To simulate the Vehicular Ad-Hoc Networks (VANETs) using OPNET which permits to design and examine the vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) interaction. VANETs are significant for applications such as traffic management, collision avoidance, and infotainment systems.
Now, we deliver detailed guide to configuring and executing the VANET simulation in OPNET:
Steps to Simulate VANET Projects in OPNET
- Define the VANET Network Topology:
- Configure a topology with vehicular nodes like cars, trucks, buses and roadside units (RSUs) that perform as base stations or relay points.
- Organize the nodes to signify a real-world road network, along with vehicular nodes are tracking predefined paths along highways, city streets, or rural roads.
- Location RSUs at strategic points such as intersections or along highways that to make easy V2I communication.
- Configure Mobility Models for Vehicular Nodes:
- Utilize the Mobility Profiles to replicate realistic vehicular movement patterns:
- Predefined Path Mobility: Describe routes for each vehicle mimicking movement along roads.
- Random Waypoint Mobility: Utilize it for experimenting in open situations without certain paths.
- Then, set the speed variations toward reflect the urban (low-speed), suburban (medium-speed), and highway (high-speed) environments.
- Select and Configure VANET Communication Protocols:
- Set up protocols generally utilized within VANETs for V2V and V2I communication:
- For direct V2V communication, using Dedicated Short-Range Communications (DSRC) or IEEE 802.11p
- Cellular V2X (C-V2X) for V2I communication in which vehicles interact with RSUs through cellular infrastructure.
- For efficient short- and medium-range interaction, configure RSUs and vehicular nodes along with suitable communication standards, frequencies, and transmission power.
- Set Up VANET-Specific Routing Protocols:
- Utilize ad-hoc and specialized routing protocols to handle the dynamic vehicular network conditions:
- AODV (Ad hoc On-Demand Distance Vector) or DSR (Dynamic Source Routing) for reactive routing in which routes are launched as required.
- GPSR (Greedy Perimeter Stateless Routing) for geographic-based routing in which vehicles route data according to its geographic location.
- Set up every single vehicle with the chosen routing protocol that allowing adaptive routing depends on the real-time mobility and network topology modifications.
- Define Traffic Models and Applications:
- Describe diverse VANET applications utilizing Application Configuration and Profile Configuration:
- Safety Messages: Configure periodic disseminates of safety messages like collision warnings, lane departure alert, which need low latency.
- Traffic Information: Replicate the applications that gather and broadcast traffic data for congestion management.
- Infotainment Services: For passengers, we can set up non-critical applications such as video streaming or internet access.
- Allocate the traffic profiles to each node including higher priority for safety-related requests and lower priority for infotainment.
- Configure Quality of Service (QoS) for Different Applications:
- Set the QoS policies to give precedence safety-critical messages:
- High priority for V2V safety messages along with strict latency needs.
- Lower priority for infotainment traffic that can endure more delay.
- Make certain that latency-sensitive safety applications are initially processed utilizing priority queues and bandwidth allocation settings.
- Run the Simulation with Defined Parameters:
- Describe the simulation parameters, like duration, data collection intervals, and event capture settings.
- Begin the simulation and then observe real-time data flow with vehicle mobility, communications among V2V and V2I, and message broadcasting over the network.
- Analyze Key Performance Metrics:
- Utilize OPNET’s analysis tools to assess the VANET performance, which concentrating on metrics like:
- End-to-End Delay: Calculate the delay amongst transmitting and receiving safety messages that is significant for real-time V2V applications.
- Packet Delivery Ratio (PDR): Estimate the percentage of packets effectively delivered, which especially for safety messages that need reliably attain neighbouring vehicles.
- Throughput: Measure the data rate attained for infotainment and other non-critical applications.
- Handover Success Rate: Monitor how frequently vehicles hand off communication amongst RSUs within V2I situations that estimating network continuity.
- Interference and Signal Strength: Examine the influence of high vehicle density on signal quality, which specifically in crowded urban situations.
Example VANET Project Ideas
- V2V Safety Message Performance: Configure a VANET along with high-priority safety messages and then estimate the performance metrics like end-to-end delay, packet delivery ratio, and network reliability within high-speed highway conditions.
- Traffic Management with V2I Communication: Replicate a network with RSUs to crossings and utilize the traffic data applications to examine the congestion management and vehicle flow enhancements.
- Infotainment in Dense Urban Areas: Set up a VANET with infotainment services within a dense urban configuration and calculating how network congestion and QoS prioritization influence the service quality.
- Comparing DSRC and Cellular V2X for VANETs: Configure a mixed network along with both DSRC and C-V2X nodes, which investigating performance dissimilarities such as delay, throughput, and network reach.
