NS2 based simulation software for the integration of MPLS with mobile IP

The MPLS module and IP micro mobility module are not integrated in recent simulation tool.A simulation tool is required in research into the integration of MPLS with Mobile IP. In this paper,the authors propose a way to support hierarchical address in MPLS module in order to support the simulation. Those main modified parts of MPLS module and IP micro mobility module in NS2 platform are also discussed.
