Enhancing DotBot Network Efficiency: Using TDMA to Increase Gateway Capacity
SHARE
Said Alvarado Marin presenting a demo on DotBot TDMA Demo at Inria Paris.
DotBots communicate with a central gateway to receive commands and transmit measurements.
However, a single gateway can handle only up to 5 DotBots due to radio packet collisions when multiple devices transmit simultaneously, causing data loss.
To address this, we implemented a Time Division Multiple Access (TDMA) scheme, enabling DotBots to coordinate and take turns transmitting.
This approach prevents collisions, and allows a single gateways to manage up to 100 robots.
