Mobility support in IPv6 networks with Dynamic DNS servers

MEPv6 (Mobile IPv6) is considered a foundational technology for a ubiquitous network, available anytime and anywhere to users of mobile terminals. However many problems remain, making HA (Home Agent) a point of failure for handover procedures, and producing handover delays that can degrade the quality of communication for real-time applications. The authors proposed an improved handover procedure in which a DDNS (Dynamic DNS) server notifies a BU (Binding Update) message to CNs (Correspondent Nodes) without authentication via HA, but the method also incurred long handover delays and a large packet loss rate. This paper proposes a new mobility support procedure in IPv6 Networks with DDNS servers, which no longer supports MIPv6. Simulation experiments show that handover delays and packet loss rates are reduced, relative to our previous proposed handover procedure and MIPv6.
