Performance Evaluation and Discrimination of AODV and AOMDV VANET Routing Protocols Based on RRSE Technique

The routing protocol is an applied standard to determine the communication schemes of different entities with each other to transfer and process the desired data in considerable time via the best routes from the source to the destination. This paper presents the performance evaluation and discrimination for various parameters of two different routing protocols using the Root Relative Squared Error (RRSE). The two protocols under study are Ad-hoc On-demand Distance Vector (AODV) and Ad-hoc On-demand Multipath Distance Vector (AOMDV). The literature review reveals the simulation results of a number of nodes that varies approximately between 5 and 450 nodes. Therefore, that the simulation results will be analyzed for two different experiments as follows: the first, the effect of initial node energy variation between 50 and 100 J at a fixed network size. Whereas in the second, it reveals the impact of the network size, which varies between 50 and 450 nodes at constant initial node energy which is tested between 50 and 100 J. The obtained results of the selected parameters prove that the AOMDV protocol is more efficient, robust, and reliable than the AODV protocol for the first experiment, while the RRSE values of AODV are better for the second. Moreover, the proposed technique based on the RRSE algorithm is advantageous for comparing the two routing protocols.
