Performance Evaluation of MANET Routing Protocols Based on Size and Speed Parameters

Abstract

Mobile nodes in Mobile Ad Hoc Networks (MANETs) play a dual role, functioning both as routers and hosts. This dual functionality enables them to receive incoming traffic and direct outgoing traffic. Energy efficiency stands as a critical factor when it comes to routing protocols. It plays a pivotal role in conserving the battery life of nodes involved in routing network traffic. In the scope of this research, we evaluated three routing protocols: TORA, OLSR, and GRP. Our analysis focused on their performance across various key metrics, including throughput, network end-to-end delay, and network load. To validate our findings, we conducted simulations within an office network environment measuring 1000m x 1000m, leveraging the OPNET Modeler 14.5 network simulation tool. The results of our simulations revealed that the OLSR protocol demonstrated the highest network load among the three protocols. In terms of network end-to-end delay and throughput, the OLSR protocol demonstrated superior performance compared to both the GRP and TORA protocols. Conversely, when it comes to network load, the TORA protocol outperformed both the GRP and OLSR protocols. On the other hand, the GRP protocol excelled in comparison to the TORA protocol when considering network end-to-end delay and network throughput.
