An End-to-end Qos Provisioning Architecture in Mobile Network

Quality of Service (QoS) provisioning is one of critical issues in the wireless and mobile network. However, the existing works for QoS guarantee focused on only the wireless network characteristics. In this paper, we proposed an end-to-end QoS provisioning architecture in the diverse mobility situations. This architecture consists the Differentiated Service (DiffServ) model and Integrated Service (IntServ) model. We use service level agreement and the tunneling in DiffServ region for QoS provisioning in macro mobility and proposed a multiple paths reservation scheme using Resource Reservation Protocol (RSVP) for QoS guarantee in micro mobility The architecture can meet the end-to-end QoS specification for the mobile hosts. Furthermore, it is so flexible and scalable that it can be utilized as the QoS model in the next wireless and mobile networks.
