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

在接下来的几年中，预计用户将期望无线网络提供与今天的有线网络类似的性能。因此，未来无处不在的无线网络将需要提供比现在更高的可靠性、更高的可访问性、更大的带宽以及对更广泛应用的更多支持。为了解决这些问题，提高无线链路的可靠性和吞吐量，近年来发展了一些物理层传输技术，如协作通信和具有动态可重构辐射模式的天线。我们可以预计，上述技术将在10到15年内实现商业化部署。本研究计划中考虑的传输技术引入了新的范例，例如多个节点合作建立一条通信链路或具有时变覆盖或干扰区的节点。因此，在共享无线介质中和用户之间产生了复杂的交互。因此，研究无线系统中有效集成协作和可重构天线是非常重要的。该研究项目通过探索新的利基来开发突破性的方法，特别是针对多址访问控制层、无线电链路控制层以及这些系统的实现和表征，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乏，要么处于初级阶段。我们的研究项目将处于这个不断增长的活动领域的最前沿，因此将对社区产生重大影响。它们也有可能影响整合合作通信和动态辐射模式多样性的未来无线网络的标准化进程，并可产生知识产权，通过技术转让将其转化为当地工业的经济活动。最后，该项目将有助于培养对无线通信系统有深入理论和实践理解的高素质人才，这将在提高加拿大无线行业的竞争力方面发挥作用。

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.
