Composite Service Adaptation Supported Environmental Monitoring System

In the research of composite service execution, runtime QoS ensuring of composite service is an important problem in composite service adaptation. This paper gives an introduction to the design and implementation of composite service adaptive execution supported environment monitoring system, analyzes the crucial problem of the system, builds up an experiment environment to test the monitoring system which is implemented. The result shows that this system can satisfy the requirement of supporting the execution of composite service adaptive, can provide information to composite service execution engine about the change of service execution time according to the change of environment, and provide decision evidence to composite service adaptation action.
