Examining the Effects of Trust on a Service Network

This paper attempts to quantify the effects of trust on the network performance and structural evolution of a service network to further apply trust to cooperation among individuals.Based on an existing service network model,two different strategies for partner selection,i.e.,trust-based and random are devised,and their effects are observed.Experimental results show that the network with the trust-based strategy can accomplish various services with a higher probability,compared with the network with random strategy.Moreover,the trust-based partner selection can make the network quickly converge to an equilibrium state,i.e.,the values of its structural characteristics remain stable.
