The low bandwidth hinders thedevelopment of mobile computing. Besides providing relatively higherbandwidth on communication layer, constructing adaptable upperapplication is important. In this paper, a framework of auto-adaptingdistributed object is proposed, and evaluating methods of objectperformance are given as well. Distributed objects can adjust theirbehaviors automatically in the framework and keep in relatively goodperformance to serve requests of remote applications. It is an efficientway to implement the performance transparency for mobile clients.
