Abstract

Sensor network is a group of sensors which can communicate each other among one and the other in certain range, and recently, the concern about sensor network system has been increasing. Sensors for temperature, humidity, object detection / determination so on are arranged everywhere. In sensor network system, sensors are connected mutually and positional information of each sensor becomes essential. Acquiring positional information will gives better service for advanced analysis. This research idea arises from factual case in a computer control room from a data center which is need a guarantee of operation and clock frequency maintenance. This Final project basically be a watchfulness. Intention of this final project is making a system for position livehood a node with used radio signal strength (RF) from minimum 3 node that known the position.Node hasn�t known the position stayed in field wiper RF 3 node that known their position with calculation analyticly use trilateration method. The result of distance sent and kept to master node, then sent to PC. PC will present it in 2 dimention appearance. The result of this final project declared that radio signal strength can not be used to determine position node according to 2 dimension (x and y) caused by has different value in different measurement condition. Errror measurement of distance that got up to 2.315m. Keyword : Sensor Network, 2D Position, Trilateration method
