Performance Evaluation of OLSR and AODV Routing Protocols with different Parameters in Mobile Ad-hoc Networks using NS2 Simulator

Wireless sensor networks have become increasingly popular thanks to the great advances in the field of telecommunications. Indeed, the sensor nodes that constitute these networks have shown their effectiveness in monitoring and remote control of the physical environment with better accuracy. However, the implementation of such a system poses many problems where optimizing energy consumption remains one of the major research challenges. Our goal in this article is to ensure good quality of service and routing of information to treatment stations to extend the life of the entire network while saving the energy spent by each network sensor. This article presents two routing methods for wireless sensor networks, namely Optimized Link State Routing Protocol and Ad-hoc On Demand Vector Protocol. Our performance analysis was based on various parameters such as throughput, Packet Delivery Fraction and End-to-End Delay to ensure good resource utilization, improve security and better scalability. The results obtained from the simulation were evaluated on the NS2 simulator and gave a better performance of the routing protocol in terms of reliability, robustness and energy conservation.
