   ABSTRACT     = {Internet of Things (IoT) is defined as the connection 
      between places and physical objects (i.e., things) over the Internet 
      via smart computing devices. It is a rapidly emerging paradigm that 
      encompasses almost every aspect of our modern life, such as smart 
      home, cars, and so on. With interest in IoT growing, we observe that 
      the IoT discussions are becoming prevalent in online developer 
      forums, such as Stack Overflow (SO). An understanding of such 
      discussions can offer insights into the prevalence, popularity, and 
      difficulty of various IoT topics. For this paper, we download a large 
      number of SO posts that contain discussions about various IoT 
      technologies. We apply topic modeling on the textual contents of the 
      posts. We label the topics and categorize the topics into 
      hierarchies. We analyze the popularity and difficulty of the topics. 
      Our study offers several findings. First, IoT developers discuss a 
      range of topics in SO related to Hardware, Software, Network, and 
      Tutorials. Second, secure messaging using IoT devices from the 
      Network category is the most prevalent topic, followed by scheduling 
      of IoT script in the Software category. Third, all the topic 
      categories are evolving rapidly in SO, i.e., new questions are being 
      added more and more in SO about IoT tools and techniques. Fourth, the 
      ``How type of questions are asked more across the three topic 
      categories (Software, Network, and Hardware), although a large number 
      of questions are also of the ``What'' type: IoT developers are using 
      SO not only to discuss how to address a problem related to IoT, but 
      also to learn what the different IoT techniques and tools offer. 
      Fifth, topics related to data parsing and micro-controller 
      configuration are the most popular. Sixth, topics related to 
      multimedia streaming and Bluetooth are the most difficult. Our study 
      findings have implications for all four different IoT stakeholders: 
      tool builders, developers, educators, and researchers. For example, 
      IoT developers and newcomers can use our findings on topic popularity 
      to learn about popular IoT techniques. Educators and researchers can 
      make more tutorials or develop new techniques to make difficult IoT 
      topics easier. IoT tool builders can look at our identified topics 
      and categories to learn about IoT developers' preferences, which then 
      can help them develop new tools or enhance their current offerings.}
