Design and implementation of a Simulator for performance evaluation of WSN using vacation policies

Abstract

Sensor networks are widely used for various applications but are constrained by limited energy resources, which necessitates the development of energy-efficient network designs. The use of vacation policies is a promising approach for reducing energy consumption while maintaining network performance. This project presents the design and implementation of a simulator for the performance evaluation of sensor nodes using vacation policies for energy saving. The proposed simulator is designed using discrete-event simulation techniques. The simulation model allows us to investigate the impact of various parameters such as arrival rates, service times, and threshold values used in vacation policies. The simulator also enables the comparison of different vacation policies and provides insights into the trade-off between energy conservation and system performance. The report describes the underlying system dynamics, and the methods used for data collection and analysis, and provides examples of simulation studies to illustrate the usefulness of the simulator in evaluating the performance of a sensor node and guiding the design of energy-efficient sensor network systems. Based on our analysis we demonstrate the interplay between arrival rate, buffer size, and service policies in determining system performance. By considering these factors and their trade-offs, it is possible to optimize queuing systems to achieve desired outcomes and improve overall efficiency.
