Blockchain-Based NAT Management for Smart Mobility

Abstract

Network Address Translation (NAT) devices are commonly used to extend internal private addressing from the global public IP addressing. Most mobile devices usually use the vertical model to handle NAT and mobility management. The goal of this paper is to propose a blockchain-based smart NAT management scheme to overcome the limitation that the vertical model faces in relation to NAT and mobility management. Our proposal focuses on the idea that, if we use the blockchain technologies, each peer can easily agree on the necessary parameters required to handle the complicated NAT and mobility management procedures.
