A study on the efficiency of the object model utilizing CORBA for middleware development in NS-2

Abstract

An apparent constraint on the Network Simulator (NS-2) is that it does not currently allow for dynamic interaction between itself and the users while a network simulation process is running. Having realized the advantages of NS, it is interesting to investigate the feasibility to develop a mechanism that would enable the dynamic interaction between the users and NS itself. This paper is focused on proposing the utilization of CORBA to develop a middleware having the dynamic interaction mechanism for NS-2. With CORBA having the overall view of the programming realm as individual objects allowing for interoperability, it offers the possibility to observe NS procedures and algorithms as objects and allow for a remote CORBA client to access these objects to be operated on without the direct access to the NS core itself.
