  Vehicular Ad Hoc Network (VANET) is a type of mobile ad hoc network (MANET)
that facilitates communication among vehicles. VANET provides inter-vehicular
communications to serve for the application like road traffic safety and
traffic efficiency. Infotainment service has been an anticipating trend in
VANETs, and video streaming has a high potential in VANET. Although, this
emerging technology is trending, there are still some issues like QoS
provisions, decentralized medium access control, node coverage area, and
finding and maintaining routes due to highly dynamic topology. These issues
make multicast communication difficult in VANETs. Numerous routing protocols
and routing strategies have been projected to cope with these issues. Lots of
work has taken place to assess and measure the performances of these protocols
in VANETs but these protocols are rarely analyzed for performance under stress
of real time video multicast. In this study two different multicast routing
protocols viz. Multicast Ad hoc On Demand Distance Vector (MAODV) and Protocol
for Unified Multicasting through Announcements (PUMA) are evaluated for
facilitating video streaming in VANETS. The protocols are examined against the
QoS parameters such as Network Throughput, Packet Delivery Ratio (PDR), Average
end to end Delay, and Normalized Routing Load (NRL). Variable Bit Rate (VBR)
traffic is used to evaluate the performances of protocol. PUMA, at the end,
showed better performance against different QoS provisions in different
scenarios
