Quality-of-service management for IP-based mobile networks

Efficient support for multimedia communication is essential for next generation mobile wireless networks. In order to provide the necessary quality-of-service (QoS) in mobile wireless networks, appropriate signaling has to be defined. Our QoS signaling architecture integrates resource management with mobility management. It is based on a domain resource manager concept and nicely supports different handover types. In particular, our approach supports anticipated handover with pre-reservation of resources before the mobile node is attached to the new access point. The article discusses the protocol design and implementation, in particular integration with mobile IP, and shows the benefit of anticipated handover by measurement results.
