| Abstract(in English) | Although wireless camera sensor networks are useful and powerful means of monitoring and surveillance, the high volume of video data would cause serious network congestion and degradation of perceived video quality for the limited capacity of wireless communication. In this paper, we propose an autonomous control mechanism of video coding rate, where each node autonomously determines its coding rate based on information obtained through local communication. For this purpose, we applied a reaction-diffusion model, which explains the emergence of variety of animal coat patterns. A spot pattern of video coding rate, which is centered at the target position and spreads towards the moving direction, is generated through local interactions among neighboring nodes. Simulation results show the effectiveness of our proposal. |
