Research on Task Scheduling Algorithm Based on Multi-attribute Constrains in the Environment of P2P Network
To improve the task scheduling efficiency of peer-to-peer network environment,task scheduling algorithm MDSA(integrating Multi-resource attribute with Deadline Scheduling Algorithm) is proposed.In the implementation process of the algorithm,dividing P2P network environment into different virtual communities based on the attribute of the membership function,and submitting different type tasks to correlative needs virtual communities.Peer to peer network is Abstracted as a collection of resource attribute,and collection of tasks is defined.On the basis of multi-attribute constraints,producing the scheduling queue according to deadline and location of the node information,scheduling task by means of two level scheduling ideas and prediction mechanism.MDSA scheduling algorithm was tested by applying NS2 and GridSim toolkit.The simulation results show that algorithm MDSA is superior by comparing and analyzing the result results.
