Trust mechanism-based dynamic task scheduling in grid computing
网格计算中基于信任机制的动态任务调度

A kind of trust mechanism-based dynamic task scheduling model was presented,which collected and feeded back resource information through the use of MDS and NWS.It imported trust mechanism by using interpersonal trust relationship in human society for reference,and adopted the method of DSRL(Dynamic Self-adaptive distributed Replica Location method) for the management of data repository and the method of dynamic transfer for the tasks in the trouble nodes.For the task scheduling strategy,the Min-min algorithm was modified and the Trust-Min-min algorithm was proposed which enhanced the validity of grid computing.At last this algorithm was simulated with the aid of SimGrid toolkit and it was proved reasonable and efficient.
