Scalable Urban Network Simulation (SUNS)
Abstract
A clear and accurate understanding of communication network performance is essential, especially where all layers of the protocol stack - from physical propagation to application transport protocols - must be accounted for. While some solutions exist for RF communications over "open-terrain" areas, the urban environment is particularly challenging. To meet this challenge, a server-based, real-time solution for assessing complex communication and network effects in urban environments has been developed. By combining advanced RF ray-tracing propagation modeling and a full network simulator, the Scalable Urban Network Simulation (SUNS) software is able to provide accurate communications effects services. SUNS supports tactical modeling and simulation by predicting electromagnetic signal coverage and path loss through application of a full 3D physical knowledge of the urban environment and terrain features. The commercial OPNET network simulator is used as the core of the system, with SUNS operations supported through a custom OPNET model that functions as a modeling and simulation server. The server, in turn, communicates with other node models within the OPNET simulation. In the approach, urban propagation data are pre-computed using high performance computing (HPC) resources utilizing ray traced models of the urban scene.
