A hierarchical vehicle position encoding scheme in inter-vehicle communication networks

This paper proposes a hierarchical vehicle position encoding scheme for inter-vehicle communication networks (IVCN) and describes the way to derive the best performance using the proposed scheme under a specific condition. It is also shown that the proposed scheme can suppress the position error on transmission caused by channel noise which is lower than that of the uniform energy assignment scheme, and where the signal energy is equal to that of the proposed scheme.
