Investigating Packet Transmission From the Perspective of Complex Networks Composed of Chaotic Circuits

Complex networks have been studied in various fields. In particular, topology and routing algorithms have been studied with the aim of preventing packet dropping and congestion in communication networks. When chaotic circuits are connected together to form complex networks, it is found that the synchronization rates around the high-degree nodes (hubs) are higher than those around low-degree nodes. By setting the coupling strengths between circuits while taking the degree of each node into consideration, it is possible for the synchronization rates around the hubs to be set to be significantly higher. Therefore, we propose a routing method that selects a route based on the high or low synchronization rates. As a result, it is confirmed that selection of a route with a low synchronization rate avoids congestion at the hubs and reduces packet dropping.
