SERVICE-ORIENTED BROADBAND WIRELESS NETWORK ARCHITECTURE

n the past few years, broadband wireless networks have been very attractive as a key technology for providing Internet access because of quick and cost-effective deployments. In addition to the features of high data rate and large coverage, broadband wireless networks also promise to rapidly provide access to locations in the world’s rural and developing areas where broadband is currently unavailable, as well as compete for urban market shares. Till now, most existing efforts have been focused on basic access capability. However, to successfully operate broadband wireless networks, a crucial issue must be addressed: how to support a variety of services and applications within the broadband wireless networks? As an example, there is an increasing need to efficiently support applications such as voice over IP (VoIP), video streaming, music downloading, IP TV, and many others. Apparently, the existing “access-oriented” design may not be a good answer because of the following reasons: • Efficiency: Existing design may not be able to fully exploit the potential of wireless networks because a customer always needs to connect to an access point, which is very likely a bottleneck. • Quality of service: For many existing designs developed to gain Internet access, the customer may not be able to obtain the desired quality of service (QoS) because all services are provided by the Internet, which in practice can only provide best effort service. • Incentive of the service provider: One critical issue that has been largely ignored is that the access-oriented design may not be fair to the service provider who develops the infrastructure, because the service provider can only earn the access fee, which is usually paid monthly and is relatively low compared to the deployment cost. To address the above issues, the service-oriented design on the network layer has been proposed recently and has gained increasing interest in both the research and industrial communities. With such momentum, there is an urgent need to better understand as well as keep track of cutting edge research on service-oriented broadband wireless network architecture. We expect that this special issue can help address that need, as well as help researchers looking to jump on the bandwagon. Therefore, this issue will focus on recent advances

in as well as survey articles on service-oriented broadband wireless network architecture. The response to our Call for Papers was overwhelming, with a large number of articles submitted from around the globe. During the review process, each paper was assigned to and reviewed by at least three experts in the relevant area, with a rigorous two-round review process. Due to the lack of space, we can only accommodate eight excellent articles covering various aspects of service-oriented design. The first article, “Security in Service-Oriented Vehicular Networks” by Haojin Zhu et al., discusses the security and privacy aspects of service-oriented vehicular networks, which may provide diverse commercial services, such as Internet access, real-time traffic information, video streaming, and content distribution. In the second article, “Multipath Routing for Multiple Description Video Communications over Wireless Mesh Networks,” Bo Rong et al. address the video streaming in wireless mesh networks (WMNs), which have drawn significant attention from academia and industry as a fast, easy, and inexpensive solution for broadband wireless access. The third article, “Using P2P Overlays to Provide QoS in Service-Oriented Wireless Networks” by Luca Caviglione et al., investigates a service-oriented wireless networks architecture based on a peer-to-peer overlay model, which provides the capability for distributed bandwidth management in a controlled ad hoc deployment. Xi Zhang et al. studies an emerging technology, network coding, in service-oriented wireless networks in the fourth article, “Network Coding Based Scheduling and Routing Schemes for Service-Oriented Wireless Mesh Networks.” In this article the authors envision future service-oriented wireless mesh networks delivering a large volume of traffic for diverse services via network coding in the backbone of a wireless mesh network. In the fifth article, “A Quality-Driven Decision Engine for Live Video Transmission under Service-Oriented Architecture,” Dalei Wu et al. discusses an important component of the service-oriented architecture, i.e., the decision engine, which is responsible for creating workflows for providing end-to-end QoS of a given task.

GUEST EDITORIAL The sixth article, “Dynamic Composition of Services for End-To-End Information Transport” by Carolina Fortuna et al., addresses the complexity in the design of service-oriented wireless networks. Their studies demonstrate the key advantages of service-oriented design vs. existing architectures in terms of dynamism and flexibility. In the seventh article, “Topology Control for ServiceOriented Wireless Mesh Networks,” Tao Zhang et al. investigate a fundamental issue in multihop wireless networks: topology control. Unlike most existing topology control schemes in the literature, the authors address the requirements of upper layer applications or services in their topology formation. Last but not least, Hongfei Du et al. present the eighth and last article, “Downlink Scheduling for Multimedia Multicast/Broadcast over Mobile WiMAX: Connection-Oriented Multistate Adaptation.” In this article the authors systematically investigate the design issues and state of the art in multimedia downlink scheduling in a multicast/broadcast-based WiMAX system. In closing, we would like to thank all the authors for their excellent contributions. We also would like thank all the reviewers for the time they dedicated to reviewing the papers, and for their valuable comments and suggestions for improving the quality of the articles. Finally, we appreciate the advice and support of the former and current Editorsin-Chief of IEEE Wireless Communications, Drs. Abbas Jamalipour and Yuguang Michael Fang, for their help in the publication process.
