Quality of Service for data traffic is an important facet of a network, which in the case of a wireless network can easily be disrupted by applying a device to broadcast signals. The authors believe that the increased of the energy consumption, when a jamming attack occurs, can be used as a guiding indicator in order to mitigate the attack. The authors show that when a reactive jamming attack occurs on a wireless network unmitigated, it can easily block the entire data traffic to the point there is no data can be delivered. The authors also show that, using NS3 simulation, in an event where a reactive jamming attack to the network happened, the source of the attack can be identified through the increased of energy consumption , and successfully mitigated by avoiding sending data traffic through the same channel used by the attacker, by executing channel hopping.
