Abstract

Safety is the only way home. Broadcasting techniques have been applied widely to improve the traffic safety, especially pileup crash avoidance by sending the emergency messages to alert drivers; however, such application often suffers from the broadcast storm, hidden node, interference, and contention problem. In the paper a novel area-based broadcast protocol was proposed. Its relaying model running at the receiver side based on the position and velocity properties of the sender and the receiver can deliver the emergency message very fast. The simulation results show that not only can it take 8.5 ms with 11 retransmissions in average to disseminate 3.5 km away from the sender but also it has the less delay and retransmission rate in comparison with other protocols.
