Research on Network Scalability Based on UWB Indoor Localization System
Hainan University, Haikou and 570228, China
Network Scalability is an important step in the development of UWB indoor localization system. Owing to its fine resolution and robustness in cluttered environments, UWB signals are well suited for localization purposes as they allow high ranging accuracy. TDOA algorithm based on UWB indoor localization system can achieve high-precision positioning but it requires each anchor clock synchronization. This paper mainly studied the optional of master anchor based on TDOA algorithm. It becomes an effective way to adapt to the complex communication environment. Then realized the network scalability in multiple anchor conditions and finally evaluated the performance of master anchor optional algorithm on a realistic indoor scenario. A localization error analysis on UWB indoor positioning system was performed. The smallest TDOA measurement error is 15.127 cm and the worst error is 27.230 cm, as was shown by the test results.
