Real-time and protocol-aware reactive jamming in wireless networks
First Claim
1. A real-time reactive jamming device for jamming signal transmissions in a wireless network, comprising:
- a real-time signal detector that detects an event in received packets in said wireless network;
a reactive jamming device that sends a triggering signal when said event is detected; and
a jamming generator responsive to said triggering signal to generate a jamming signal that has a user-defined delay so as to enable jamming of specific portions of received packets in the wireless network.

Abstract
A real-time capable, protocol-aware, reactive jammer using GNU Radio and the USRP N210 software-defined radio (SDR) platform detects in-flight packets of known wireless standards and reacts to jam them—within 80 ns of detecting the signal. A reactive jamming device is achieved using low-cost, readily available hardware. The real-time reactive jamming device includes a real-time signal detector that detects an event in received packets in the wireless network, a reactive jamming device that sends a triggering signal when the event is detected, and a jamming generator responsive to the triggering signal to generate a jamming signal that has a user-defined delay so as to enable jamming of specific locations in received packets in the wireless network. The effects of three types of jamming on WiFi (802.11g) and mobile WiMAX (802.16e) networks are demonstrated and jamming performances are quantified by measuring the network throughput using the iperf software tool.
