“…All roads are two-way with one lane per direction and there are buildings around them, which is treated as 2D polygons obstacles for modelling the obstacle shadowing, Fig. 12 shows an intersection instance of this area, and we use the obstacle shadowing loss model [3] to simulate propagation loss in the urban city. The travelling routes of all vehicles are chosen randomly.…”

“…Depending on whether the forwarding decision is made by the receiver or sender, the protocols can be classified as receiver-oriented and sender-oriented schemes. In receiver-oriented schemes, when candidate forwarders receive messages from the current forwarder, they will contend to forward the message in a distributed manner, choose a random number from contention window [3] or calculate waiting time based on various factors [4]. However, most of them depends on the fixed distance.…”

“…For delivering nonsafety messages, one-sixth of the total bandwidth in the SCH interval is used if only one of the SCHs is used [28]. The authors in [29] by analytical means calculate the maximum CW size. They rely upon the relative distance and SNR values between the communicating entities.…”

“…The generation of emergency messages is triggered by an event. The assumptions above are common and have been supported by several performance studies [1619]. Furthermore, we only consider the packet loss caused by the simultaneous transmission within the communication range and the hidden terminal problem.…”
