General
Network Security Lab, University of Washington, Seattle has begun work on a wireless interference (jamming) model for ns3. The goal is to to enable researchers to use ns3 to study jamming and its mitigation methods.
Project Background
Interference (Jamming) in wireless networks is an important example of malicious attacks in wireless networks. It is achieved by deliberate transmission of radio signals to disrupt the communication in a wireless network by decreasing the signal-to-interference-noise ratio (SINR). Jamming leads to corrupted packets at the receiver, which results a lowered throughput.
Project Goals
To provide a simulation toolkit that allows researchers to easily implement and simulate a wireless jamming strategy or jamming detection/mitigation strategy. To enable researchers to evaluate the performances of jamming and jamming detection/mitigation strategies.
Jammer
Jammer is one of the key elements in the jamming model. It includes the following primitives to enable implementation of different jamming strategies:
- Transmit jamming signal.
- Adjust jamming power & duration.
- Extract packet headers.
- Scan, hop channels (for a multi-channel wireless protocol).
- etc.
Honest Nodes
A set of primitives is added to honest nodes to enable implementation jamming detection/mitigation strategies:
- Measure Packet Delivery Ratio (PDR).
- Measure Received Signal Strength (RSS).
- Scan, hop channels (for a multi-channel wireless protocol).
- etc.
