At the 11th ACM International Workshop on Wireless Network Testbeds, Experimental Evaluation & Characterization (WiNTECH 2017) we publish a paper on "Massive Reactive Smartphone-Based Jamming using Arbitrary Waveforms and Adaptive Power Control". This repository contains source code required to repeat the experiments we did for our paper. Additionally, it allows fellow researches to base their own research on our results.
Any use of the Software which results in an academic publication or other publication which includes a bibliography must include citations to the nexmon project (1) and the paper cited under (2):

Nexmon: Build Your Own Wi-Fi Testbeds With Low-Level MAC and PHY-Access Using Firmware Patches on Off-the-Shelf Mobile Devices, In Proceedings of the 11th ACM International Workshop on Wireless Network Testbeds, Experimental Evaluation & Characterization (WiNTECH 2017), October 2017."
To compile the source code, you are required to first checkout a copy of the original nexmon repository that contains our C-based patching framework for Wi-Fi firmwares. That you checkout this repository as one of the sub-projects in the corresponding patches sub-directory. This allows you to build and compile all the firmware patches required to repeat our experiments. The following steps will get you started on Xubuntu 16.04 LTS:
- Install some dependencies:
sudo apt-get install git gawk qpdf adb - Only necessary for x86_64 systems, install i386 libs:
sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
- Clone the nexmon base repository:
git clone https://github.com/seemoo-lab/nexmon.git. - Download and extract Android NDK r11c (use exactly this version!).
- Export the NDK_ROOT environment variable pointing to the location where you extracted the ndk so that it can be found by our build environment.
- Navigate to the previously cloned nexmon directory and execute
source setup_env.shto set a couple of environment variables. - Run
maketo extract ucode, templateram and flashpatches from the original firmwares. - Navigate to utilities and run
maketo build all utilities such as nexmon. - Attach your rooted Nexus 5 smartphone running stock firmware version 6.0.1 (M4B30Z, Dec 2016).
- Run
make installto install all the built utilities on your phone. - Navigate to patches/bcm4339/6_37_34_43/ and clone this repository:
git clone https://github.com/seemoo-lab/wintech2017_nexmon_ping_offloading.git - Enter the created subdirectory wisec2017_nexmon_jammer and run
make install-firmwareto compile our firmware patch and install it on the attached Nexus 5 smartphone.
