Pi Car Comm
Contents
Introduction
Overview
The goal of this project is to establish vehicular communication between a group of PiCars. The end goal is to demonstrate this capability, specifically as it applies to collision avoidance between two or more vehicles.

Objectives
- Establish an ad hoc network between many (potentially up to 10, at least 2) Pi Cars
- Use this communication capability to avoid collisions in a demonstration involving at least 2 Pi Cars
Challenges
Data Transfer Rate
As the cars will be moving quickly, one of the main challenges will be ensuring that each car can establish and modify its network extremely quickly. Thus, not just data transfer, but also network establishment speed will be important.
Additionally, simultaneously addressing all valid addresses will be difficult to do efficiently.
Security
Since we're using Wi-Fi, there is a potential for a malicious actor to transmit faulty messages that could trick a car.
Fortunately, since the Pi's and/or cars will not be connected to the internet, a malicious actor would have to be physically close to the car (within the range of the Wi-Fi), substantially limiting the number of potential attackers.
