Table 14: Overhead (kbps) Obtained in Scenario R with Three Drops considering AMR-WB Modes 2 and 8. According to the presented results, the scenario where 7 drops occurs, the e-RLRP obtains better performance in all cases compared to BATMAN and OLSR, and also it presents a better performance than RLRP in most of the scenarios. In general, the performance gain in scenarios R was lower than in scenario P. This behavior is because, in the scenario P the drops are recurrent in only one route, which facilitates the learning process of the e-RLRP. Figure 8 demonstrates the e-RLRP performance improvement in relation to the other protocols. The _Ppl_ values obtained is the average of the results obtained in the four topologies and both AMR-WB rates modes used in the tests. \begin{table}
