A Study on the Impact of Mobility on the Performance of Routing Protocols in MANET-Based Online Learning Platforms

ABSTRACT

A rapid development in online learning systems to maintain the continuity of student education during the COVID-19 pandemic has been observed. The telecommunication technologies based on Mobile Ad hoc Network (MANET) are very useful and widely used to connect online learners staying remotely in jungles, forests and hilly areas where it is difficult to establish permanent infrastructure for communication. Routing protocols play a vital role in the background, which provide an uninterrupted learning session. In this context, by considering the mobile gadgets and other electronic devices as the nodes of the MANET system, it becomes quite imperative on the part of the researcher to further analyze and understand the impact of node mobility on the performance on MANET-based online learning systems in rural Indian terrain. A change in mobility can be achieved by changing the online learner's node speed during its movement or by changing the pause-time at its halt points during its random movement. Change in mobility causes link breaks between neighbor learners nodes;hence, a large number of packets drop in the network, which in other terms reduces the network performance and, simultaneously, the reliability of the online learning system. The performance of the MANET-based online platform is analyzed by taking parameters like packet delivery fraction, normalized routing load and average link break. This paper thoroughly discusses the performance variation due to change in mobility. © 2023 selection and editorial matter, Zdzislaw Polkowski, Samarjeet Borah, Sambit Kumar Mishra, and Darshana Desai;individual chapters, the contributors.
