Physical and logical mobility of CORBA servants under intermittent connectivity nomadic environments

Abstract

In a wired environment, object-oriented middleware facilitates the development of distributed objects. Common Object Request Broker Architecture is a prominent example of object-oriented middleware. As a joint effect of advancement in electronics and telecommunication manufacturing segments and tremendous increase in the demand of new class of services from mobile devices by mobile device users, middleware technologies can empower mobile devices by providing significant platform for many services. Object-oriented middleware are not inherently designed to support wireless environment behaviour. The aim of this research is to investigate the issues of the Object Management Group’s Common Object Request Broker Architecture (CORBA) to facilitate application-to-application communication in wireless environment where connectivity is intermittent. The dissertation discusses the issues in the design and implementation of architecture where CORBA objects have migrating behaviour and host incarnating the CORBA objects are also mobile devices in nature.
