Recent trend in wireless sensor network and its applications: a survey

Purpose - This paper aims to review existing wireless sensor network (WSN) setups in various domains, focusing on affordable WSN so that it can be effectively utilised in solving the environmental problems. WSN is being explored in many applications such as home security, smart spaces, environmental monitoring, battlefield surveillance and target tracking. WSN consists of a number of tiny, low-powered, energy-constrained sensor nodes with sensing, data processing and wireless communication components. Creating a WSN setup will make the monitoring system effective and in future, it will give a roadmap for solving some common societal problems. Design/methodology/approach - Various research papers in the area of WSN have been reviewed on the basis of technologies and application on different fields. Findings - WSN was found to be the most effective solution in areas which are less explored due their hazardous nature and are difficult to reach. Originality/value - This review is based on research papers available and a recent trend in the area of WSN has been explored.
