Enhancing PTN to Improve the QoS Provided by the IP Mobility Management.

The integration of Mobile and Fixed Network is one of the most important topics in the Future Internet development and an open issue for network providers. In this case, mobility management and Quality of Service (QoS) are two of the main goals in this integration. These tasks are an important challenge if the mobility rate is very high. In this paper, we present a new architecture to provide both of them, QoS and high rate mobility using an IP-based mobility protocol and an MPLS-based protocol to deploy Packet Transport Networks (PTN). To achieve this, we had developed analytical models to evaluate registration updates cost, packet loss rate and buffer requirements of the architecture. Numerical results show that the proposed mechanisms can significantly reduce registration updates cost and provide low handoff latency and packet loss rate under various scenarios.
