This study enhances Vehicular Ad Hoc Network (VANET) communication for intelligent traffic lights by combining DSDV and AODV routing protocols. The DSDV-AODV protocol shows improved performance in delay, QoS, and throughput for traffic management.
Area of Science:
- Intelligent Transportation Systems
- Wireless Communication Networks
- Network Routing Protocols
Background:
- Dependable communication technology is crucial for advanced traffic systems.
- Vehicular Ad Hoc Networks (VANETs) are key for intelligent traffic lights, accident management, and congestion reduction.
- Effective routing protocols are essential for reliable data transfer in VANETs.
Purpose of the Study:
- To improve data transmission in VANETs for intelligent traffic light systems.
- To investigate the combined DSDV and AODV routing protocols for enhanced performance.
- To evaluate the DSDV-AODV protocol's effectiveness using the 802.11p wireless standard on the OMNET++ simulator.
Main Methods:
- Simulation of VANETs using the OMNET++ simulator.
- Implementation and testing of the DSDV-AODV combined routing protocol.
- Analysis of network performance based on delay, Quality of Service (QoS), and throughput metrics.
Main Results:
- The DSDV-AODV routing protocol demonstrated superior performance across delay, QoS, and throughput compared to individual protocols in simulated traffic intersection scenarios.
- A network topology with 50 fixed and 50 mobile nodes yielded optimal results: 0.00062s delay, 640 bits/s network QoS, and 629.437 bits/s throughput.
- Increased mobile nodes positively impacted delay and throughput metrics, though network QoS parameters showed poorer results.
Conclusions:
- The DSDV-AODV combined routing protocol offers a significant improvement for VANETs in intelligent traffic light applications.
- The proposed protocol enhances network reliability and efficiency for traffic management systems.
- Further research may explore optimizing network QoS with higher node mobility.
