摘　　要：物联网数据聚合是解决物联网感知节点能量有限、计算能力有限、数据海量冗余、网络复杂异构、易于遭受攻击破坏等问题的必然选择。对ITU的物联网体系架构进行精简,构建与之适应的物联网数据聚合体系架构,以便为具体的物联网数据聚合应用系统设计提供指导。围绕该体系架构,分析物联网数据聚合技术面临的三个主要挑战:物联网数据聚合的不确定性问题,大数据聚合问题,数据聚合安全问题。并分别对各自的现有技术进行了总结和评述。Data aggregation is an inevitable choice to solve the challenges in Internet of Things( Io T) such as the limited energy of sensing nodes,limited computing power,mass data and data redundancy,complex and heterogeneous networks,and to be prone to attacking damages,etc. We simplified the architecture of the Io T proposed by ITU and constructed the adapted data aggregation architecture of Io T,so as to provide the guidance for the specific design of Io T data aggregation application system. Based on the proposed architecture,we analysed three major challenges encountered by the data aggregation of Io T: its uncertainty,the aggregation of big data,and its security. Separately,we gave the summarisation and review on the existing techniques each.
