Abstract – A wireless communications will
always be affected by fading, interferences or hidden terminal problems. For
vehicle, an urban scenario is centre stage to roam around the concrete jungle.
Beaconing message is the most common communications which has an ability to let
the vehicle know about its neighbouring vehicle in order to choose a right
forwarder for non-safety or safety message. However, a congestion that resulting
in low messages and overhead beacon that caused by the influx of the broadcast
messages were give a negative impact in low message reception and in excessive
delay. An emergency messages may be affected as an interferences due to street
beacon, channel arbitration messages also with the other control messages which
share a common channel as specified by DRSC/WAVE. In this paper a scheme were
proposed in order to cancel an interferences by using adaptive transmission
control due to inter-street beacon communications, while at the same time
maintaining the application layer of the transmission range through network
coding and forwarding multi-chop beacon. From the simulation, it show that the
scheme produced more higher packet delivery ratio and higher successful channel
utilization compared with the CSMA/CA protocol.

Keywords- Congestion control, Interference,

I.             INTRODUCTION

     A lot of
attention has been witnessed from industry such as communication in vehicular
network as well as academia. This because of many applications such as, traffic
monitoring, driver assistance infotainment and collision notifications. From
the research conduct it show that the Internet and cloud has encouraged a cyber
penetration in a big way in a vehicular network. A lot of data application
required for the various intelligent transportation systems (IPTS) in order to
be able to communicate over Vehicle-to-Vehicle (V2V) and also a Vehicle
Infrastructure networks (V2I). In order to cater DSRC/WAVE safety applications
in a vehicular network, beaconing is an important necessity 3 where the
beacon can go up until 10 beacons per second in order to be able to deal with
the changes of the direction of the rear end and head on collisions of the
vehicles. Frequent beaconing is necessary in order to improve the accuracy of
the neighbourhood information since GPS error are inherent vehicular network in
real time. A significant amount of time were spent to commuting using either
private or public transport. A connection may establish between the vehicle and
the base station through a mobile gateway or directly 27.
