A QoS Framework for Heterogeneous Wireless Networks using a Multiagent System

Thus, current and emerging wireless technologies will belong to a multi-tier system that will interoperate with different wired backbone networks and will have to provide Quality of Service (QoS) guarantees. The asymmetrical nature of the traffic, the handover support, the different access devices and the sparse standardization of QoS parameters are some of the known problems in heterogeneous wireless networks. In this paper, we propose a multiagent system that will improve the mapping of parameters between heterogeneous networks, call admission control and handover management. The objective is to guarantee end-to-end QoS.
