Broadcasting is used when messages are applicable to all nodes in the network. Such types of messages are common to all nodes in the vehicular network. In the vehicular network, various information is provided by the trusted authority (TA) to RSUs and vehicles. This information is applicable to all nodes under TA. RSU also holds information which is used for authentication of vehicles. RSU also holds CRL (Certification Revocation List) list to check the validity of vehicles. It is broadcasted in the network if required [6].
A Review on V2V Communication for Traffic Jam Management
Published in Fei Hu, Vehicle-to-Vehicle and Vehicle-to-Infrastructure Communications A Technical Approach, 2018
Broadcasting incurs high network traffic causing contention, collision, and redundancy because all nodes continuously transmit data, which is known as the broadcast storm problem [32]. This problem exacerbates when a traffic jam occurs since there are a large number of vehicles in a limited space performing the beaconing process. It is thus of importance to prioritize different types of messages so that important messages can be transmitted with a higher priority [19]. Also, the ACK message can be selectively sent for lightweight messages while preventing the sending of an ACK message for heavyweight messages, and the frequency of message transmission can be dynamically adjusted to reduce the network traffic [9]. To alleviate the broadcast storm problem, some approaches allow for beaconing only when a certain event occurs, for example, when the vehicle velocity becomes less than a threshold [20,21].

From Figure 20.1, the input of video source is first compressed in the VCL into a bitstream. The function of the VCL is to efficiently compress the video content. The NAL is a new concept, which is designed for efficient transmission of the compressed bitstream in different network or storage environment which includes all current and future protocols and network architectures. These applications include broadcasting over terrestrial, cable, and satellite networks; streaming over IP-networks, wireless, and ISDN channels. In this layer, the head information is added to the coded bitstream for handling a variety of transport layers or storage media. The interface of NAL is designed to enable a seamless integration of the coded video data with all possible protocols and network architectures.
Understanding users’ continuous content contribution behaviours on microblogs: an integrated perspective of uses and gratification theory and social influence theory

A microblog is a typical We Media (Bowman and Willis 2003; Gillmor 2003); this means every user can have their own voice. Making their voice heard by more people is one of the main purposes of users (Goffman 1959). Users may use microblogs to announce events or make self-presentations. As a result, microblogs share an attribute with traditional media, broadcasting, which most users value greatly. Broadcasting represents the process of message dissemination in a communication network whereby a message originated by one member is transmitted to all members of the network (Hedetniemi, Hedetniemi, and Liestman 1988).
Asynchronous broadcast-based decentralized learning in sensor networks

In general, solving (1) in (wireless) sensor networks requires careful algorithm design. Broadcasting is usually preferred in sensor networks since communication is more energy and time consuming than computation. In addition, broadcasting can improve the consensus speed by diffusing information to more nodes with the same amount of cost. However, huge amount of coordination is required for this dynamic network if a synchronous algorithm is used. In contrast, an asynchronous method such that each node can decide its action independently would be more appropriate in this situation.
The new face of mimicry consumption: understanding the mediating role of social media

Earlier studies have found that most Instagram users make purchases while or after browsing posts on Instagram (Salpini, 2017; Smith, 2018). According to Yang (2016), different types of social media content influences consumers differently. Yang (2016) categorised Instagram use into three types: interaction, browsing, and broadcasting. She defined interaction as the communication directly involving other people on Instagram, while browsing is reviewing newsfeeds/homepages and viewing other profiles without leaving any comments. Broadcasting is sharing information with a broad audience rather than specific individuals. Based on Yang’s (2016) classification of Instagram activities, the present study examines how these three types of Instagram activities mediate the relationship between subjective well-being and mimicry consumption. Therefore, the following hypotheses are proposed: H2. Instagram activities will mediate the relationship between subjective well-being and mimicry consumption behavior.H2a. Instagram interaction will mediate the relationship between subjective well-being and mimicry consumption behavior.H2b. Instagram browsing will mediate the relationship between subjective well-being and mimicry consumption behavior.H2c. Instagram broadcasting will mediate the relationship between subjective well-being and mimicry consumption behavior.Figure 1 shows the proposed model with research hypotheses.
