  Abstract

Medium Access Control(MAC) delay which occurred between the anchor node’s transmissions is one of the error sources in underwater localization. In particular, in localization for moving platform, e.g., AUV(Autonomous Underwater Vehicle), the MAC delay significantly degrades the ranging accuracy because of the differ packet reception times. In this paper, to analyze the impact of MAC delay, we define the Cramer-Rao Low Bound (CRLB) for the ToA-based localization. Furthermore, we introduce underwater localization combined with multiple access technology to decouple the impact of MAC delay from the localization. Toward this goal, we adopt hyperbolic frequency modulation (HFM) signal which has high-temporal correlation characteristic. Owing to the multiplexing ability, the anchor nodes can transmit their packet without MAC delay, i.e., simultaneous transmission is possible, leading to the remove the impact of MAC delay. The simulation results show that the proposed system provides high and stable localization performance as compared with the existing system that ignores the impact of MAC delay.
