Wireless network channel quality estimation inside reactor building using RSSI measurement of wireless sensor network

It has always been a technical challenge for operations service team to expand wireless network reception inside reactor buildings (RB) and their service wings (SW). This is driven by the volume of metal equipment inside the Reactor Buildings (RB) that blocks and somehow shields the signal throughout the link. In this study, to improve wireless reception inside the Reactor Building (RB), an experimental model using indoor localization mesh based on IEEE 802.15 is developed to implement a wireless sensor network. This experimental model estimates the distance between different nodes by measuring the received signal strength indication (RSSI)Then by using triangulation and RSSI measurement, the validity of the estimation techniques is verified to simulate the physical environmental obstacles, which block the signal transmission.
