“…Flooding mechanism has high speed of distribution but it is easy to cause broadcast storm. Therefore, Fukuhara et al [22] sorted EWM into forward and backward information to diminish the amount of relay messages. However, context [23] should be considered, without regional restriction, this method could cause the amount of messages stored in a relay node exceeds its limited storage and bandwidth capacities.…”

Emergency warning message (EWM) transmission insurance is one of the most interesting topics for vehicular ad-hoc network application. Clear channel assessment (CCA) threshold is deemed to be a key factor influencing EWM dissemination performance. Considering vehicle abnormal event hazard level and EWM's important level, a new parameter, EWM priority rank, is defined. Based on EWM priority rank, a new CCA threshold selfadjusting method is proposed in this paper. Moreover, according to the proposed CCA threshold selection method, an EWM dissemination algorithm is designed. A series of experiments on the sensor network testbed are conducted to evaluate the impact of proposed method on EWM dissemination. The experimental results show that an appropriate CCA threshold is beneficial to increase global dissemination success rate and to shorten packet delivery delay.

“…And a Received-Signal-Strength-Based broadcast and other three broadcast schemes are also proposed in [6]. In [7], the proposed protocol can provide broadcasts to a particular area and avoid mistakenly notifying other areas where the information is not needed, by limiting the broadcast direction.…”

Broadcast mechanisms are widely used in wireless adhoc networks, in this paper we proposed a novel on-demand virtual backbone broadcast protocol (OVB-CAST) for VANET. Our OVB-CAST supports safety applications based on WAVE architecture and it provides better adaptability and reliability than some other protocols by its fitness calculator and the ondemand multiple backbones. And we give a comparison between OVB-CAST and other broadcast protocols to show the advantages.

“…The methods used to solve BSP are divided into four schemes [10]: (i) probabilistic-based (ii) flooding-based, (iii) area-based (divided into location-based and distance-based) and (iv), neighbour-knowledge-based. Those schemes have widely been studied within the MANETs' environment, and there is much ongoing effort to mitigate the impact of BSP [11,12,13,14,15]. However, this problem is still in its infancy in VANETs [17,18].…”

In VANETs, there are many applications that use broadcast communication as a fundamental operational tool, in disseminating information of interest to other road users under the umbrella of both safety and entertainment applications. Recently, the probabilistic broadcasting scheme is suggested as an efficient broadcast approach. Although a number of probabilistic schemes found in the literature, they still suffer from a high level of rebroadcast redundancy, which often leads to the Broadcast Storm Problem (BSP). Thus, in this paper a new efficient probabilistic broadcast scheme is developed, to target both achieving a high delivery ratio and reducing broadcast redundancy. Using simulation experiment, we compared the performance of the proposed scheme against the recent well known probabilistic schemes and our results confirm the superiority of our scheme over existing schemes in terms of key performance metrics, namely Reachability (RE) and Saved Rebroadcast (SR).
