A Deep Analysis of Applications and Challenges of Wireless Sensor Network

Wireless sensor network refer to a community of a spatially dispersed and allocated sensors to track, record the enviromental physical conditions and to coordinate the collected information at a central point. WSN are becoming increasingly important with their wide range of business applications. WSN are being used in multiple fields such as health care, agriculture, systematic observation and condition based serviliance. WSN contain multiple sensors and because of features of implementing nodes, protection and authenticity, wireless sensor network become more complex. Security has drawn much attention in WSN in the last few years. But the transmission work done by sensors, is typically critical because there are large ammount of data and sensor devices are limited. Due to small number of sensers, the system is vulnerable to multiple attacks. The basic goal of this paper is to highlight the areas where the WSN is being used and multiple challenges to wireless sensor network. The multiple attacks and challenges to WSN are mentioned in this study. This research shows that although there are many challenges to WSN but still the use of wireless sensor network in multiple field such as agricultural and healthcare helps a lot to improve the efficiency, quality and performance of the those areas.
