当今的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处不在的信息访问、普适计算和社会交换的基本要求。需求的指数增长持续地对无线通信基础设施施加压力，以在无线电频谱、操作成本和能量消耗方面操作高效。由于频谱和其他网络资源是有限的，这就需要在未来的无线设计中向完全协作和认知范式进行根本转变，从而实现具有优化资源效率的智能通信。 尽管有这样的承诺，完全合作和认知设计面临着重大挑战，如分布式实现策略和有效的网络资源管理认知网络的动态和需求。本研究计画主要针对分布式合作中继演算法与认知网路资源管理策略进行研究。通过对网络架构、协议和处理算法的综合考虑，我们的目标是新颖的统一设计，这些设计将物理层（PHY）、介质访问层（MAC）和网络层的技术和策略协同起来，以最大限度地提高全面合作的收益。 这项研究计划的成果预计将大大有助于国家的最先进的研究，建立我们的基本理解和合作系统设计的见解，发展基础政策和创新的实用技术，为未来的无线应用和服务。拟议的研究对加拿大经济的电信部门至关重要，有助于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。

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.
