Security Enhancement for IP Network Integration with Mobile IP Based Communication

Abstract

Mobile IP communication mostly exist in wireless networks where users need to carry their devices across several networks within different IP address. Mobile IP is enabled and supported by mobile devices like Cellular phones, Personal Digital Assistances, Global Positioning Systems, and handheld devices which have been developed rapidly and their communication capabilities are enhanced effectively. These devices allow users freedom of movement and to access internet services in any location. Now days, enterprises are deploying Mobile IP services to enable their usersto access the enterprise services while the user is in mobile mode. The challenge in such scenario, deploying Mobile IP for accessing enterprise services with mobility, security of intermittent connection is the first challenge to be addressed. In this study, alternative methods for securing and enhancing the connectivity of mobile nodes that uses Mobile IP for communication and accessing enterprise services in mobility mode. When the mobile nodes with Mobile IP needs to access the enterprise services in mobility mode, the persistence connectivity to the home networkwhere the enterprise services are provided is the backbone for secured service access. To create secure and persistence connectivity, the role of routing algorithms and mobility models are assessed in two different scenarios. The first scenario is integration of mobile node that uses Mobile IP when it gets away from the home network. The second scenario is integration of Mobile Ad hoc networks that implement Mobile IP to access enterprise services using the enterprise IP network. The evaluation result of the efficiency of the routing algorithm and the mobility models are assessed in terms of the network throughput in the communication. The results shows that routing algorithms and mobility models has great impact on the integration of Mobile IP networks and regular IP network communication.
