1. BUS-VANET: A BUS Vehicular Network Integrated with
Traffic Infrastructure
ABSTRACT:
With the development of wireless communications, Vehicular Ad Hoc Network
(VANET) has received considerable attention on information sharing and data
delivery services. In order to collect and control traffic conditions, Intelligent
Transportations Systems (ITS) has deployed a number of Road Side Units (RSUs)
along the roads to collect and deliver traffic information to the Traffic Control
Center (TCC) for analyzing traffic data. Although some VANET architectures
have been proposed based on the predictable routes and schedules of buses, none
of them considered taking advantage of such traffic infrastructures which already
been supplied by ITS and combine them with scheduled buses. In this paper, we
propose a two-tier BUSVANET that is fully integrated with RSUs and TCC as
traffic infrastructures. In this new architecture, the communications of vehicles, not
only benefit from the existence of buses, but also consider the effects of using
RSUs and TCC. RSUs are used to ensure service coverage while TCC is helpful
for locating the destination vehicle quickly. We also investigate how much benefits
can be obtained by taking advantage of this type of traffic infrastructure.

2. 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

3.  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
