Abstract Wireless sensor networks (WSNs) have emerged as one of the huge research areas in this digital world since last few years. In this paper, we review total of 150 research papers from January 2015 to December 2015 in order to enlighten the researchers and educators about baseline of the current trends in the field. This study is a graphical and systematic review of various research works carried out in WSNs. These findings show that the research in WSNs received more attention over the past few years. For the primary research method of studying, highly cited research papers from top-rated publishers were included. Although a vast number of research objectives have been floated in this field, we analyzed that there are two main topics which are trending in 2015 as discussed in the paper. This analysis would provide insights for researchers, students, publishers, and experts to study current research trends in WSNs. Keywords Wireless sensor networks

1 Introduction Wireless sensor networks (WSNs), sometimes called wireless sensor and actuator networks (WSANs), are wireless network consisting of different devices using sensors to monitor conditions such as area, health care, environmental, air pollution, water quality, industrial, and structural health monitoring [1]. Trend analysis is an aspect of technical analysis to predict movement of particular research area in future based on past data. Since WSNs are a vast field, our objective behind this trend analysis is to find in which particular field ‘what’ and ‘how much’ of work has been done. In this paper, we propose a trend analysis on WSNs showing the current trend of year 2015. We have gone through 150 research papers of different well-known journals and reputed publishers. During trend analysis, we found that recent improvement of WSNs results in new technology and new generation of equipment that added new applications making it more accurate [2]. Observation of research papers leads us to energy and security. Energy in WSNs considered as a most important resource, because it determines life time of sensor node [3]. Most of the work during year 2015 has been done in improving energy consumption and security of WSNs. Talking about security, improving security will increase accuracy, prevent data loss, and improve privacy; researchers studied that the security in wireless sensor networks is tremendously p
