Wireless Networks: Analysis of Routing Protocols (MN603)

This report provides an in-depth analysis of the LEACH and PEGASIS routing protocols within the context of wireless sensor networks (WSNs). Part A of the report investigates the motivation behind the adoption of these protocols, their categorization, and detailed individual analyses. The report explores the classifications of WSN routing protocols, specifically focusing on hierarchical routing and the subcategory of Network Organization Based Routing Protocols. Part B delves into the security aspects, including vulnerabilities, network attacks, and countermeasures for both LEACH and PEGASIS. The report identifies various security threats such as passive and active attacks, insider and outsider attacks and vulnerabilities like malicious nodes and compromised cluster heads. Countermeasures like secure clustering schemes and trust-based models are discussed. Finally, the report concludes with a comparative analysis of the two protocols, highlighting their strengths and weaknesses in terms of security, quality of service (QoS), and energy efficiency. The report offers a comprehensive overview of these protocols, their practical implications, and their role in optimizing WSN performance.
