Geographic routing has attracted attention since it is a memory less and scalable approach. Two types of geographic routing protocols are proposed in the literature; those relying on exact position information using GPS, and other algorithms using Virtual Coordinate System (VCS). In recently proposed VCS, the unique identity cannot be easily assigned to any node due to the amount of reference points needed to produce a unique reference framework. This paper proposes a fundamentally different way of designing a new virtual coordinate system for localization in wireless sensor network which relies only on local connectivity information and per-neighbor communication.
