Wireless sensor networks (WSNs) are being used in a wide variety of critical applications such as military and healthcare applications, agriculture, and industrial process monitoring. WSN has several advantages including easy installation, cost-effectiveness, small size, and low power consumption. In recent years, the demand for environmental monitoring and remote control in agriculture has been rapidly growing. Typically, sensors in the agriculture fields will gather, soil, weather, crop, water level, and moisture level for soil fertility detection, fire detection, irrigation detection, and flood detection in the future and to take action robustly to increase and safeguard the crop productivity.
