Abstract

This paper presents a new object model, LOM (Lightweight Object Model) and an implementation method for the distributed trader in heterogeneous distributed computing environment including mobile network. Trader is a third party object that enables clients to find suitable servers, which provide the most appropriate services to clients in distributed environment including dynamic reconfiguration of services and servers. Trading service requires simpler and more specific object model than generic object models which provide richer multimedia data types and semantic characteristics with complex data structures. LOM supports a new reference attribute type instead of the relationship, inheritance and composite attribute types of the general object oriented models and so LOM has simple data structures. Also in LOM, the modelling step includes specifying of the information about users and the access rights to objects for security in the mobile environment and development of the distributed storage for trading service. Also, we propose an implementation method of the distributed trader, which integrates the LOM-information object model and the OMG (object Management Group) computational object model.
