A Relay Vehicle Selection Scheme for Delivery of Emergency Message Considering Density and Trajectory of Moving Vehicles for VANET

摘要: Dissemination of safety alert messages through the broadcast is one most important applications for VANET. Excessive channel contention due to simultaneous transmission packets leads storm. To reduce and redundant messages, it requires an effective multihop relay vehicle selection scheme. Therefore, we propose a scheme delivery emergency message considering density moving vehicles In this paper, far from previous while belongs tolerant angle selected as next hop in distributed manner. analyze its performance, evaluate number hops candidate participating competition accessing wireless channel. Simulation results show that numbers can be reduced by application adequate with location window size.
