Estimating the Relative Speed of RF Jammers in VANETs

Figure 7

Average MAE increase from the optimal zero MAE reference point with different evaluation parameters: the MAE of the proposed RSEA with different number of nodes for the contention window of the MAC back-off procedure for the wireless channel between - and different jammer’s speed values. (a) Average MAE (%) vs. different number of “hidden” nodes. (b) Average MAE (%) vs. range of jammer’s speed values (Km/h).
