Geographic routing(GR) is a significant routing mechanism in wireless sensor networks (WSN) due to its simplicity and efficiency. Virtual coordinate systems were proposed to assign each sensor a relative coordinate. However, geographic routing using virtual coordinate faces several issues such as local minimum and inaccuracy of distance estimating. According to observations, these issues are caused by nonorthogonality and inaccurate hop-count distance. In this paper, a virtual coordinate assignment system with power control mechanism is proposed to generate fine grained and directional coordinates. In addition, we proposed axis calibration mechanism to be used in geographic forwarding to deal with the nonorthogonality of the coordinate system. As shown in simulation results, two proposed mechanisms are effective shrinking delivery path length and reducing packet routing failure rate.
