Challenges and Issues in 4G - Networks Mobility Management
Wireless broadband technology is now in motion to provide higher data rate, wider coverage and improved mobility. Towards this, the 4G-network is an integration of various wireless technologies and expected to provide seamless mobility. Moreover 4G-networks will be entirely packet switched systems based on IP protocol. One of the research challenges for 4G-Network is the design of intelligent mobility management techniques that take advantage of IP-based technologies to achieve global roaming among various access technologies. Hence Mobile IPv6 is considered to be one of the key technologies for integration of heterogeneous networks.
