城市范围骑手室内状态自动检测系统

      大规模场景中手机设备和环境多样性使传统室内状态检测方法性能下降，两种异构性对于感知数据的影响模式难以获取，需通过历史交互感知数据学习。通过深入分析学习不同手机设备和环境之间对于感知数据影响模式的相关性，并利用此相关性设计为新领域预测有效状态检测模型方案，提升大规模室内状态检测系统性能。

蜂窝网络信号地图构建

       众包感知信号分布稀疏不均匀，且因外部环境等影响因素造成信号值波动频繁，丞需设计合理方案构建精准信号地图。通过深入分析基站间、基站内以及时间维度上的信号特征，利用贝叶斯张量分解方法设计相应的信号恢复方案，从而构建细粒度信号地图。

基于多源数据融合的城市人流检测

      现有基于单源数据的城市人流检测工作只能片面地理解城市人流情况，难以从全局的角度理解城市人流的全貌。通过深入分析多源异质物联网系统数据，根据异构数据的关联信息，设计基于上下文信息的多视图学习方案，实现城市人流检测的关联优化。

边缘计算环境下目标车辆实时检测技术设计与实现

       边缘计算场景下，目标车辆检测任务实时性要求高，而边缘计算平台资源有限计算耗时长，道路环境动态变化。该研究提出Multi-granularity的车辆检测算法，根据实时路况做自适应决策，保证在边缘有限计算资源下实时定位目标车辆。

共享合同停车系统

       为了缓解停车难并充分利用城市停车资源，采用合同停车共享服务达到双赢的局面。借助物联网技术，大多数现代停车场都记录了车辆的细粒度停车数据。基于这些数据，设计一个共享合同停车系统，利用空闲停车位的可靠时期预测停车时间，向驾驶员分配空闲停车位。相关论文发表在人机交互与普适计算领域知名会议ACM International Conference on Ubiquitous Computing。

       围绕“智慧物联网”为主题，基于BLE5.1协议中新发布的AoA寻向方法，结合计算机视觉技术，实现一种可视化的物联网设备交互方式。

异构设备间泛在直联技术

       异构设备共存场景下，设备间干扰愈发严重，这使得异质物联网建立信息可靠交互、设备统筹组织的需求越来越迫切。基于泛在直联通信技术，研究异构设备间的RTS/CTS机制，实现异构设备间的信道协调使用，有效避免异构设备间干扰，提高频谱资源的利用率。

低信噪比低功耗广域网抗干扰通信系统

      工作在ISM频段的新型低功耗广域网协议易受到同频高功率信号干扰，低信噪比工作场景使得错误信号难以恢复，亟需物理层设计对底层符号实现干扰下的有效复原。研究基于短时傅里叶变换的广域网抗干扰系统方案，利用多种信号处理方法来提取LoRa信号时频特征可以检测多种、高流量同频干扰并从物理层进行复原。

物联网底层并发通信技术

       考虑物联网底层网络中的并发传输时的各项实际因素，提出一种新颖的利用多维度信息的物理层方法来解码冲突传输，通过整合频率和功率特征信息来分离重叠信号中的符号。相关论文发表在国际计算机网络领域权威会议 IEEE International Conference on Network Protocols。
