Abstract:
Urban Vehicular Ad hoc Networks (UVANETs) are the most important form of mobile
ad hoc networks. It has been broadly used in intelligent transportation system(ITS) to
supply safety and comfort services to the passengers and drivers and also provide securi-ty/privacy using vehicle-to-vehicle and vehicle-to-road side unit(RSU) communications.
In UVANETs this research which maintains the security of the sensitive information
shared between vehicles and end-users. In addition to that we tested on different types
of attacks and provide possible solutions to handle these attacks. And different emerging
open challenges along with the security threats are identified and Detected and the power
of each nodes are also managed.
This research proposed geographical multi cast network mode to analysis the performance
of path selection routing protocols(PSRP) for UVANET because geographical multicast
network mode uses central coordinator or it constructs virtual central coordinates that
preserve enough neighborhood information to be useful in geographic routing but do
not require actual position determination and has moderate bandwidth. Due to these
benefits geographical multicast routing algorithm(GMRA) is used to handle security issue,
fault detection technique and power management. To simulate the proposed scheme,for
performance analysis network simulator-3(NS-3) version-3.23 (V-3.23) is used.
Simulation results show that, the PDR for five CBR connections, GMRA is 4 % and 7 %
better than GPSR and AODV routing protocols respectively. Similarly one can observe
the same advantages of GMRA at 10 CBR and 15 number of CBR connections. The
packet loss of GMRA is enhanced by 10 % and 7 % than GPSR and AODV routing
protocols respectively. And one can observe the same advantages of GMRA at 5 and 15
number of CBR connections. The delay of GMRA for the three CBR connections are
lower than GPSR and AODV routing protocols.
