Performance Demonstration of Decentralized TDMA Based on Desynchronization of Nonlinear Oscillators with Different Coupling Schemes

Abstract

The design of Media Access Control (MAC) protocols for the IoT has become important owing to the rapid growth in the number of IoT devices. To realize efficient and largescale wireless networks, autonomous distributed time division multiple access (TDMA) has been studied in previous research. We previously proposed a distributed TDMA suitable for the massive IoT network, which is based on the desynchronization phenomenon of a nonlinear oscillator network with intermittent and inhibitory couplings. In this paper, we propose a performance improvement method for our desynchronization method by changing the coupling functions of nonlinear oscillator networks. Our simulation results demonstrate that the convergence time to achieve a desynchronization state for TDMA communication can be reduced by modifying the coupling functions, such as the linear and cosinusoidal functions.
