Abstract
本稿では,スマートフォン位置特定サブシステムの性能や特徴の明確化のため,Bluetooth Low Energy (BLE)の位置特定性能の評価を行っている.疑似的に生成したReceived Signal Strength (RSS)と実環境で取得したRSSを使用して,BLEを使用した位置特定システムの性能や特徴の評価を行い,確率論的手法と決定論的手法の位置特定アルゴリズムによってNon Line Of Sight (NLOS)の影響が位置特定性能への影響が異なることを示している.実験結果から特徴の異なる位置決定アルゴリズムの協調による位置特定性能改善手法の検討を行っている.以上のことから,位置特定アルゴリズムによる位置特定性能の性能や特徴の差を示す. This paper evaluates smartphone positioning performance using Bluetooth Low Energy (BLE) to clarify the performance and features of smartphone positioning subsystems. Using the pseudo generated Received Signal Strength (RSS) and the RSS logged in the real environment, we evaluate performance and features of BLE positioning system. We use probabilistic and deterministic methods as positioning algorithms. Evaluation shows that the influence of Non Line Of Sight (NLOS) on the positioning performance differs depending on the positioning algorithm. In addition, from the experimental results, we investigate a method of improving positioning performance by cooperation of positioning algorithms with different characteristics. Based on the above, we show the difference in performance and characteristics of positioning performance by the positioning algorithm.Copyright ©2018 by IEICEtextapplication/pdftechnical repor
