The Southeastern Librarian
Librarians today are wrestling with an everchanging digital environment. In some way oranother, we must all adapt to new technologies, skills, and ways of thinking. What comes to mind when you hear the word “metadata?” Is itintimidating? Do metadatists and catalogers explain the term adequately? While this articleby no means captures all there is about metadata, it is intended to provide librarians with a basic understanding of what is involved in metadatawork.

With the rapid development and wide deployment of wireless Local Area Networks (WLANs), WLAN-based positioning system employing signal-strength-based technique has become an attractive solution for location estimation in indoor environment. In recent years, a number of such systems has been presented, and most of the systems use the common Nearest Neighbor in Signal Space (NNSS) algorithm. In this paper, we propose an enhancement to the NNSS algorithm. We analyze the enhancement to show its effectiveness. The performance of the enhanced NNSS algorithm is evaluated with different values of the parameters. Based on the performance evaluation and analysis, we recommend some …
