With the aim to promote the amalgamation between military engineering and command systems or weapon platforms, this paper introduces the ideas and technologies of internet of things (IoT) into the research area of military engineering, proposes the research concept: IoT of military engineering (MEIoT). In the paper, the basic concept of MEIoT is defined, and the conceptual model of it is also established. On the basis of discussing the technology challenges of MEIoT, this paper presents several research advances and fruits of the authors on the military-engineering-sensing technologies, network transportation technologies in special spaces of military engineering, the data mining and managing technologies for multi-mode data in military engineering, and software paradigm of MEIoT. Finally, an example of MEIoT applied in naval ports is provided. The research of MEIoT will be of great significance to enhance the integrated supporting and protective ability of military engineering.
