Recently, Mobile IP has been widely used to support seamless Internet user mobility. However, unnecessary registration process of Mobile IP system for tracking mobile users' movement causes large increase of signaling costs, and affects the scalability. Therefore, it is necessary to investigate how to reduce the signaling costs in Mobile IP. This paper proposes a Two-Step Paging Scheme for Mobile IP (TSP-MIP) to reduce signaling costs and the sensitivity of the system with various user parameters. The main concept is to partition the paging area and select the optimal paging sequence. The performance of the proposed TSP-MIP is compared with three conventional schemes, namely, Distributed Local Paging scheme for Mobility Management in Mobile IP (DLP-MIP), Paging. Extensions for Mobile IP (P-MIP) and Mobile IP via analysis and simulation results. The reported results show that the total signaling costs of TSP-MIP is the lowest, compared with those three conventional schemes.
