Wireless Sensor Network (WSN) represents a key network in the present and future Internet of Things (IoT) technology. WSN has an uncountable number of applications and is commonly used to aggregate information and control the physical environment remotely through small embedded devices known as wireless sensor nodes. Power consumption is one of the main challenges in WSN due to the limitation of power resources. Consequently, several techniques have been followed to optimize power consumption. The feedback control system is one of the routes that has been utilized to minimize power consumption in WSN using the mathematical model of power and rate control in WSN. In this paper, a concise review of various types of control systems that are deployed for power saving in WSN will be discussed. The comparison between the applied control strategies is the key finding.
