Inter-vehicle protocol for cooperatively capturing and sharing bird-eye intersection video

For accident prevention in intersections which are occurring frequently in recent years, it is useful for drivers to grasp the position of vehicles in blind spots. In order to allow a driver to grasp the situation of an intersection intuitively, we consider an application where each vehicle in an intersection exchanges captured video with each other through inter-vehicle communication and these vehicles generate and display live bird's eye view video of the intersection. In this paper, we propose a method to select particular vehicles among all vehicles in intersection which send a video. In our method, in order to compose a high-quality video within available wireless bandwidth, each vehicle calculates priority of all vehicles for sending videos based on their position and direction, and selects some of the vehicles with high priority. For evaluation of the proposed method, we conducted simulation experiments by imitating an actual intersection with QualNet simulator. As simulation results, we confirmed that vehicles selected by our method can send high quality video capturing request areas in high density (the distance between vehicles is 10,[m] or less) environment with 60% or more carrying rate.
