Popis:	Broadcasting communications is critically important in vehicular ad hoc networks. Many safety applications need safety warning messages to be broadcast to all vehicles present in an area. Design of a broadcasting protocol for vehicular ad hoc networks is an interesting problem because of challenges posed by broadcasting traffic, high throughput, high reliability and low delay requirements of these networks. In this article, we present a mathematical analysis to explore the relationship between groups of parameters, namely contention windows, hidden/exposed vehicle nodes, reliability, throughput and delay of broadcasting protocol in vehicular ad hoc networks. Then, the multi-object optimization model is proposed to explore how to adjust the delay-throughput-reliability trade-off. The numerical analysis reveals that to keep balance between throughput, delay and reliability, the contention window of MAC may be dynamic adjust.
