Routing protocols are pivotal in determining communication network efficiency and reliability, particularly in mobile ad hoc networks. Landmark Routing (LANMAR) and Location-Aided Routing (LAR1) are two notable protocols in this domain, each offering distinct approaches to route discovery and maintenance. In this research, we conducted an in-depth comparative simulation study between LANMAR and LAR1 routing protocols using QualNet software. The primary aim was to assess and contrast their performance across essential metrics such as packet total packet enqueued, carried load broadcast, average jitter broadcast, and originated carried load. Through extensive simulations performed under varied network scenarios and traffic conditions, we analyzed the behavior and efficacy of both protocols. The results obtained offer valuable intuition into the pros and cons of LANMAR and LAR1, aiding network designers and researchers in selecting the most appropriate routing protocol for specific MANET applications. This research provides a thoughtful analysis of LANMAR and LAR1 routing protocols’ performance in MANETs, enabling informed decision-making for network deployments and protocol enhancements. This research not only shows the relevance of routing protocols in contemporary networking but also highlights the critical role of QualNet in advancing the field of network simulation.
