Simulation of Vehicular Ad-hoc Network Routing Protocols with a Performance Analysis

Vehicular Ad-hoc Network (VANET), a subset of Mobile Ad-hoc networks (MANETs), is one of the emerging technologies of Road Transportation system. In recent years, the aspect of Vehicular Ad-hoc Network (VANET) is becoming an interesting research area as it is characterized as self-configured wireless network. The design of routing protocols in VANETs is play a vital role and necessary issue for the Vehicle to Vehicle Communication Technology. The existing routing protocols of MANETs are suitable for VANET with changes in configuration of protocol. The routing protocols fall into two major categories of topology-based and position-based routing. We discussed different kinds of existing routing protocols with two major categories, the advantages and limitations of each which will helps to enhance the existing routing protocols for the suitability of Vehicular Ad-hoc Networks. We implemented three existing routing protocols and the testing results stated that the performance of each in aspects of various parameters such as Packet Delivery Ratio, Throughput and End-End Delay using Network Simulator

An Optimized Node Selection Routing Protocol for Vehicular Ad-hoc Networks – A Hybrid Model

Vehicular Ad-hoc networks (VANETs) are a subset of Mobile Ad-hoc Networks made by vehicles communicating among themselves on roadways. The Routing protocols implemented for MANETs such as Ad-hoc on Demand Distance Vector Routing Protocol (AODV), Dynamic Source Routing (DSR), and Destination Sequence Distance Vector Routing Protocol (DSDV) are not suitable for VANET due to high Mobility. Trusted routing in VANET is a challenging task due to highly dynamic network topology and openness of wireless architecture. To avoid a frequent communication link failure, to reduce the communication overhead and to provide a trusted routing among the vehicular nodes for achieving high packet transmission, we implemented an Optimized Node Selection Routing protocol (ONSRP) of VANET based on Trust. In our proposed work, we implemented an enhanced routing protocol which prevents the network from communication link failure frequently. The testing results stated that the ONSRP routing have a high performance measures than the above mentioned existing routing protocols
