The Probability of Connectivity in the 2 Way / 2 Lane Platoon-Based V2I Communication Network

Abstract

Congestion on major highways can be alleviated by moving in platoons. By exchanging information about their vehicles over VANETs, platoon members may keep the distance between their vehicles and inside the platoon consistent. To be sure, the strength of a VANET's connections can be gauged in part by its connection quality. This research investigates the probabilities of access, reachability and the connectivity between nodes (vehicles) and roadside-units (RSUs) in a two-way platoon-based VANETs that make use of such infrastructure. We call this the connectivity probability, and it is the likelihood that, during a given number of hops, moving vehicles on the express-way will be able to reach at least (1) RSU other than the road. In addition to looking at the connection on the same route, we also look at the link via vehicles on nearby surrounding roads and how they connect to the RSU. The analytical results (mathematical equations and calculations) have been validated by simulations, which show that a network's existence of platoons can boost the likelihood of connectivity. There is a greater chance of connectivity in a vehicle-to-infrastructure (V2I) network with multiple communication channels than in a network with only one. The results of this study can help eliminate the traffic jams and promote safer, more considerate motorists. Then everyone who is using the roads can travel in greater ease and security. These findings also provide substantial theoretical support for the design of a relish intelligent transportation system (ITS).
