Abstract :
Road accidents and traffic jams are the most important problems on the roads. Wireless Access in Vehicular Environments (WAVE) can be used as preemptive and informational measure. WAVE builds multi-path communication between vehicles and infrastructure nodes, where nodes share emergency and other information. In this paper we analyze the delay of emergency message transmission in multi-hop link, based on IEEE 802.11 and draft IEEE 802.11p. Simulations in NCTUns 5.0 environment show that single message propagation is in permissible range even for 100 nodes. Several scenarios simulated show that trade-off between reliability and message delivery latency exists.
