Performance Evaluation of Star Topology IoT Network

This document is a technical report that details the performance evaluation of a star topology IoT network using IEEE 802.15.4 devices. It outlines an experiment where multiple IoT devices are connected to a single sink, simulating a scenario typical in large campuses. The report describes the setup of the experiment, including the configuration of the network and the parameters for the simulations conducted using NetSim. It explains the process of saturation throughput analysis, where the performance of the network is assessed under heavy loading conditions. The report also compares simulation results with mathematical analyses to provide insights into network performance. Additionally, it discusses the aggregate throughput achieved with varying numbers of nodes and the impact of contention on throughput. The findings are supported by data presented in tables and figures, illustrating the relationship between the number of nodes and the aggregate throughput in packets per second.
