Design and Implementation of Media Independent Handover on Heterogeneous Wireless Networks

Due to the great promotion of wireless network access technologies, users in different locations may be covered by different wireless access networks. It is more desirable to integrate heterogeneous access network technologies in multi-mode network devices for users. Te IEEE 802.21 working group defined a framework to provide The Media Independent Handover Functions (MIH Functions) to achieve handover with better performance. However, most implementations of IEEE 802.21 were based on mobile IP. The cost of implementation of IEEE 802.21 is high. In this project, we design and implement the MIH Functions by low-cost approach within Wi-Fi and Bluetooth. We can provide seamless handover to users such that user can switch access networks within Wi-Fi and Bluetooth with low cost.
