MCORBA-DESIGN AND IMPLEMENTATION OF CORBA BASED ARCHITECTURE TO HANDLE MOBILITY

Abstract

In recent years, two noticeable areas of growth in the computer industry have been the number of distributed applications being built using Object Request Broker (ORB) and the rapid growth in the area of mobile computing. These ORBs are implementation of Object Management Group's (OMG) Common Object Request Broker Architecture (CORBA). CORBA defines a framework for developing object-oriented distributed application. The OMG has specified a protocol to allow ORBs to interwork, called the Internet Inter-ORB Protocol (IIOP). Current CORBA technology, including the IIOP protocol, is not designed for use in a mobile environment. Using CORBA in a mobile environment raises a number of problems due to hardware mobility and characteristic of wireless networks. This dissertation identifies and discusses the problems due to mobility in CORBA and describes the design and implementation of our architecture for Mobile CORBA (MCORBA). MCORBA allows CORBA clients running on mobile devices to communicate transparently with CORBA objects hosted by the fixed hosts.
