Inter-Domain handover based on Blockchain for SDN-based Network Mobility

Software-Defined Networking (SDN) enables network operators to quickly implement new services and adapt to their needs. The emerging SDN architecture can provide a new direction for dealing with mobility management challenges. This paper introduces a blockchain-based inter-domain mobility management solution. This solution enables efficient and flexible mobility management for mobile networks, accommodating a variety of network technologies while ensuring optimized and effective data routing to the intended destination. In the evaluation, we present an analytical evaluation of signaling cost. The numerical results demonstrate that SDN-NEMO can provide lower costs and an optimal route for the mobile network.
