Efficient Handoff Management in WiMAX Networks for Mobile Nodes

This paper discusses a streamlined approach to handoff management in WiMAX networks for mobile nodes. When a mobile node transitions from one base station (BS1) to another (BS2), the Mobile IP (MIP) agent registers the DHCP request, obtaining an IP address from the IP Address Manager without changing the node's address. The establishment of an IP tunnel between two MIP agents routes packets seamlessly. Additionally, an OpenFlow router manages dual IPv4 addresses, ensuring smooth transitions for efficient connectivity. This method enhances network performance and user experience.

  2. One Interface Mobile Node IP Address Manager Subnet 2 BS2 • Handoff from BS1 to BS2 • MIP Agent picks up DHCP request • Obains address from IP Address Manager and gives it to Mobile Node (no change in address) • IP Tunnel between two TMIP agents established • Packets routed through tunnel MIP Agent Mobile node MIP Agent Subnet 1 BS1 Corresponding Host

  3. Handoff with OpenFlow Router Subnet 1 BS1 • Mobile node has two IPv4 address: • NIC IP and Permanent IP • OpenFlow Router rewrites Permanent IP destination address to NIC IP as destination • OpenV controller at mobile node rewrites NIC IP to Permanent IP Mobile node OpenFlow Router To Internet Subnet 2 BS2
