Mobile IP is the most widely known mobility management scheme in wireless networks. However, some inherent drawbacks of this protocol are partially solved. Although Route Optimization tries to solve these problems, it cannot manage mobility binding efficiently. In this paper, three mobility binding management schemes, including Always Push Scheme, On Demand Scheme, and Threshold Scheme, are proposed, evaluated and compared. The simulation results show that the mobility binding updating strategy significantly impacts the overall performance of mobile systems. Threshold Scheme proposed in this paper outperforms both the Mobile IP and Route Optimization for mobility management in IP based networks.
