The technology made an easy way of communicating by allowing devices to communicate each other. The group of mobile devices communicated each other grouped in small or large cluster is a platooning, where a group of autonomous cars following each other at closer distance with the benefits of increasing road capacity, fuel savings, and quick response at any mission as there is no suddenly halt of human manoeuver. In this work an orchestration of vehicle communicate wirelessly through any communication channel based on the transmission of any vehicle is platooning. Thus every vehicle is equipped by a group of sensors for facilitating this communication .
In some cases error may occur suddenly. In this regard an integrity of communication between vehicles is in question and needs a deep study, the Symbol Error Probability(SEP)between vehicles is analyzed by considering the transmitted power, channel mean gain and interference levels, all-in function of the number of vehicles involved in platooning. The effect of noise generated through the channel, transmitted power, channel gain, interference level and platoon size are captured through numerical results and interpreted on graphs
