LTE-advanced machine type communication for Internet of Things

机器对机器(M2M)或机器类型通信(MTC)作为物联网(IoT)实际实现的使能技术，是一种绕过基站在设备之间建立无所不在的直接连接链路的新兴技术。下一代蜂窝网络称为第五代(5G)长期演进高级(LTE-A)，被认为是实施M2M通信的现成基础设施。然而，M2M-LTE应用带来的主要技术挑战包括不同的数据事务、多样化的应用和大量的连接，为了适应如此庞大的设备数量，M2M系统架构应该提供 具有超低复杂度、极高能效、关键时序、可靠性和覆盖面广等优势。 由于无线介质的开放性和M2M网络体系结构涉及广播和叠加的特殊性，无线M2M通信经常容易被未经授权的用户窃听，因此确保无线信道上的安全传输免受安全攻击是网络设计中的一大挑战。 在与我们的支持组织WiMatek Systems协商后，我们确定了5G LTE网络中M2M通信的一个关键问题，即M2M通信的物理层安全。其目标是设计创新的保密算法，在M2M通信中能够在较短的持续时间内工作，并可在实践中实现。在这个项目中，我们建议开发新的理论、算法和设计指南来解决这些研究挑战，并将使M2M通信的实际实施成为可能。

Machine-to-machine (M2M) or machine-type communications (MTC),which acts as an enabling technology for the practical realization of Internet-of-Things (IoT), is an emerging technology to establish ubiquitous direct connectivity links among devices and bypassing the base-station. The next generation of cellular networks, called the fifth generation (5G) Long-Term Evolution-Advanced (LTE-A), are considered a ready-to-use infrastructure to implement M2M communications. However, the major technical challenges posed by M2M-LTE applications include different data transactions, diverse applications, and a large number of connections.To accommodate such a massive number of devices, M2M system architecture should offer advantages such as ultra-low complexity, extreme energy efficiency, critical timing, reliability and wide coverage. Due to the open nature of the wireless medium and the specific nature of the M2M networking architecture, which involves broadcast and superposition, wireless M2M communication is often vulnerable to eavesdropping by unauthorized users and, thus, guaranteeing secure transmission over the wireless channels against security attacks discomposes great challenges in network design. In consultation with our supporting organization, WiMatek Systems, we have identified a key issue of M2M communications in 5G LTE networks, which is the physical layer security in M2M communications. The target is to to design innovative secrecy algorithms that can work in short durations in M2M communications and can be implemented in practice. In this project, we propose to develop new theories, algorithms and design guidelines that address these research challenges and will enable the practical implementation of M2M communications.
