Global Positioning System (GPS) could be a navigation system using satellites that shows location and time data all told atmospheric condition to the user, orthogonal of position. GPS technology uses satellites and ground stations that has created a bearing on navigation and positioning desires of people. It's the flexibility to trace craft, cars, cell phones, boats and even people that become a reality. These all confer with out of doors navigation that¿s simply potential with the assistance of GPS navigation. However what if we wish to navigate in indoor environments? To achieve correct Indoor Position, we tend to could use the thought of increased Reality. It has been associate degree upward trend between the demand for indoor positioning systems victimization Wi-Fi, Bluetooth low energy, and visual light-weight communication. Numerous centroid Localization Algorithms are used. During this paper, we've got discuss one among the centroid localization algorithms i.e. Weighted centroid Localization (WCL) rule victimization Received Signal Strength Indicator (RSSI) measured by nearby anchors nodes. The WCL is simulated in an exceedingly explicit setting and analyzed to tac
