1. A Suitable VehicularBroadcast Protocolunder DifferentTrafficPatterns
for Urban Scenario
Abstract:
VANETs have emerged as an exciting research and application area.
Increasingly vehicles are being equipped with embedded sensors,
processing and wireless communication capabilities. This has opened a
myriad of possibilities for powerful and potential life-changing
applications on safety, efficiency, comfort, public collaboration and
participation, while they are on the road. Although, considered as a special
case of a Mobile Ad Hoc Network, the high but constrained mobility of
vehicles bring new challenges to data communication and application
design in VANETs. This is due to their highly dynamic and intermittent
connected topology and different application's QoS requirements.. In this
work, we propose a new data dissemination protocol named as TURBO.
The TURBOaims is to eliminate the broadcast storm problem in dense
scenario and maximize the coverage in sparse scenario. TURBOprotocol
was compared with four well-known protocols from literature: AID, DBRS,
Flooding, and GEDDAI. Simulation results show that our proposed

2. protocol has performed better than other four protocols, outperforming
them in different scenarios in all the evaluations carried out.
