Dynamic Methods of Trust-Aware Composite Service Selection
Wang Yong · Chinese Journal of Computers · 2009
Trust concept and Trust Degree are introduced into service composition and trust-aware service selection problem in service composition is discussed.The mathematic models based on two opinions are established.Based on opinion 1,the dynamic selection problem of service composition is researched deeply.Two dynamic selection methods are designed based on ant colony system:method 1 is under the environment of service providing perfect service without exceeding threshold and rejecting service with exceeding threshold;method 2 is under the environment of service's QoS descending when the invoke number increase.The tow methods have good effect through experiments and experiment results analysis.
