On October 2, 2018, Mada’ Abdel Jawad, Saeed Salah and Raid Zaghalpublished a new study in the “World of Computer Science and Information Technology Journal (WCSIT) ISSN: 2221-0741 Vol. 8, No. 4, 24-31, 2018” titled “Performance Comparative Study of DSDV, E-DSDV, I-DSDV and O-DSDV MANET Routing Protocols”. The articleaimed to compare the performance of four well-known routing protocols for MANETs, namely: DSDV, E-DSDV, I-DSDV, and O- DSDV. The performance metrics that were considered in this analysis are packet delivery ratio, throughput, end-to-end delay, and routing overhead. Several simulation scenarios were carried out using the Network Simulator tool (NS3) by varying the number of nodes, pause time and velocity.
The results of this study demonstrated that in low mobility environments, I-DSDV outperforms the other protocols in terms of packet delivery ratio and network throughput, but this has led to a noticeable increase in routing overhead. In other scenarios the protocol performance was very similar to the DSDV performance. When compared to DSDV, O-DSDV does not show a performance improvement at low mobility environments and at slow speeds, but it gave the best performance at high mobility and high speed (especially speeds over 25 m/s). This is due to the fact that this protocol is adapted to fit highly- dense networks. Also, the results have shown that the E- DSDV had the least routing overhead in all scenarios and the highest end to end delay. This can be understood because E- DSDV canceled settling time concept and was not designing to select the shortest path. In terms of high-density environment there is no significant differences between the studied protocols.
