Dynamic Service Composition: a Collaborative Resource Sharing Framework for Equipment Grid

To get the distributed and autonomous equipments in equipment grid(EG) work collaboratively to serve users as a "supper virtual equip", "dynamic service composition (DSC)", a five-layered implemental framework is put forward. Via solving the sub- problems in each layer, simple services from local equipments are combined into complex ones to realize the collaborative sharing. And an EG prototype has been established based on DSC.
