A class of networks called VANET(vehicular adhoc network) ,the extension of MANETs(mobile adhoc network) are based on the principle of the formation of wireless network for exchange of data and the creation of network is spontaneous in nature. The mobility constraints, behavior of driver, high speed, limited coverage of wifi, hard delay constraints leads to unique characteristics in VANETS. So the MANET routing protocols are not suitable for VANET. Optimization of routing protocols becomes necessary to make it suitable for VANET. In this paper , various optimized routing protocols are analyzed and their optimization techniques are discussed. Parameters such as end to end delay and energy spent are taken into consideration in order to show the improvement from the routing protocols that are standard protocols. Then a method has been proposed to optimize the fine tuned OLSR (optimized link state routing)protocol with the use of advanced genetic algorithm to further improve the results and to make the protocol more efficient

The primaryaim of an ad-hoc network routing protocol is accurate and efficient route creation between node pairs so that messages may be delivered promptly. Route creation need to be done with reduced overhead and bandwidth. This paper presents a scheme to reduce bandwidth and power by the hibernation of nodes for a limited time. The effect of our proposal is then studied by simulation under various conditions and the analysis of the simulation results is done to comprehend the working of our protocol in various areas and how it fares in an application specific scenario.


The emerging new form of mobile adhoc network VANETNetwork is exemplifiedby fast and drastic changes in topology over a shorter period of time. These two features have a significant impact on the efficiency ofrouting protocols used in these networks. The evaluation of various VANET routing protocols provides great feedback on the efficiency of the network. The efficacy of AODV, OLSR, DSDV and DSR protocols is evaluated in this analysis, within the VANET intersection. The movement patterns of vehicles are generated with SUMO and the simulator is NS3.Considering VANET's high velocity, frequent disassociation and highly evolving topology, the major challenge is to create a routing protocol that is more appropriate to efficiently routing packet to their end destination. System of measurementsuch as power consumption, packet distribution factor, average performance as well as maximum end-to-end delay being calculated

VANET is a subset of Mobile Adhoc Network (MANET) that utilizes wireless technology, which in the VANET network the node is presented as a vehicle and the route for a vehicle is presented as a highway that will be passed by that vehicle. In general, VANET has 3 classification routing protocols, namely reactive, proactive, and hybrid. Performance of routing protocol is greatly influenced by the propagation model. Propagation on the network is the behavior of radio waves, which in this case is used as a transmission medium from the transmitter to the destination (receiver). This research will analyze the variation of propagation models namely FreeSpace,   TwoRayGround, Shadowing, and Nakagami on the performance of AOMDV (reactive), OLSR (proactive), and ZRP (hybrid). The performance of the routing protocol will be tested using test parameters including Packet Delivery Ratio (PDR), Packet Loss, End to End Delay, and Throughput. Keywords: VANET, AOMDV, OLSR, ZRP, FreeSpace, TwoRayGround, Shadowing, Nakagami
