Adaptive Optimization and Simulation of Mobility Management in IPv6 Network |
| |
Abstract: | The recent emergence of mobile communication and wireless access in IP network provides an incentive for designing an efficient mechanism to enable an IP terminal to move seamlessly among wireless and wired networks with different prefixes. Mobile IPv6 shows some new key features and will be accepted more widely than Mobile IPv4 in several years later. Decreasing mobility management cost is one of the key problems on designing Mobile IP. Hierarchical Mobile IPv6(HMIPv6) was proposed to reduce the number of management messages in core network. However, after comparing the cost of HMIPv6 with MIPv6, this paper proves that the performance improvement of HMIPv6 is at the expense of the increase of cost inside hierarchical domain. For supporting more flexible and effective mobility, Adaptive Mobility Management Scheme(AMMS) is proposed in this paper. AMMS allows a mobile node to select a suitable mobility management mechanism adaptively according to some parameters. Simulation work is accomplished and the results show that AMMS has better performance than unmixed MIPv6 and HMIPv6 on decreasing the total communication and management cost. |
