Abstract: | In urban vehicular wireless environments, several vehicles can send warning messages and so every vehicle within the transmission
range will receive the broadcast transmission, possibly rebroadcasting these messages to other vehicles. This increases the
number of vehicles receiving the traffic warning messages. Hence, redundancy, contention, and packet collisions due to simultaneous
forwarding (usually known as the broadcast storm problem), can occur. In the past, several approaches have been proposed to
solve the broadcast storm problem in wireless networks such as Mobile ad hoc Networks MANETs. In this paper, we present Street Broadcast Reduction SBR, a novel scheme that mitigates the broadcast storm problem in VANETs. SBR also reduces the warning message notification
time and increases the number of vehicles that are informed about the alert. |
