Abstract: This thesis proposes and evaluates an end-to-end QoS architecture for mobile hosts that combines IntServ/DiffServ, MIPv6 and IEEE802.11e. IntServ provides per-flow QoS while DiffServ provides aggregate QoS. IEEE802.11e provides QoS support at the MAC layer of IEEE802.11-based WLANs and IPv6 has built-in capability to support IP level mobility (MIPv6). In this thesis, we use IntServ at edge networks, DiffServ at core networks, and IEEE802.11e at the wireless last hop to provide end-to-end QoS for mobile hosts. Moreover, one approach is proposed to improve the handoff performance, which is assigning Router Advertisement messages of MIPv6 higher priority. We combine this approach with the approach that the mobile node sends Binding Update messages of MIPv6 to the previous base station that it just visited to improve the handoff performance of the proposed QoS architecture. Simulation results show the achievable end-to-end QoS and improved handoff QoS of our QoS architecture.
