Multicast broadcast services support in OFDMA-based WiMAX systems [Advances in mobile multimedia]
Multimedia stream service provided by broadband wireless networks has emerged as an important technology and has attracted much attention. An all-IP network architecture with reliable high-throughput air interface makes orthogonal frequency division multiplexing access (OFDMA)-based mobile worldwide interoperability for microwave access (mobile WiMAX) a viable technology for wireless multimedia services, such as voice over IP (VoIP), mobile TV, and so on. One of the main features in a WiMAX MAC layer is that it can provide'differentiated services among different traffic categories with individual QoS requirements. In this article, we first give an overview of the key aspects of WiMAX and describe multimedia broadcast multicast service (MBMS) architecture of the 3GPP. Then, we propose a multicast and broadcast service (MBS) architecture for WiMAX that is based on MBMS. Moreover, we enhance the MBS architecture for mobile WiMAX to overcome the shortcoming of limited video broadcast performance over the baseline MBS model. We also give examples to demonstrate that the proposed architecture can support better mobility and offer higher power efficiency

Guest Editorial: Satellite Systems, Applications and Networking.
yesGuest Editorial of Special Issue (featuring eight original papers, comprising 133 pages in total). Whilst satellite systems continue to be at the forefront of broadcast communication
service provision, they have an increasingly important role to play in the provision of
global Internet services. There has been a strong trend towards convergence of
communication services in recent times, with the Internet providing the ideal platform
on which to base such convergence. Even traditional circuit-switched applications
(such as voice and video streaming) have been shown to work effectively over the
Internet. Although the Internet is prevalent in the developed world, satellites are vital
to extending this into more remote and sparsely populated regions of the world. It is
therefore important that satellite technology is advanced to provide seamless
interoperability with the Internet and adequate Quality of Service (QoS) support. The
purpose of this special issue is to present research devoted to furthering satellite
technology and networking to support the provision of both current and future
applications

Editorial: Special Issue on Recent Advances in Computer and Communication Networks Technology
Dramatic improvements in networking technologies over the past couple of decades have yielded substantial increase in computer and communication capabilities. A number of new networking technologies such as middleware, wireless mesh networks anWiMAX, global IPv6, new generation multimedia, and modern network security started taking off. To date, some of these development efforts have mainly focused on protocol standardization, product development, and network operations besides being research targets. We believe that the accumulated experience in new networking practices now provide interesting research opportunities, not only for the broader network research community, but also for those who have been involved in these advancement developments
