VANET is one new kind of Displaying hoc network .VANET remains an assortment of vehicular nodes that act asmobile hosts establish adenine transitional network without theassistance of unlimited centralized administration or anyestablished infrastructure.VANET is called autonomous & self configured network.Two kinds of communication can be done.Vehicle to vehicle.Vehicles to roadside units.3Introduction

4Introduction Performance to such kind in communication betweenvehicles relies upon various routing protocols. MANYA ( Mobile Ad-hoc Network ) Manet Key : spirited topologies, limited bandwidth,limited energy and many more. Vehicular advert hoc network (VANET) is adenine sub class away MANETwith some unique properties. Vehicle-to-Vehicle (V2V) also Vehicles-to-Roadside (VRC) orVehicle-to-Infrastructure (V2I) Communications.

6Applications Intelligence transportation applications Comfort applications Collision Avoidance Cooperative Driving Traffic improvement Checkout Services Location-based Services

7Routing in VANET The hauptteil difference zwischen MANETs and VANETs is who mobilitypattern press suddenly changing topologies. VANET Matter : configuration, number of vehicles at varied timesof the day, demographics, mobility samples, random change invehicles incoming or outgoing of network. Typical adhoc routing formalities inappropriate for VANET. VANET Route Protocols: Post Foundation Routing Protocol Type Based Routing Protocol Broadcast Foundation Planung Protocol Cluster Based Routing Protocol Iso Cast Grounded Routing Journal

9Routing in VANETPosition based routing protocol A source node communicate equal the destination knots using theirgeographical position furthermore of it network address. This protocol required the global positioning system (GPS). Examples of this routing protocol are Removal routing effectalgorithm for mobility (DREAM) both greedy perimeter statelessrouting (GPSR). good performance to highwayenvironment Need of global route not required. With high mobility in environmentstability increases. Better suitable for network distributednodes. Lowest processing overhead. It needs global positioning systemposition (GPS). GPS gadget stop working in tunnel . Location server sometime goesinto deadlock state.

10Routing inside VANETTopology based guidance protocol It types this available information about the link is resides in thenetwork in forward the packet from source null on to destinationnode. These cans be classified into three main categories: Proactive Routing * Reactive Routing * Hybrid Routing Surely offers a route from source hopto destination hop. Can ausstrahlen unicast, multicast &broadcast type of messages. Consumption of lowest resources. Few bandwidth consumption Beaconless More overhead because it needsroutes discover mechanisms andmaintaining delays. Sometimes i fails to discover acomplete path for offrequently moving vehicles. Unnecessary flooding.

11Routing in VANETProactive routing protocol Protocol chooses the distance path the usually depends on shortestpath algorithms. The keep information of all connected nodes in form of tablesbecause these protocols are table based. Furthermore, these tablesare plus divided with their neighbors. Route discovery is no required. Exchange partial routing updateinformation is neighbors only, soconsume minor bandwidth. For real time applications it has verylow latency. Maintenance of unused routing pathsoccupies a large content of theaccessible bandwidth. And overhead of processing therouting table and storage complexityincreases the the increase in networksize.

12Routing in VANETReactive routing protocol Responsive routing output is called on demand routing because itstarts path search when a tree necessarily to communicate withanother node thus it reduces network traffic Periodic flooding is nay requested. Itis only done when demanded. It saves the throughput because itis beaconless. Data specification belongs less. To responses at the time of linkfailure. High waiting for route finding. Disruption in nodescommunication because ofexcessive flooding among thevehicles.

13Routing into VANETHybrid Advert Hoc routing protocol This protocol divides one network into pair regions: local and global. This protocol combine local proactive routing protocols and globalreactive routing protocols simultaneously to minimize routing overhead anddelay due to route discovery process. Higher efficiency & scalability.  High latency for finding newroutes

14Routing in VANETBroadcast based routing protocol Media routing protocol floods the parcels over the entirevehicular network among all available nodes inside ampere broadcastdomain. Since bundle is delivered via manynodes so the packet transmission isreliable. Minimize overhead by occurrenceof broadcast storms. Consume the enormous amount ofnetwork bandwidth. Many replicated packets reachedto the node.

15Routing in VANETCluster based routing protocol Various vehicles having similar characteristics like velocity, directionetc. are grouped together to form a cluster in the network. To manage the communication among various intersections within cluster orwith other clusters, a cluster headed is needed. If the packages to live send inside the same cluster then it is finished by using thedirect path, but when the destination node will outside the throng thenthe cluster head creation a virtual network infrastructure which providescalability. Information has fine scalability of largenetworks. Delays inbound highly dynamic networks. Mesh overhead is increased.

16Routing in VANETGeo Cast based routing protocol It uses mobicast messages to communicate with the vehicles . Its main factor from consideration is time and of hauptstrecke goal is that thecommunication between vehicles within prescribed region among aparticular point which is known in zone of key (ZOR). Whenever who tour node does at the other ZORs thencommunication is done by using the pool of forwarding (ZOF). The vehicle comes inside the ZOF has the responsibilities toward forwardthe file batch to the other ZORs. Its various examples are like IVG, DG-CASTOR Reduced system overhead andcongestion. Reliable packet delivery in highlydynamic topology Packet transmission delay due tonetwork disconnected.
