【主讲人简介】

 李永会教授于2002年11月获博士学位并于2003年加入悉尼大学卓越通信研究中心。他现在担任悉尼大学电子信息学院教授以及无线工程实验室主任。由于他本人的杰出贡献，他在2008年获得澳大利亚伊丽莎白女皇研究员专项基金。该基金每年澳大利亚只有50人被资助，成功率低于10%。并于2012年再次获得澳大利亚未来院士专项基金资助。该基金在2012年通讯领域只有他一人获得。由于在协作通信方面的突出贡献，李教授于2017年当选电子电气工程师协会会士。

Yonghui Li received his PhD degree in November 2002. Since 2003, he has been with the Centre of Excellence in Telecommunications, the University of Sydney, Australia. Li is now a Professor and Director of Wireless Engineering Laboratory in School of Electrical and Information Engineering, University of Sydney. He is the recipient of the Australian Queen Elizabeth II Fellowship in 2008 and the Australian Future Fellowship in 2012. He is an IEEE Fellow for contributions to cooperative communications technologies.

【内容简介】

将智能设备、平台和环境结合起来已成为了目前学术和工业界的重要技术研究方向，它可以实现重大的社会变革和经济增长。将整个物理世界通过互联网连接起来，也即物联网，通过物体和环境间的自由交互和处理，成为了电力，交通，工业控制，公用事业管理，医疗保健，水资源管理和采矿等领域的固有组成部分。无线网络是物联网的关键使能技术之一，其灵活性，可扩展性和成本低廉的特点使得它可普遍用于最后一公里连接。物联网网络的属性和流量模型与传统通信系统的属性和流量模型本质上不同，传统通信系统旨在传输语音，数据和多媒体。而物联网面临着现有网络协议无法解决的许多独特挑战，包括巨大数量的设备，在有限带宽的大规模网络中传输大量突发数据，以及适应各种流量模式和服务质量（QoS）要求的能力。一些物联网应用具有严格的延迟和可靠性要求，这是现有无线网络所无法满足的。应对这些挑战需要开发新的无线接入技术，底层网络协议，信号处理技术和安全协议。在本次演讲中，我将介绍物联网网络开发，架构，关键挑战，要求，潜在解决方案以及该领域最近的研究进展，特别是在5G大规模接入和高可靠低延时通信中。

Connected smart objects, platforms and environments have been identified as the next big technology development, enabling significant society changes and economic growth. The entire physical world will be connected to the Internet, referred to as Internet of Things (IoT). The intelligent IoT network for automatic interaction and processing between objects and environments will become an inherent part of areas such as electricity, transportation, industrial control, utilities management, healthcare, water resources management and mining. Wireless networks are one of the key enabling technologies of the IoT. They are likely to be universally used for last mile connectivity due to their flexibility, scalability and cost effectiveness. The attributes and traffic models of IoT networks are essentially different from those of conventional communication systems, which are designed to transmit voice, data and multimedia. IoT access networks face many unique challenges that cannot be addressed by existing network protocols; these include support for a truly massive number of devices, the transmission of huge volumes of data burst in large-scale networks over limited bandwidth, and the ability to accommodate diverse traffic patterns and quality of service (QoS) requirements. Some IoT applications have much stringent latency and reliability requirements which cannot be accommodated by existing wireless networks.  Addressing these challenges requires the development of new wireless access technologies, underlying network protocols, signal processing techniques and security protocols. In this talk, I will present the IoT network development, architecture, key challenges, requirements, potential solutions and recent research progress in this area, particularly in 5G massive connectivity and uRLLC.
