Power consumption is a common problem in wireless sensor networks that many researchers are working on. It represents one of the most serious challenges in wireless sensor networks, as reducing node power consumption can extend the life of the network to a longer time even in the presence of external disturbances. The goal is to reduce power consumption while maintaining the required data throughput in wireless sensor networks. In this thesis, the event-based proportional integral derivative (PID) controller is designed to reduce the power consumption of a wireless sensor network system. Two types of binding are adopted for the event-based PID controller design. The first type is based on the event-based PID controller implementation of a state feedback-controlled system. As for the second type, the PID controlled system has been applied. Initially, the parameters of all controllers were determined by a trial and error approach. Then, in order to improve the performance of the controlled system, the Gray Wolf Optimization (GWO) algorithm was applied to improve the selected control parameters depending on the appropriate performance function. The discussion was attended by the Assistant Head of the Department for Scientific Affairs and Graduate Studies in the department (Prof. Dr. Muhammad Youssef Hassan). On this occasion, we congratulate the student (Najat Muslim Ramadan) and wish her continued success.
