A QoS-Support Mobility Management Approach in Wireless Network

Design of mobility management protocols stands out as an important challenge in integrating wireless networks into the IP-based Internet, especially when such networks are deployed for real-time applications. We present a new hierarchical model for intra-domain mobility management with QoS support for the wireless access network. The scheme includes an anchor selection algorithm with QoS support, and efficient techniques for intra-anchor handover, inter-anchor handover, and paging management. In addition to QoS support, the proposed scheme has the advantages of robustness, scalability, load balancing and fast handover. Simulation results of our model indicate that it provides good handover performance in the presence of multiple QoS classes of applications.
