A Scalable Mobility Management Scheme for PMIPv6 with Multiple Control and Data Plane

Distributed Mobility Management (DMM) is an alternative to Centralized Mobility Management (CMM) schemes. In DMM, signal and data forwarding functionalities are separated into control and data planes. Although, such separations are beneficial to handle densely populated users and voluminous data, it fails to address scalability issue. Researchers suggest to deploy multiple control planes to handle signalling load in densely populated network. But these schemes are not suitable to process voluminous data. In this paper, we propose a DMM framework by deploying multiple instances of control and data planes to handle densely populated network with voluminous traffic. We suggest two algorithms for selecting control plane and data plane for visitor mobile nodes in a foreign network. Performance parameters like convergence time of proposed algorithms, domain capacity, handoff latency and packet delivery cost are examined analytically and verified with ns−3 simulations. Results are compared with Proxy MIPv6 (PMIPv6) and Distributed-PMIPv6 (D-PMIPv6) protocols. Observations reveal that proposed DMM solution significantly outperforms the above stated benchmark approaches.
