# GNU Radio Python Flow Graph
# Title: Jamming Detection in IoT Wireless Networks: An Edge AI-Based Approach
#
# Authors: Ahmed Hussain, Nada Abughanam, Junaid Qadir, and Amr Mohamed
# Conference: The 12th International Conference on the Internet of Things
# (IoT '22), November 7--10, 2022, Delft, Netherlands
#
# Functionality: This is assumed to be the receiver side. The aim is to
# record and convert the power transmitted by the jammer, to RSS samples.
