proposed. It is the first addressing scheme as suming both the unicity of the coordinates for each node and a distance formula between two nodes. We continue by developping an optimal routing algorithm based on the distance formula in order to use shortest paths from the source to the destination node. Our results are obtained with the help of the one-to-all and all-to-all algorithms de scribed in [6].
