异构物联网高效融合理论与关键技术研究

With the boom in Internet-of-Things (IoT) devices and versatile protocols, it has become a common scenario where a diversity of IoT devices share the same spectrum resources. The integration of heterogeneous IoT can effectively overcome the hurdles of low energy and spectrum efficiency induced by the coexistence of heterogeneous IoT devices, and thus has drawn wide attention. This project studies the theory and key technologies for high-efficient integration of heterogeneous IoT, and aim at resolving the conflict between the resource limitation in IoT devices and competition cost induced by heterogeneous links. The main innovations are as follows. For the intense competition cost problem in heterogeneous IoT, this project studies the communication approach that employs side channel information, provides an in-depth analysis of the side-channel communication mechanism for heterogeneous systems and designs a frequency-shift-based cross-technology communication mechanism to improve spectrum efficiency without compromising traditional protocols.

随着物联网设备数量和协议种类的不断增加，多种物联网设备共享相同频谱资源的情况日益普遍。异构物联网融合可以有效解决异构设备共存所带来的低能谱效率等问题，最近受到广泛关注。本项目研究异构物联网高效融合理论与关键技术，致力于解决物联网终端资源受限与异构链路竞争开销之间的矛盾，主要创新点如下：针对物联网中异构节点高竞争开销问题，研究使用边信道信息进行通信的合理方法，深入分析面向异构制式的边信道通信机制，设计使用频谱偏移作为通用的跨技术通信机制，实现高谱效且不影响传统协议的异构网络通信协议。
