This paper proposes a QoS micro-mobility solution capable of providing QoS support for global mobility. The solution comprises enhancements with regards to the mobility management of Mobile IPv6 (MIPv6) and in the resourcemanagement of the Differentiated Services (DiffServ) QoS model. The mobility management of MIPv6 was extended with fast and local handovers in order to improve its efficiency in high dynamic micro-mobility scenarios.The DiffServ resource management was extended with adaptive and dynamic QoS provisioning in order to improve resource utilization in mobile IP networks. Furthermore, to improve resource utilization, the mobility and QoS messages have been coupled so that resource managementable to proactively react to mobility events can be attained.The performance improvement of the proposed solution inaddition to the model parametrization have been evaluated using a simulation model. Simulation results indicate that the solution avoids network congestion as well as the starvation of DiffServ classes of a lesser priority. Moreover, the results also indicate that bandwidth utilization for priority classes increased. The QoS offered to MN’s applications, in each DiffServ class, remained unchanged with MN mobility.
