    The integration of autonomous unmanned aerial vehicles into both civilian and mili-
    tary applications creates a potential risk for cyber-attacks. The wireless communication
    link used to monitor and control the UAV may be vulnerable to attacks in the absence of
    encryption. With publicly available information regarding the communications protocol,

    The integration of autonomous unmanned aerial vehicles into both civilian and mili-
    tary applications creates a potential risk for cyber-attacks. The wireless communication
    link used to monitor and control the UAV may be vulnerable to attacks in the absence of
    encryption. With publicly available information regarding the communications protocol,
    autopilot, and ground control station software, obtaining the necessary knowledge to per-
    form a malicious cyber-attack can be relatively easy. In the past it has been an uncommon
    practice to use encryption to secure communication in non-military UAV applications, due
    to the increased latency. This paper presents an investigation on the increase in latency
    due to encryption using the Digi 2.4 GHz XBEE-PRO 802.15.4 and 900MHz XBEE-PRO
    900HP DigiMesh which are commonly used for command and control communication in
    low cost UAVs.

  • AIAA Science and Technology Forum and Exposition 2017

    Invited to present paper titled, “Investigating Encrypted IEEE 802.15.4 and DigiMesh Communications for Small Unmanned Systems” at the AIAA SciTech Forum 2017 in Grapevine, TX. Paper published by AIAA

  • Undergraduate Research Assistant with the VIP Collaborative UAV Team

    -

    • Worked on GCS Dashboard JAVA android application, which provides GCS operator with real-time attributes of UAV through a TCP connection
    • Expanded application by developing maps display using Mapbox API’s and integrating with GCS Dashboard
    • Maps provide real-time tracking of UAV during flight; maps of selected regions are cached and rendered for offline use

  • Senior Capstone Project

    -

    • Contributed to design of a data acquisition system to monitor the brake performance of a vehicle incorporating real-time brake-line pressure and temperature reading capabilities; The system is integrated with a GPS system to track speed, acceleration and deceleration, as well as provide maps of routes taken
    • Data is viewed overlaying on a map, implemented with a Google Maps web page applet, to show where events occurred
    • Device also displays real-time information at runtime regarding…

    • Data is viewed overlaying on a map, implemented with a Google Maps web page applet, to show where events occurred
    • Device also displays real-time information at runtime regarding brake temperature and pressure, along with device status messages for error reporting and brake squeal detection, on a small LCD display.

  • Microcomputer Systems

    -

    - Designed a robot to complete the following tasks: maze navigation, line follow, and draw an Image, in C language
    - Created an android app that sends characters via Bluetooth to control the robot. Robot was programmed using ARM Cortex-M3 microcontroller
