Summary:
With the rapid increase in Internet of Things (IoT) devices, the design of Median Access Control (MAC) protocols for IoT has become more important. Autonomous decentralized Time-Division Multiple Access (TDMA) methods have been studied in previous research to achieve efficient and large-scale wireless networks. In our previous research, we proposed a decentralized TDMA scheme with intermittent inhibitory coupling, which is suitable for large-scale IoT networks based on the desynchronization phenomenon of non-linear oscillators. In this paper, we propose a method to improve the performance of this desynchronization method by changing the coupling function of the non-linear oscillator network. Simulation results showed that changing the coupling function, such as linear or cosine functions, can shorten the convergence time of desynchronization more than the general sinusoidal function.
