NetSim is a discrete event simulator covering a broad range of wired, wireless, mobile and sensor networks. It comes with a simple and user friendly GUI which features drag and drop functionality for devices, links, application etc. The specifications for the VANET module in NetSim v10 are –
Basic Safety Message (BSM) Protocol as per standard J2735 Dedicated Short Range Communications (DSRC) Message Transport Layer
Protocol source C codes available for user modification
Output Performance Metrics: A variety of network performance is reported including
Detailed Packet Trace: Users can log details of each packet as it flows in the network.
Detailed Event Trace: Users can log each event of the protocol FSM while execution of the discrete event simulation
Command Line Interface
MATLAB Interface: NetSim can be interfaced with MATLAB offline or online (run-time)
IEEE 1609 defines the architecture and provides the standards for Wireless Access in Vehicular Environments (WAVE) that defines vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) wireless communications. This standard provides the foundation for a broad range of applications in the transportation environment, including vehicle safety, automated tolling, enhanced navigation, traffic management and many others.
Simulation of WAVE based VANET Networks can be achieved by interfacing NetSim with SUMO (Simulation of Urban Mobility), an Open Source traffic simulation software. NetSim handles simulation of the WAVE wireless network communication between the vehicles, while road traffic conditions can be modeled conveniently in SUMO.
These VANET simulation features would be useful to engineers & researchers working on the communications architecture for DSRC - based V2V and V2I interactions.
LTE Based Vehicular Networks: VANET simulations based on LTE which is achieved by interfacing NetSim with SUMO. Road traffic conditions are modeled in SUMO and NetSim takes care of the network communication part. Vehicle mobility can be modeled along roads and per traffic signals.
