“…The results of the study in [14], suggested that a slight change in communication range results in a major difference in connectivity probability in the case of high vehicle density. Further, to maintain the connectivity of vehicles transmission range plays an essential role [15][16]. Mostly, a larger range of communication results in a large area covered within transmission range which helps to enhance link connectivity performance as compared to small transmission range.…”

Vehicular ad-hoc network (VANET) uses 'mobile internet' to facilitate the communication between vehicles and with the goal to ensure road safety and achieve secure communication. Thus the reliability of this type of networks is of paramount significance. The safety-related messages are disseminated in VANETs, on the wireless medium through vehicle to vehicle (V2V) and Vehicle to roadside (V2R) communications. Hence, the Reliability of network is an essential requirement. This paper considers the effect of vehicle transmission range and vehicle density on the connectivity probability. In addition, a reliability model which takes into account minimal safe headwayamong nearby vehicles at highway tunnel is specified. The reason is that under the tunnel Global Positioning System (GPS), a component of onboard unit (OBU) needs a rich line of sight for perfect services, because due to signal interference, the GPS does not work properly. Though, in the case of a fully connected network, there are chances of danger between vehicles which are close to each other. Therefore, the network is not safe, as accidents and collision can happen at any time. Hence, maintaining the minimal safe headway distance under the tunnel is interesting and useful for VANET. The obtained results show that the little difference of the minimal safe headway under the tunnel can cause a serious change in the entire network reliability. Suggesting that while designing the network reliability models the safe headway cannot be ignored.

In order to understand the message propagation performance in Mobile ad-hoc Networks (MANETs), various methods and models have been proposed in the literature by applying a common pairwise meeting rate between mobile nodes. In this paper, based on this classical meeting rate, we develop an Ordinary Differential Equations (ODEs) based analytical framework aiming at depicting the propagation process of a target message while using a controlled epidemic routing protocol. Each relay node is assigned a threshold value of its buffer can be occupied by the target message copies in such the controlled epidemic routing. Further, we also investigate the effect of the threshold to the total buffer occupancy ratio over all the relay nodes using our proposed theoretical framework. The correctness of our analysis is validated by extensive simulations.
