Vehicular ad hoc networks (VANETs) are upcoming
prominent technology in the field of communication with
vehicles. It is a combination of mobile and sensor network
features. The random change in position of vehicles in VANET
made the system more vulnerable to attacks. The most important
attack in VANETs to be considered is Black hole attack which
increases the chances for packet loss and in turn to accidents.
There is a necessity to develop the techniques to detect Black
hole attacks and reduce number of accidents. In this paper, a
technique called “Detection of Black hole in VANET using
AODV (DBVANETuAODV)” is proposed to find and prevent
Black hole attack and thereby reducing occurrence of accidents.
The proposed solution is implemented using AODV Routing
protocol in VANET.The experiments are conducted with SUMO
and NS2 simulators to depict network environment in an
inexpensive way. The proposed method “DBVANETuAODV” is
compared with AODV with black hole and the result shows the
proposed method provides a significant improvement.
