In this study, we aim to improve the faulttolerant routing algorithm in dual-cubes. The dual-cube is a topology developed by extending the hypercube. The dualcube can interconnect the same number of nodes as the hypercube with almost the half number of edges. The faulttolerant routing methods in dual-cubes proposed by previous works give priority to the preferred neighbor nodes, and forward the message to one of them. Therefore, in case where it is necessary to forward the message to one of the spare nodes to establish a fault-free path to the destination node, the routing fails. Hence, we tried to improve the performance of the fault-tolerant routing method by modifying it. In our method, each node calculates additional information if its cross-edge is faulty or not, and exchanges the information with its neighbor nodes. We also modified the fault-tolerant routing algorithm so that it can make use of the information regarding the cross-edges of the neighbor nodes. To evaluate our method, we conducted a computer experiment in which we compared it with the methods by previous work from the viewpoints of the ratio of successful routings and the ratio of the detours. As a result, our method showed better performance than the methods by the previous works.
