With the rapid development of e-commerce and the expansion of e-commerce system scale, scalable trust in e-commerce becomes critical. This article examines scalable trust of multiagent e-commerce system (MECS) and proposes a fuzzy model for scalable trust in e-commerce. It also discusses the realization of scalable trust from the viewpoint of engineering. The proposed approach will facilitate research and development of trust, multiagent systems, e-commerce and e-services
Intelligent management to the large scale Ad Hoc network has already become a kind of trend, and the clustering algorithm is the key. This article examines formula factors and their mutual relations of EWCA algorithm weights. After considering complex external environment of nodes, digging factors of network, it proposes an algorithn that calculates, sets and adjusts these weights by comparing weights, efficent-weights and expecting-weights, so as to fit for all kinds of application environment. The algorithm does not only guarantee the rational and effective weights, but also run in a human friendly manner.
