This course introduces students to the concepts, architectures, protocols, and applications of Mobile Ad Hoc Networks (MANETs) and Wireless Sensor Networks (WSNs), which form the foundation of many modern wireless communication systems and Internet of Things (IoT) applications. Unlike conventional wireless networks that rely on fixed infrastructure, MANETs and WSNs operate in dynamic and self-organizing environments, requiring efficient communication, routing, and resource management techniques.
The course begins with an in-depth study of the architecture and characteristics of Mobile Ad Hoc Networks, including node mobility, network topology, communication models, and deployment scenarios. Students will also explore the architecture of Wireless Sensor Networks, focusing on sensor node design, network organization, energy constraints, and data collection mechanisms.
A significant portion of the course is dedicated to Medium Access Control (MAC) protocols used in ad hoc networks. Students will examine how MAC protocols coordinate channel access, manage collisions, and improve network performance in shared wireless environments. The course further introduces routing protocols employed in MANETs and WSNs, explaining their fundamental operating principles, route discovery mechanisms, maintenance procedures, and performance considerations.
Students will observe and analyze the behavior of various routing protocols under different network conditions and learn to categorize them based on routing strategies such as proactive, reactive, hybrid, hierarchical, and data-centric approaches. By the end of the course, learners will possess a strong understanding of the architectures, MAC protocols, and routing mechanisms of MANETs and WSNs, enabling them to evaluate, compare, and apply appropriate networking solutions for real-world wireless communication applications.
