Abstract In the near future, wireless networks will certainly run real-time applications with special Qual-ity of Service (QoS) requirements. In this context micro mobility management schemes such as Fast Handovers over Hierarchical Mobile IPv6 (F-HMIPv6) will be a useful tool in reducing Mobile IPv6 (MIPv6) handover disruption and thereby to improve delay and losses. However, F-HMIPv6 alone does not support QoS re-quirements for real-time applications. Therefore, in or-der to accomplish this goal, a novel resource manage-ment scheme for the Differentiated Services (DiffServ) QoS model is proposed to be used as an add-on to F-HMIPv6. The new resource management scheme com-bines the F-HMIPv6 functionalities with the DiffServ QoS model and with network congestion control and dynamic reallocation mechanisms in order to accom-modate different QoS traffic requirements. This new scheme based on a Measurement-Based Admission Con-trol (MBAC) algorithm is effective, simple, scalable and avoids the well known traditional resource reservation issues such as state maintenance, signaling overhead and processing load. By means of the admission evalu-ation of new flows and handover flows, it is able to pro-vide the desired QoS requirements for new flows whil
