    77== PROJECT OVERVIEW

     9With the advent of the Internet of Things (IoT) revolution, there is an increasing need to develop low-cost physical layer security protocols for devices. This will reduce the computational power that is required and propagate energy savings to potentially tens of billions of IoT devices.  This project proposes a computationally simpler solution that uses Metamaterial antenna arrays that scramble the signal for eavesdroppers from undesired directions. This is called Directional Modulation.

     12Previous researchers who have worked on this idea have successfully used Directional Modulation to securely transmit small amounts of data using low bandwidth. A problem arises however when larger amounts of data are transmitted, which require more bandwidth. It turns out that the Metamaterial Antenna is frequency-dependent. This means data sent on subcarrier waves with large differences in frequency ranges will be affected differently by the antenna, resulting in errors.

     14The solution to this problem, and the focus of our research this summer, is called Symbol Precoding.
