Cooperative Agent-Based QoS Framework for Heterogeneous Networks

With the fast development of network technology and expansion of the network scale, the heterogeneity of Internet makes the Quality of Service (QoS) guarantee techniques even more challenging. In this paper the state-of-the-art of QoS guarantee techniques is first reviewed, and a new Cooperative Agent-based QoS Framework (CAQF) for heterogeneous networks is proposed, which integrates the technologies of QoS-adaptive cooperation, situation awareness, admission control, routing, packet scheduling and resource management. It can be used for intra-domain, inter-domain's QoS guarantee in the heterogeneous networks. Procedure simulation results show that CAQF can achieve expected functionality, while demonstrating the feasibility and universality of the framework for distributed end-to-end QoS cooperation.
