Abstract

The concept of routing capability is proposed to assist fault-tolerant routing in hypercubes. Routing capability is defined with respect to the entire spectrum of distance. As a result, the amount of information that is useful for message routing is increased. An algorithm is presented to facilitate efficient fault-tolerant routing of messages. The algorithm routes a message in an attempt to minimize derouting. Furthermore, the concept of directed routing capability which contains more useful information for fault-tolerant routing is introduced. Simulation results demonstrate the usefulness of our approach.
