(事前公開アブストラクト) LPWANs are promising networking technologies to achieve data gathering for the Internet of things (IoT) devices. Due to share license-free bands, different services providers may deploy LPWANs for different service purposes, which incurs serious collisions. In order to address the above problem, we propose a scheduling based pulse-coupled oscillator (PCO) model with slot jumping. In the proposed method, each node adjusts own transmission timing based on the PCO model. When detecting the collision, it decides the next transmission timing by means of historical local information. Through simulation-based evaluation, we show that the proposed method achieves high data gathering ratio with reasonable convergence speed. |
