# Internet of Things: A Scientometric Review
## 3 Country and Author Research Analysis
### Country Analysis  
A list of the countries with the most associated publications was generated. Figure 2 shows the top seven countries, along with the percentage of documents published per year. In 2002, one article was published on Forbes by [PERSON]; unfortunately, the database does not associate any author address for this document and the sample had to be removed from this data set according to methodology. In 2003, two conference papers were published by United States authors [19; 20]. In 2004, there was one review publication in the United States [21] and one article in the United Kingdom [22]. Figure 1: Documents per year published (WoS and Scopus) with the search string “Internet of Things” (IoT) for the period 2000 to 2016. (**a**) before the duplicates-removal filter; (**b**) after duplicates-removal filter. Germany [23] and Malaysia [24] first appear in 2005, joined by the United States [25]. These three conference papers demonstrated how the RFID can boost Internet of Things for manufacturing, packing, tracking, and automobile logistics. In 2006, the total publications grew from 3 to 12, with more countries participating, such as France [26; 27], Switzerland [28; 29], and Japan [30]. From 2006 to 2009, Germany led the number of publications with 2, 3, 9, and 11, respectively. During that period, the German author [PERSON] led the citations count with a proposed framework for integrating web services and mobile interaction with physical objects [31]. China drastically increased from 11 to 239 publications from 2009 to 2010, continuing to contribute more than half of the globally published documents between 2010 to 2013. Most of that growth resulted from China's Twelfth 5 Year Plan (2011-2015), which included the development of the Internet of Things [32]. The conference paper \"IOT Gateway: Bridging Wireless Sensor Networks into Internet of Things\" by [PERSON] was the most cited IoT paper during this period for China, as it explained how an IoT Gateway could make a bridge between wireless sensors networks and traditional communications networks to the Internet [33]. From 2014 to 2016, China maintained the highest rank, contributing 20% of the globally published documents, as well as a peak in 2016 and h-index of 47. In 2014, the United States was second to China with 187 publications and h-index of 42. India's contributions grew at a rate of 153%, 103%, 286%, and 120%, in 2013 to 2016, respectively, moving from the 8 th to 3 rd position in 2013 and 2016, respectively. The Indian daily \"The Economic Times\" forecasted the country is expected to see a rapid 31-fold growth of IoT devices to reach 1.9 billion by 2020 [34]. Expanding the results from Figure 2, Table 3 shows the top 50 countries of the primary author with the average percentage growth and the h-index of each country from the last three years (2014 to 2016). Of the top 10 countries, South Korea represents the maximum average growth with 206%, where the mobile carrier SK Telecom (Seoul, South Korea) launched the first commercial low-cost Internet of Things (IoT) network in 2016 [35]. However, this growth is not reflected yet (next year) in the available literature and thus the data set has an h-index of 16, only half of its successor in this list, Italy. In the same way, this list includes the top growing countries with low h-index but anticipated to be higher next year: Indonesia, Turkey, Russian Federation, and Pakistan. Figure 2: Internet of Things percentage of documents published per year by the top 7 first author’s corresponding address country for the period 2002 to 2016. The International Data Corporation (IDC) predicts that, by 2019, 20% of local and regional governments in Indonesia will use the Internet of Things to turn infrastructure such as roads, street lights, and traffic signals into assets instead of liabilities [36]. In addition, the Dutch IoT
