Design of future reliable ubiquitous networks based on cooperative networks and dynamic radiation pattern systems

在接下来的几年里，预计用户将期望无线网络提供类似于今天的有线网络的性能。因此，未来的无处不在的无线网络将需要提供比今天更可靠、更高的可访问性、更大的带宽和对各种应用的更多支持。为了解决这些问题，提高无线链路的可靠性和吞吐量，近年来发展了几种物理层传输技术，如协作通信和具有动态可重构辐射方向图的天线。我们可以预期，上述技术将在10到15年内实现商业化部署。本研究方案中考虑的传输技术引入了新的范例，例如让多个节点协作来建立一条通信链路，或者具有时变的覆盖或干扰区域的节点。因此，在共享无线介质中以及在用户之间诱导复杂的交互。因此，研究如何在无线系统中有效地集成协作天线和可重构天线是非常重要的。这项研究项目通过探索新的利基市场来开发开创性的方法，特别是多路接入控制层、无线电链路控制层以及这些系统的实施和特性，从而为这一努力做出了贡献。目前在这些领域的研究活动要么缺席，要么处于初级阶段。在这个不断增长的活动领域，我们的研究项目将走在前列，因此将对社会产生重大影响。它们还有可能影响未来无线网络的标准化进程，整合合作通信和动态辐射模式多样性，并可以产生知识产权，这些知识产权可以通过技术转让转化为当地行业的经济活动。最后，该项目将有助于培养高素质的人才，对无线通信系统有深入的理论和实践了解，这将对提高加拿大无线产业的竞争力起到作用。

In the following years, it is anticipated that users will expect wireless networks to provide a performance similar to today's wired networks. Future ubiquitous wireless networks will therefore need to offer more reliability, higher accessibility, larger bandwidth and more support to a wide array of applications than they are today. Several physical layer transmission technologies such as cooperative communications and antennas with dynamically reconfigurable radiation patterns have been developed in recent years to address these issues and improve the reliability and throughput of wireless links. We can expect that the aforementioned technologies will be commercially deployed in 10 to 15 years. The transmission technologies considered in this research program introduce new paradigms such as having multiple nodes cooperating for establishing one communication link or nodes with time-varying coverage or interference zones. Complex interactions are therefore induced in the shared wireless medium and between users. Research aimed at efficiently integrating cooperation and reconfigurable antennas in wireless systems is thus extremely important. This research project contributes to this effort by exploring new niches to develop groundbreaking approaches, particularly for the multiple access control layer, the radio link control layer, and the implementation and characterization of these systems. The current research activities in these areas are either absent or at the infancy stages. Our research projects will be at the forefront in this constantly growing sphere of activities and will therefore have a significant impact on the community. They also have the potential to influence the standardization process of future wireless networks integrating cooperative communications and dynamic radiation pattern diversity, and can generate intellectual property, which can translate into economic activities in the local industry through technology transfers. Finally, this project will contribute to the training of highly qualified personnel, with an in-depth theoretical and practical understanding of wireless communication systems, which will play a role in improving the competitiveness of the Canadian wireless industry.
