Abstract
In this thesis, we propose a new micro-mobility management scheme, called Micro Mobile MPLS, that supports both mobility and QoS management in wireless networks. Our approach relies on integrating the Mobile IP Regional Registration and MPLS protocols. The major strength of our proposed scheme is its ability to support both the fast handoff and QoS via traffic engineering path and also to reduce the total signaling cost by controlling dynamically the number of registration updates with the root of the domain. Three protocol variants are then defined. In the first variant (FH), we consider the fast handoff mechanism, which anticipates the LSP procedure setup with an adjacent neighbor subnet that an MN is likely to visit. In the second variant (FC), the forwarding chain concept, which is a set of forwarding path, is provided to track efficiently the host mobility within a domain. Finally, the third protocol variant (MFC) aims to reduce the total signaling cost by controlling dynamically the number of registration updates with the root of the domain according to a cost comparison and using the mobility characteristics of users and network environments. In order to assess the efficiency of our proposals, all underlying protocols are compared through analysis and simulations. Analytical models using Markov chains are developed to evaluate the handoff latency, the link usage and the signaling cost function for both two-dimensional (2-D) and one-dimensional (1-D) mobility models. Numerical and simulation results show that the proposed mechanisms can significantly reduce the registration updates cost and provide low handoff latency and packet loss rate under various scenarios.
