Introduction With the recent technological advancements in smaller sensor devices with ubiquitous sensing and monitoring capabilities, Wireless Sensor Networks (WSN) are evolving as one of the most significant technologies of 21st century (Ruiz-Garcia, Lunadei, Barreiro, & Robla, 2009). Though wired networks provide more stable and reliable communication, wireless networking does provide more advantages with connectivity without being tethered. WSN with dense wireless networks of small, low cost sensors for collecting and disseminating environment data has facilitated connecting, monitoring and controlling of physical environments and environmental conditions such as temperature, humidity, pressure from remote locations with better accuracy which are not possible with wired networks (Potnis & Rajeshwari, 2015). Moreover, with the unique characteristics of flexibility, energy efficiency, distributed intelligence, low cost and most importantly with very good sensing and monitoring capabilities, WSNs are serving wide range of applications in various fields including remote environmental monitoring, home security, industry applications, military purposes such as target tracking by preparing and providing a ubiquitous computing environment (Ruiz-Garcia et al., 2009). In this paper, I will mainly focus on analyzing and evaluating the current Wireless Sensor Networks (WSN). This paper starts with an overview on fundamentals of WSNs, by providing necessary background to understand
