This paper aims to find the most optimal Grey-Fuzzy routing algorithm within multinomial time about the NP-complete problem of multi-objective optimization QoS routing. With the help of Grey-Fuzzy theory, this algorithm achieves an O(mn) time complexity through integrating the QoS metrics to a Grey-Fuzzy synthetic attribute according to its membership degree and grey degree. Our algorithm can use...
NGI (next generation Internet) needs to provide QoS (quality of service) routing and support ABC (always best connected). However, due to the difficulty on the exact measurement of the network status and the exact expression of the user QoS requirements, QoS routing scheme with ABC supported should be based on the fuzzy information. Meanwhile, with the gradual commercialization of the network operation,...
This paper proposed a dynamic fuzzy clustering scheme with adaptive fuzzy threshold to the hierarchical topology optimization in overlay multicast. The scheme firstly normalized the two routing metrics - overlay path delay and overlay node access bandwidth-- to comprise the clustering feature vector, and then calculated the Euclidean distance within each pair of overlay nodes to construct the fuzzy...
