The main aim of the research presented in this paper was to investigate ＇how to reduce the bluetooth discovery time in collaborative middleware based collaborative working environment （CWE）, to enhance the communications of mobile users. The high level collaborative middleware is a research and technology development （RTD） challenge and one of most desirable medium to long term research outputs for CWEs. This research activity outlines a collaborative middleware module that has been developed on Smartphone technology and enables to reduce the discovery time of a multi-user collaborative working environment via a Bluetooth wireless communications network. To achieve this aim, it started with discussing the key design parameters, and then the design of collaborative middleware module with collaborative functionality; finally it is a comparison test to evaluate the impact of middleware. The result of the evaluation concludes the Bluetooth enabled collaborative middleware can reduce the discovery time in CWE.
