A Grid Trust Audit Model Based on QoS
QU Wei-li · Microcomputer Information · 2010
Trust value of the grid resource granted by the trustor has character of subjective at present research. In this paper, a grid trust audit model based on QoS is presented.It is proposed that basic trust value function be constructed based on the QoS constraints that the services provide,and that in the process of building the basic trust value function,a partial relation is inducted in order to remove the worthless history information.After that,the audit for trust value come from trustor is made and adjust the trust value of grid resource. Finally we performed simulation to compare the performance of the trust model based on the audit with traditional trust model.The experiments show that the trust model based on the audit is efficient on improving the reliability of trust value and task fulfilling ratio.
