Cooperative and Cognitive Designs towards Resource-Efficient Wireless Communications

今天，无线技术是人类生产力和娱乐所必需的主要应用和新兴系统的核心。无线通信能力已经成为无所不在的信息访问、普适计算和社会交流的基本要求。需求的指数增长不断地给无线通信基础设施带来压力，要求其在无线电频谱、运营成本和能源消耗方面保持运营效率。由于频谱和其他网络资源有限，未来的无线设计必须进行根本性转变，转向完全协作和认知的模式，以优化资源效率实现智能通信。 尽管有这些承诺，但完全协作和认知的设计面临着重大挑战，例如分布式实施策略和认知网络动态和需求的有效网络资源管理。该研究计划旨在研究用于协作中继的分布式协作算法和认知网络资源管理策略。通过网络架构、协议和处理算法的集成视图，我们瞄准了新的统一设计，这些设计可以在物理层(PHY)、介质访问层(MAC)和网络层协同使用技术和策略，以在全面的范围内最大限度地提高合作收益。 预计这项研究计划的成果将对最先进的研究做出重大贡献，以建立我们对合作系统设计的基本理解和洞察力，为未来的无线应用和服务开发基本政策和创新的实用技术。拟议的研究对于加拿大经济的电信部门在开发创新的无线技术以加强加拿大通信基础设施的质量和能力方面至关重要。

Wireless technologies today are at the heart of major applications and emerging systems essential for human productivity and entertainment. Wireless communication capabilities have become the essential requirement for ubiquitous information access, pervasive computing, and social exchange. The exponential growth of demands continuously put pressure on the wireless communication infrastructure to be operationally efficient in radio spectrum, operating cost, and energy consumption. As spectrum and other network resources are limited, this necessitates a fundamental shift in future wireless designs toward a fully cooperative and cognitive paradigm that enables intelligent communication with optimized resource efficiency. Despite the promises, fully cooperative and cognitive design faces major challenges, such as distributed implementation strategies and effective network resource management cognitive the network dynamics and needs. The proposed research program aims to investigate into distributed cooperative algorithms and cognitive network resource managing strategies for cooperative relaying. With the integrated view of network architecture, protocols, and processing algorithms, we target novel unified designs that synergize techniques and strategies across the physical (PHY), medium access (MAC) and network-layers to maximize cooperation gain in a full-fledged scale. The outcome of this research program is expected to contribute substantially to the state-of-the-art research towards establishing our fundamental understanding and insights of cooperative system design, developing foundational policies and innovative practical technologies for future wireless applications and services. The proposed research is vital to the telecommunications sector of the Canadian economy in developing innovative wireless technologies to strengthen the quality and capacity of Canada’s communications infrastructure.
