## 1 Introduction  
The Internet of Things (IoT) is described and discussed in the lecture notes by [PERSON] _et al._[1]. The authors conclude that the IoT can be very diverse, depending partly on the sub-technologies applied. The current work supports this way of thinking as mentioned in the abstract. The research focused on smart buildings in the context of smart cities with smart energy, smart transport, _etc._ Figure 1 illustrates the connections between various applications in this and other work by the author, including smart buildings and smart cities with a focus on energy.  
Like system control, the IoT could be split into the communication part (the Internet), the sensing part (the Sensing Internet), and the controlling part (Remote Controlling). In this way, the Sensing Internet denotes the enormous potential of the IoT, increasing the common understanding of it. On the other hand, understanding the IoT as a \"service\" [2] suggests the meshing of sensed data with all other kinds of Internet-related components.  
The use of sensors within the IoT combined with the concept of Big Data [3] seems to be an important aspect of current research efforts. [PERSON] _et al._[4] propose a solution to the challenge of finding, retrieving and utilizing sensor streams in a stable manner. [PERSON] _et al._[5] propose a whole open platform for designing a sensing IoT based on wireless sensor networks (WSNs), as applied in the current research. It should be noted that [PERSON] _et al._[6] have presented an alternative approach based on the internet standards.  
WSNs are now widely used due to their flexibility, adaptability and potential simplicity. Simplicity is only possible for very well-designed setups, and it demands quite a lot of work, because of the great flexibility of the technology and its lack of maturity. But keeping things simple is seen as a necessity in this paper.  
A previous paper described WSN technology and proposed its application in the building sector as an alternative to Radio Frequency Identification--RFID technology [7]. The introduction of WSN technology was aimed at improving the overall performance and quality of the sector. On basis of an analysis of the commercial hardware available, it was concluded that wireless sensor technology has not yet developed to its full potential with respect to applications in the building sector. Other studies dealing with this topic have been mostly theoretical (based on computer simulations, e.g., [8, 9]) or pilot studies without full scale implementation of the technology (e.g., [10, 11, 12, 13]). Current research is changing this situation rapidly, as the following examples show: an anti-collision solution for crane groups based on WSN and IoT technology [14]; a logistics solution that could be applied on building sites [15]; and an application for the management of fire emergencies [16]. However, these are proposals based on research and not yet commercial solutions.  
Although the building sector is rather reluctant to introduce extensive new technologies in the proposed way, the basic infrastructures are already in place to receive them in a country like Denmark.

The Internet is everywhere, and skilled personnel are available with competence in installation, for measurement and on the software side. Planning WSN introduction in Greenland brought up some new considerations with respect to all these issues. The current paper provides some observations and a discussion on the degree to which the Sensing Internet, represented by WSN technology (bearing in mind that these are not the same thing) can be robust in rural areas.
