Drone swarm will pick up WiFi at the scene of a disaster

by admin

Reliable communication is a critical factor in the work of emergency services and rescuers who deal with the aftermath of a natural or man-made disaster. But sometimes disasters occur in extremely remote areas where only satellite phones work. How do you get a normal network up and running for the whole group?

The Laboratory of Self-Regulating Systems at the Polytechnic Institute of Lausanne has developed a project SMAVNET (The Swarming Micro Air Vehicle Network), which should solve this problem. They propose to use a swarming network of ten drones, which will organize a wireless network over a wide area in a few minutes. It is enough to throw them in the air (video of the network deployment process under the hubrakat).
The advantages of such a system are quick deployment time, wide coverage radius, cheap equipment, and easy startup (the protocols are designed in such a way that even a non-specialist can easily start up the network).

Each robot is made of a lightweight form of polypropylene, weighs 420 g, and has a wingspan of 80 cm.
Elevons on the wings are used to control the aircraft. The electric motor is mounted in the rear and the lithium-polymer battery lasts for 30 minutes of autonomous operation. The autopilot controls altitude, speed, and turning radius. The microcontroller built into the autopilot uses a minimalist strategy, obtaining data from just three sensors: a gyroscope and two pressure sensors. The drone controllers are made on a Toradex Colibri PXA270 board running Linux. A GPS module and a ZigBee transmitter (XBee PRO) are needed to record the trajectory of the drone.

As you can see in the first video, to deploy the WiFi network, all you have to do is turn the drones on and drop them in the air. Landing needs to be initiated from the ground interface.
The second video explains drone swarm communication algorithms (borrowed from ants).
