Broadcast transmissions are currently finding extensive applications in vehicular ad hoc networks, albeit primarily in the research phase. Given the importance of knowing the updated network details of every node in the network, it is required to have a thorough understanding of the behavior of the broadcast scheme. In this paper, we study the performance of a single hop broadcast network having non-saturated nodes using analytical methods. Such a network characterization aptly captures the vehicular communication scenario, where depending upon whether the surrounding topology is sparsely or densely populated with nodes, the network switches between experiencing saturation and non-saturation. This work considers both these network conditions and also prioritizes the message into two categories as emergent or routine messages which exclusively caters to characterizing safety applications in VANETs. On these assumptions, a performance analysis is carried out using MATLAB simulations and the results are presented.
