Poster: Synchronizing Devices with Minimal Data Exchange and Applications for Graph-Based SLAM

For synchronization purposes, most applications require data to be transferred onto a cloud or shared with other edge devices. Transferring data between edge devices using wireless connectivity consumes power and bandwidth; therefore it is crucial to transmit a minimal amount of data. This poster presents an efficient method and preliminary analysis for minimizing data flow between edge devices and experimental results on the amount of transmitted data with radio use of $e$(-Nm), where n is the maximum difference between wake-up times and m is the number of devices that wake up at arbitrary time points. Besides the amount of data, our approach also focuses on the radio use of each device.
