Description
Summary:This paper proposes a new anchor placement algorithm for improving localization performance. Motivated from the result obtained on the anchor placement error analysis (Shi et al., 2005), an near-exhaustive search is done on anchor placement for localization variance. Based on the best anchor area found in the search, we design a selective mobile anchor placement scheme (SAP). Simulation result shows that the SAP anchor placement scheme is effective in a sensor network with a small anchor ratio. Localization simulation result shows both the position variance and accuracy are improved by more than 10% of the radio range.
