Dynamic Two Layer based Clustering for Smart Vehicle Coordination in Bi-Directional Road Scenario

Abstract

Today the scene in self-driving vehicles have drastically changed and continue to continuously evolve. Thus, there is a necessity for a communication protocol that enables the communication between vehicles of different manufacturers, that is, there is a necessity for an open standard. Proposed solution range from V2V (vehicle to vehicle communication) that primarily uses AD-HOC and V2I (vehicle to infrastructure communication) that uses an Access point. This Access point may be a fixed one like on the road side or un-fixed on like on a car. However it is implemented we would need a specialized on-vehicle communication unit to use V2V or V2I technology. This paper aims to provide a improved solution which reduces the amount of data being communicated by clustering smart vehicles in a tree like hierarchy. It also aims to provide the basic foundation for scheduling and to build the cluster by the use of nomination of a vehicle to become the access point limited to the cluster and to communicate with its parent node. We also calculate the signal-to-noise-interference ratio (SINR model) to test for the applicability of said proposed system. Thus, by extension we also provide an argument that supports the need for such a system.
