| Mobile IP is currently one of the most important protocols for next generation mobile Internet that allows users to maintain connectivity while roaming in IP networks. Mobile IPv6 (MIPv6) provides many features such as sufficient address space, mobility, security and QoS. RSVP is a well mature protocol for reserving, network resources to support QoS requirements between sender and receiver(s). RSVP was originally developed for fixed networks and when combined in mobile environments using Mobile IP as the mobility management protocol several issues arise in terms of QoS deterioration.; To reduce these inefficiencies, our objective is to propose a new RSVP extension sender oriented to support real-time service in Hierarchical Mobile IPv6 environments with Fast Handovers (Fast Mobile IPv6). Our scheme integrates RSVP based sender oriented with Mobile IP regional registration and Fast Handover principles and makes advance resources reservation when an intra-site handoff may possibly occur.
