  • Abstract Broadcasting is a common operation for disseminating traffic-related information in vehicular ad hoc networks (VANETs). However, broadcasting in wireless networks can easily cause the broadcast storm problem especially in high vehicular density environment. Therefore, most of the broadcast storm suppression schemes aim to decrease the number of forwarders so as to reduce the redundant packet and mitigate the broadcast storm problem. One of the broadcast storm suppression techniques is the distance-based scheme [15] in which the relative distance between the sender and the receiver is used to decide whether to rebroadcast a message or not. However, this conventional distance-based scheme may cause the improper measurement problem called in this paper. So we propose the Limited Hop Number Weighted p-Persistence Broadcasting (LHNWpPB) to resolve this problem. The simulation results show the proposed broadcast storm suppression scheme can reduce the number of forwarders and also the redundant packets.
