In this paper, we introduce a dynamic anchor based mobility management scheme for mobile networks, in which different hierarchies are dynamically set up for different users and the multiple tunnels are converged into a single tunnel when lifetime refreshes without excessive packet loss. To justify the effectiveness of our proposed scheme, we made an analytic model to evaluate the signaling cost and handoff delay compared with legacy schemes. Our performance result shows that the proposed dynamic anchor based mobility management scheme can reduce the system signaling cost and has shorter handoff delay under various scenarios.
