Improvement of QoS and Selection of Cluster Head using RSL Algorithm with Multipath Routing Protocol in MANET

The use of Mobile Ad hoc Networks (MANET) apps has been deployed in numerous regions that are inaccessible to humans. In sensor networks, however, routing remains a major issue since timely delivery of data to the base station is critical. Data transmission has been more dependable and scalable in recent years thanks to Multipath Routing. The concept of Quality of Service (QoS)-based routing is relatively new, with just a few protocols addressing it. The QoS is addressed in this paper using the clustering approach. Each cluster has a cluster head which is picked using the Random Selected Leader (RSL) based optimizer algorithm in this article. Using the Cluster Heads, the suggested method selects reliable pathways for data transmission based on factors such as energy consumption, latency, and congestion index costs. In contrast to current QoS Centric protocols, the suggested protocol leverages the optimal amount of pathways for data transmission and improves the network lifetime by deploying energy-optimized Cluster Heads. Simulated environments are used to test the proposed protocol's performance. According to simulation results, the suggested protocol surpasses current protocols in terms of throughput and network life.
