Developing Multipath Routing Protocol Based on Source Routing Protocol in MANET

Abstract

Mobile Ad hoc Networks (MANETs) provide a flexible solution for establishing networks in environments where conventional infrastructure is unavailable, such as disaster areas or military operations. However, routing in MANETs is a critical challenge due to node mobility and limited resources. Numerous protocols have been developed, though their performance varies in various conditions. This study paper introduces a multi-disjoint route technique built on the source routing principle, designed to improve MANET performance for the sake of meeting Quality of Service (QoS) requirements. The performance evaluations of the proposed on-demand multipath source routing protocol using NS-2 in comparison with other DSR-based protocols, namely Modified-DSR, Extended-DSR, and Updated-DSR, the results have suggested that the proposed on-demand multipath source routing protocol has obvious advantages in terms of Packet Delivery Ratio (PDR) and Normalized Routing Load (NRL) over the common existing routing protocols developed for MANET.
