异构无线网络共存与融合关键技术研究

Wireless network is a key technology for Internet of Things (IoT). The fast development of IoT presents three important trends, namely diversified application demands, heterogeneous network devices, and shared operational space. Those trends induce new challenges to wireless network technologies. This project focuses on key challenges and open problems in typical IoT applications, and conducts research study on coexistence and convergence of heterogeneous wireless networks. Following the logical outline from coexistence, concurrency to convergence, we try to respectively propose interference-tolerance-based coexistence mechanism, predictable concurrency space, concurrent transmission protocol over heterogeneous links, and cross-technology communication based on energy coding. Through those studies, we aim at building a generic, efficient, and reliable technological framework for coexistence and convergence of heterogeneous wireless networks. We plan to deploy application systems in scenarios like industry and energy Internet and try to achieve high-quality research results. We hope our research in this project can play an important role in the phase of standardization and industrialization of IoT.
