Abstract: Huge amounts of data in a cloud computing environment scheduling process,the use of data nodes exist strong randomness.Traditional scheduling method is easy to cause data node conflict,leading to the scheduling efficiency lower.Based on data node to avoid conflict of huge amounts of data efficiently scheduling method in cloud computing environment.The whole scheduling tasks into subtasks,each subtask quantity calculation,according to the target data in data transmission of a node,the data node quota calculation,according to the calculation results,establishing optimized scheduling model huge amounts of data in cloud computing environment.The experimental results show that the improved data scheduling algorithm in cloud computing environment,can effectively improve the efficiency of the scheduling,to avoid the data conflict situations.
