A Resource Entity Model Oriented Mobile Collaboration Environment

In order to aggregating the highly dynamic user resource in mobile collaboration environment, a REM model was proposed. Resource entity model (REM), which is an abstactive logic unit packaged a speicific resources and related computing. It has not only the common semantic and characters of resources, but also dynamic behavior characters of resources. At first, the semantic and characters of resources in mobile collaboration environment were anlysised. Then, definition of mobile collaboration resource was given based on it. After that, the concept of resource entity (RE) was introduced into description for mobile collaboration resources, and the REM model was constructed. Fol-lowly, the basic idea and method of varified the correct of semantic and character on REM was done by using CPN tool. With full consideration about the highly dynamic and complex characters of mobile collaboration environment, having changed the resources from passive to active and from static to dynamic, the REM fits the mobile collabora-tion environment better than other existing resource model. It can enhance the utilization of the user resources.
