Abstract

Trilateration is one of the most used method in the place position calculation with help of distance calculated using\nvarious methods like Bluetooth Low Energy (BLE), Wireless fidelity (Wi-Fi), ultrasonic and etc. As this method is a viable\nsolution because of its less hardware requirement. But in the basic trilateration, accuracy is not so much targeted since it\nassumes that distances given to algorithm for the calculation of position are accurate. A small error leads to large variance in\nthe position estimation. So, the proposed algorithm is enhanced such way that it estimates position with less errors even\nthough estimated distances are not so accurate.
