Abstract:

The description of resources needs to consider the integration of three aspects,viz.property,capability and status, especially in the environment of InternetofThings where the users concern about capabilities of resources and description of status much more.So far as we know,most researchers have laid emphasis on the descriptions of information resources mostly based on property description rather than capabilities,status and QoS of resources. In order to overcome the weakness of current methods,we introduce QoS parameters of resource to build a resource capacility mode  based on the descriptions of actions.The paper proposes a resource matching method BQRM with QoS assessment,and constructs a four step matching mechanism with QoS assessment.At last,the experimental analysis validates the advantages of the capabilities of entity resources modeling and resource matching method with QoS.
