Collaborative Warning System for Dense Vehicular Networks Using MUSIC Algorithm DoA

The problem of providing a collaborative early warning system for multiple moving vehicles against a small size fast moving object like a motorbike. This approach consists of three stages: The first stage consists of detecting the incoming object using a highly directive antenna at 5.0 GHz in license free industrial, scientific and medical (ISM) band. The second stage consists of broadcasting the warning message using a low directivity broad beam antenna, third stage will be detected by receiving vehicles by using direction of arrival (DOA) estimation technique. The position of a fast arriving object can be estimated using the MUSIC algorithm for warning beam DOA estimation. This paper is intended to demonstrate the feasibility of an early detection and warning system using a collaborative vehicle to vehicle communication links. The simulation is performed to show the behavior of detecting and broadcasting antennas as well as performance of the detection algorithm. The process can be further expanded to implement commercial grade detection and warning system.
