Analyzing Wireless Network Implementation Using Cooja Simulation in Contiki Operating System

Abstract

This research aims to analyze the performance of different wireless network topologies using the Cooja simulator within the Contiki operating system environment. Four network topologies—chain, ring, tree, and mesh—were simulated to evaluate their energy consumption, hop count, and radio duty cycle (RDC) performance. The results indicate that the mesh topology balances energy efficiency and performance, making it suitable for Internet of Things (IoT) and wireless sensor network (WSN) applications. In contrast, the chain topology exhibited higher energy consumption and increased hop count, highlighting the importance of choosing an appropriate topology to ensure network efficiency and quality of service (QoS).
