N. Tayade Information Technology Government College of Engineering Amravati – India ABSTRACT Clustering is a technique used in network routing to enhance the performance and conserve the network sources. This paper presents analysis between cluster-based routing protocols for VANET in urban scenario. The simulation results allow us to reach a conclusion as to which protocol among AODV, DSDV, and GPSR can be better implemented on the basis of Packet Delivery Ratio, Packet Delay, Frame Collision Rate and Signaling Rate in our scenario.

INTRODUCTION With the development of vehicles and mobile Ad Hoc network technology, the Vehicle Ad-hoc Network (VANET) has become an emerging field of study. Many potentially useful applications have been envisioned in vehicular networks [8] [9]. It is a challenging problem for searching and maintaining an effective route for transporting some data information. Some modern vehicular applications that aim at improving the users’ safety e.g. emergency remote control [10] require a video data throughput of up to 4 Mbit/s and a control packet delay in the order of milliseconds. Among all the proposed routing protocols, we chose to compare Ad-hoc Online Distance Vector (AODV), Destination- Sequenced Distance-Vector Routing (DSDV), and Greedy Perimeter Stateless Routing (GPSR) because they are the best-known protocols belonging to their own categories: reactive, proactive table-driven and proactive position-based protocols, respectively [11]. II. LEVEL OFCOMMUNICATION A. RSU TO RSU Each VANET node is typically attached to an On-Board communication Unit (OBU) which stays in the duty of providing communication with other nodes and/or Road- Side communication Unites (RSUs)Maintaining the Integrity of the Specifications RSU-RSU (infrastructure level communications). The first allows the vehicles to locally communicate in an ad- hoc manner and forward network traffic to each other. The second provides communication between the vehicles and RSUs to report network data such as lane traffic, road safety and/or congestionstatus. III. HARDWARE/SOFTWARE OMNeT++ (Objective Modular Network Testbed in C++) is a modular, component-based C++ simulation library and framework, primarily for building network simulators. OMNeT++ can be used for free for non- commercial simulations like at academic institutions and for teaching. OMNEST is an extended version of OMNeT++ for commercial use cases.OMNeT++ itself is a simulation framework without models for network protocols like IP or HTTP. The main computer network simulation models are available in several external frameworks. A. INET INET is built around the concept of modules that communicate by message passing. Agents and network protocols are represented by components, which can be freely combined to form hosts, routers, switches, and other networking devices. New components can be programmed by the user, and existing components have been written so that they are easy to understand and modify. INET benefits from the infrastructure provided by OMNeT++. Beyond making use of the services provided by the OMNeT++ simulation kernel and library (component model, parameterization, result recording, etc.), this also means that models may be developed, assembled, parameterized, run, and their results evaluated from the comfort of the OMNeT++ Simulation IDE, or from the commandline. B. Veins Veins, an open-source model library for (and a toolbox around) OMNeT++, which supports researchers conducting simulations involving communicating road vehicles—either as the main focus of a study or as a component. Veins already includes a full stack of simulation models for investigating cars and infrastructure communicating via IEEE 802.11p based technologies in simulations of Vehicular Ad Hoc Networks (VANETs) and Intelligent Transportation Systems (ITS). Thanks to its modularity, though, it can equally well be used as the basis for modeling other mobile nodes(like RESEARCH ARTICLE OPEN ACCESS
