Mobility Management Protocols for Wireless Mobile Networks
4 G wireless networks are envisioned to provide high raw data rates in the downlink as well as in the uplink directions. These networks are driven by the need to support context-rich multimedia services and applications. 4G wireless networks also support global roaming and multiple classes of services with variable end-to-end QoS requirements across heterogeneous wireless systems. Mobility management became an important issue since when the mobile devices are become more and more popular. This paper gives an overview of mobility management in mobile network which includes the concept of location management and handoff management. An introduction to different mobility management models are defined that can be used for micro and macro mobility solutions.
