In this project, the author basically aims to use 3 sensors to form a wireless sensor network for the localization purpose of an indoor system. The researchers together with several research communities involved wish to achieve a relatively accurate position prediction of object in the indoor system and numerous localization methods based on Bluetooth, 802.11 technology, ultrasound, etc. have been proposed. During the process of this project, wireless sensor network is selected as the medium to predict the unknown position of the 4th sensor position which represents the unknown position of the object. Received Signal Strength Indicator (RSSI) is the main indicator for us to monitor the signal communication and thus predict the unknown position.
