Abstract

Abstract: The commonly used channel simulators always focus on the characteristics of RF signals at the receiver. However, they are costly in real-time simulation for spatial information network with multi-link and dynamic topology change. In this paper, a scalable simulator architecture for spatial information network, a simulation method for dynamic topology and channel propagation characteristics based on baseband data packages are presented. Based on this, a real-time spatial information networks simulation platform is designed and implemented. The platform can simulate the channel propagation delay, bit error, and dynamic topology changes for spatial information network. It supports 16 to 256 emulated nodes and up to 1024 links with dynamic topology change for spatial network. The delay and bit errors rate (BER) (1e-3 to 1e-9) can be configured for each link independently. When the data rate is 100 kbps, the propagation delay range can be configured from 1 millisecond to 20 minutes.
