Wireless Sensor Network in Agriculture: Needs, Challenges and Solutions

Wireless communication technologies are increasingly growing in today’s era, which are providing great research opportunities in the networking area. Wireless sensor network (WSN) is one such example of wireless communication technology. WSNs are widely used in agricultural field in order to help farmers cut down their expenses and increase the profit margin. Precision agriculture (PA) is a management strategy that helps to improve the quality as well as the quantity of the production. In this paper, sensor networks are classified on the basis of different parameters, the various issues and the challenges that are faced while deploying WSNs are also reviewed for improved farming. In this review paper, the comparison of different wireless communication protocols and energy-efficient protocols is analyzed comprehensively.
