Management techniques and architectures in heterogeneous wireless networks

未来的无线和移动网络将依赖多种无线电接入技术，包括蜂窝网络、无线局域网，例如IEEE 802.11 WIFI(无线保真度)，个人区域网络，例如蓝牙，以及多跳/自组织可变拓扑网络。跨越这种接入异构性的无缝系统间移动性将是下一代(标记为第四代(4G))无线网络的主要特征。技术格局的这种变化进一步挑战了今天的无线电系统，因为容量需求服务的数量不断增加，从传统的对话音频到对话视频、语音消息、流音频和语音、互动游戏、网络浏览、文件传输和电子邮件。如果要维持服务质量(Qos)，没有一个单一的无线电系统能够有效地提供多服务递送。这给网络研究人员在提供商和用户端都带来了严重的问题。最近的兴趣是使不同但互补的无线电系统相互配合，共同提供无与伦比的服务交付水平。本研究的目的是区分并设计出适用于4G无线网络的有效资源管理技术和架构。另一个内在目标是实现强调考虑移动终端有限能力的设计方法，包括电池寿命和处理能力。此外，我们还将提出跨此类平台的端到端服务质量体系结构，并评估服务质量服务交付的替代技术或方法。这一领域的研究将根据用户概况和要传输的数据类型，通过最高效/首选的网络提供个性化服务。该项目的研究成果代表着朝着满足“随时随地、任何形式”的传播理念迈出了明确的一步。更重要的是，这些发现将使加拿大电信业和企业受益，使他们能够以既省时又省钱的方式规划、实施和部署各种无线网络。

Future wireless and mobile networks will rely on multiple radio access technologies, including cellular networks, Wireless LANs (WLAN), e.g. IEEE 802.11 WiFi (Wireless Fidelity), personal area networks, e.g. Bluetooth, and multi-hop/ad hoc variable topology networks. Seamless intersystem mobility across such access heterogeneity will be the capital feature in next generation, labelled Fourth Generation (4G), wireless networks. This change in the technological landscape further challenges today's radio systems by the increasing amount of capacity-demanding services, which span from traditional conversational audio to conversational video, voice messaging, streamed audio and voice, interactive gaming, Web browsing, file transfer, and emailing. No single radio system can effectively provide multi-service delivery if Quality of Service (QoS) is to be maintained. This poses serious issues to networking researchers on both the provider and the user side. Recent interest has been in interworking the different but complementary radio systems that together can provide an unparalleled level of service delivery. The objective of this research is to distinguish and devised effective resource management techniques and architectures for 4G wireless networks. A further inherent objective is to realize design methodologies that emphasize mindful considerations of the mobile terminal's limited capabilities, including battery lifetime and processing power. Moreover, we will propose architectures for end-to-end QoS across such platforms and evaluate alternative technological or methodological approaches for QoS service delivery. Research in this area will offer personalized service delivery over the most efficient/preferred network, depending on the user profile and the type of data to transmit. The research findings of this project represent a definite step towards meeting the "anywhere, anytime and any form" communication concept. More importantly, the findings will benefit the Canadian telecommunications industry and business with means to plan, implement and deploy heterogeneous wireless networks in a manner that is both time- and cost-efficient.
