Abstract Connected vehicle applications rely on Dedicated Short-Range Communications (DSRC) technology for exchange of critical safety and efficiency information. The performance of underlying DSRC network greatly impacts how the applications perform. However, it is very difficult, if not impossible, to evaluate application performance under different DSRC communication conditions and in particular at large scale. As a result, researchers resort to simulation of DSRC networks for the purpose of determining possible issues that may exist for application performance. In this chapter we describe how connected vehicle applications can be simulated, with an emphasis on high fidelity but efficient simulation of underlying DSRC networks. Different approaches to simulation of DSRC are summarized and the sub-frame based method, which has widespread use, is discussed in detail. We present several enhancements to widely used discrete event simulators (such as ns-3) for the purpose of enabling sub-frame level simulation of DSRC. The resulting simulator is evaluated and shown to be accurate when comparing to results from field tests. In addition to sub-frame processing, which mostly concerns how wireless frames are processed in a node, the channel or propagation model is also discussed. The channel model stages and components are described and its use in the simulator is also explained.
