Gr802.11 Jamming Detector, Grant A. Blake
Computer Engineering
One important component of a jamming-resistant 802.11 network is detecting the presence of a jammer during normal operation. This is required so that communications on the network can operate at full efficiency when no jammer is present, but switch to a less efficient, but more resilient protocol when the network is under attack. This paper describes a potential method for detecting some common forms of jamming, lays out a plan to test the effectiveness of the detection method, and summarizes the implementation and results of the test plan.

Computer Engineering
PLANR is a self-contained robot capable of mapping a space and generating 2D floor plans of a building while identifying objects of interest. It runs Robot Operating System (ROS) and houses four main hardware components. An Arduino Mega board handles the navigation, while an NVIDIA Jetson TX2, holds most of the processing power and runs ROS. An Orbbec Astra Pro stereoscopic camera is used for recognition of doors, windows and outlets and the RPLiDAR A3 laser scanner is able to give depth for wall detection and dimension measurements. The robot is intended to operate autonomously and without constant human monitoring …
