Evaluation of Base Station Placement Scenarios for Mobile Node Localization

Abstract

The growing interest in utilizing short-range wireless for object positioning is compounded by the inherent GPS limitations. In order to harness the highest accuracy out of short-range positioning systems, we need to optimize the placement of Base-Stations (BS) in a given area. Hence, we need to study the impact of different influential attributes on the positioning problem as we alter the BS placement approach. In this paper we investigate different scenarios for short-range BS placement that maximize coverage and minimize the offset and strength of positioning error. Simulation results demonstrate that the optimal layout tends to be uniform placement of BSs in the area.
