Quality of service and security as frameworks toward next-generation wireless networks

This article aims to analyze quality of service (QoS) and security as frameworks toward next-generation wireless networks. QoS, security and mobility can be viewed as three different indispensable aspects in 4G networks. However all are related to networks nodes involving the controlling or the processing if IP packets for end-to-end flows between a mobile node (MN) and its corresponding node (CN). The goal is to present network mobility issues and requirements in the context from beyond 3G (B3G) toward 4G networks. Finally, as an example soft handover of streamed multimedia in 4G networks is invoked in order to enable the MN to control the handover. Also it is shown that there is no modification to the existing architectures of wireless network, where this handover is used.
