Error analysis of range-based localisation algorithms in wireless sensor networks

摘要: Location information is essential when dealing with Wireless Sensor Networks (WSNs). This paper focuses on the error analysis of range-based localisation algorithms in WSNs. The mainly derived from measurement error. As seen through prior literature, researchers often assume similar measuring noise, which not rational practice. However, attempt this process to locate characteristic noise different. By a large number simulation experiments, has obtained quantitative relationship between location accuracy and errors occurring all data meets same conditions. In addition, we provide different effects distance estimation unknown sensor nodes. Users are able recognise effect accuracy, design more effectively.
