Enhancing TORA and Analyze with AODV Routing Protocol in Vehicular Ad-hoc Network for Traffic Engineering

Mobile Ad-hoc Network is a type of wireless network, which consists of mobile wireless nodes and the communication between mobile nodes is carried out without any centralized administrator. Vehicular ad-hoc network is a type of wireless network and it is a particular kind of Mobile Ad-hoc Network, which is exists in the form of vehicle to vehicle, vehicle to Infrastructure, and Infrastructure to Vehicle communication. So vehicular ad-hoc network is one of the interesting research areas in mobile networks. Routing protocols used in networking environment are considered to play an important role towards the performance, reliability and efficiency of the communication system. Among the different types of routing protocols, those are used in VANET environments to support the transportation system, reactive topology-based routing protocols are selected because of their dynamic characteristics in designing the routing table when it is needed. In this research we attempt to enhancing TORA and analyze the performance with AODV routing protocol in traffic engineering to ensure the quality of service issues for the help of intelligent transportation system. In this research, network simulator version 2 is used for the implementation and performance evaluation of the protocols. Moreover, evaluation of AODV and TORA performance was made through three different scenarios based on the number of nodes participating in the network. The result obtained by the simulation is compared in different scenarios by using the network performance metrics. The result shows that the average simulation result of AODV and TORA by using different performance metrics, AODV delivers superior quality of service than TORA, but based on throughput performance metric alone TORA outperforms when the number of nodes is smaller.
