An experimental system of mobile robot's self-localization based on WSN

Mobile robot's self-localization is an important part of robot technology research. This paper first briefly introduces several main methods of mobile robot's localization, and RSSI (Received Signal Strength Indicator) ranging principle. Then it proposes an experimental system which is used for mobile robot's localization based on wireless sensor network (WSN), and describes the experimental system's structure in detail. According to outdoor experiments, it proves that the system operates perfectly. Based on the experimental results, we provide some suggestions for improving the localization algorithm, facilitating further algorithm research.
