Because of user mobility, highly dynamic, error-prone wireless channels, the QoS control for mobile Peer-to-Peer (MP2P) streaming media has to face considerable challenges. Given to the advantages of policy management, we develop a policy-based QoS control (PBQC) architecture to provide QoS assurance dynamically and automatically in mobile network environment. And we also propose a MP2P streaming...
As integration of heterogeneous networks has become one of the most important characters for next-generation networks, it becomes a very challenging issue to ensure effective handoff when mobile node moves between different heterogeneous networks. In this paper we propose an effective handoff mechanism based on location information. By processing geographical data (consisting of information about...
According to the interworking authentication trends, this paper has proposed a novel reference of interworking AAA architecture among 3GPP, WiMAX and WLANs. Moreover, based on the proposed architecture, a hierarchy AAA mobility management architecture is brought forward, as well as a dynamic reorganizing management scheme authentication domain. Finally, the simulation results show that the total cost...
