IEEE802.16 is a promising wireless broadband technology for the next generation last mile access. Though Quality of service (QoS) is guaranteed by the standard which defines five types of multimedia traffic classes, it doesn't define any specific admission control strategy and scheduling algorithm which are left to venders to design, and they have been becoming the research hotspot and many manufacturers,...
The next generation of wireless networks, as envisioned by recent advances in cognitive radio (CR) technologies, will be intelligently adjust their configuration to changes in the communication environment. Reconfigurability is set to be an important facet in the evolving world of mobile and wireless communications, through which technologies such as cognitive radio are greatly facilitated. In next...
The 3GPP specifies the IP multimedia subsystem (IMS) to provide several kinds of multimedia services in UMTS Release 5 and later releases. Interworking at the service layer between 3GPP and Wimax networks requires interworking between IMS functionality. By studying several interconnection scenarios and the main functionality of IMS, this article analyzes how the interworking of 3GPP and Wimax networks...
