"Reduction of Quality (RoQ) attack is one of the Denial of Service (DoS) attacks which affect the MANETs. Instead of refusing the clients from the services completely, these RoQ attacks throttle the TCP throughput heavily and reduce the QoS to end systems. To mitigate this RoQ attack in MANET, the authors propose to design a distributed defense technique in this paper. Initially, a mechanism for monitor node selection is designed such that the monitoring nodes should cover the entire network. These monitoring nodes estimate the short-lived flows to observe the sudden increase in the traffic load in a short time."
