| Abstract | ||
| The instructions give the basic guidelines for Wireless Local Area Networks (WLAN) can be constituted for localizing wireless-enabled clients where GPS and GLONASS are unattainable due to multipath and signal blocking. Advances in unmanned surface vehicles (USVs) missions require a reliable navigation system to be controlled autonomously. A wireless sensors network becomes a necessary local positioning service (LBS) in a cooperative USVs. Many techniques are used to estimate client position in a wireless network. They are based on the characteristics of the received wireless signals: power, time or angle of arrival. In this paper a survey of positioning techniques and location based services in wireless networks is discussed. A practical application method of localization with use of WiFi of access points is applied in real time. A number of algorithms and techniques based upon different characteristics and properties of sensor nodes have already been proposed for this purpose. Results of system operation are considered with different arrangements of access points in a given space. | ||
