BUS-VANET:A BUS Vehicular NetworkIntegrated withTraffic Infrastructure

ABSTRACT:

With the development of wireless communications,Vehicular Ad Hoc Network (VANET) has receivedconsiderable attention on information sharingand data delivery services. In order to collect and controltraffic conditions, Intelligent TransportationsSystems (ITS) has deployed anumber of Road Side Units (RSUs)along the roads to collect anddeliver traffic information tothe Traffic Control Center(TCC) for analyzing trafficdata. Although someVANET architectureshave been proposedbased on the predictableroutes and schedules ofbuses, none of them consideredtaking advantageof such traffic infrastructureswhich already beensupplied by ITS and combinethem with scheduled buses. Inthis paper, we propose a two-tierBUSVANET that is fully integratedwith RSUs and TCC as traffic infrastructures.In this new architecture, the communicationsof vehicles, not only benefit from the existenceof buses, but also consider the effects of using RSUsand TCC. RSUs are used to ensure service coveragewhile TCC is helpful for locating the destination vehiclequickly. We also investigate how much benefitscan be obtained by taking advantage of this type oftraffic infrastructure.

EXISTING SYSTEM:

In existing, they have proposed the trajectory based statistical forwarding (TBD) for finding the vehicle as the next hop to minimize the delivery delay from a vehicle to a RSU. Vehicles have to share their trajectory with others for the encounter time prediction. In this way, vehicles can select the next hop based on the estimated encounter point with less latency. However, these trajectory based routing algorithms are hard to be realized in the real-world since people may not want to share their own trajectories considering the privacy issue. In mobile infrastructure based MANET, introduced architecture of a two-tier VANET, in which buses constitute the backbone for data delivery. One tier is the vehicles while another composed of the buses. However, their way of computing the connection time constrains that vehicles cannot change their speeds and directions. They also did not consider taking advantage of traffic infrastructures to improve the VANET performance.

DISADVANTAGES OF EXISTING SYSTEM:

  • Did not take the advantage of traffic infrastructure
  • Vehicles cannot change their speed and direction
  • Existing routing protocols are hard to be realized in real world

PROPOSED SYSTEM:

We propose a new BUS-VANET architecture which fully integrates traffic infrastructures with buses and vehicles. We consider how to take advantages of RSUs and TCC that already been provided by ITS to improve the VANET performance. Based on the proposed BUS-VANET, we use the registration technology to improve the transmission performance and provide a new method of selecting registration node to reduce the number of switches from common vehicles to high-tier nodes. We also proposed a new scheme for identifying the destination location more efficiently.

ADVANTAGES OF PROPOSED SYSTEM:

  • Improves the traffic performance
  • Identify the destination location more efficiently
  • Higher delivery rate and shorter delivery delay
