3Dimension Location Management for Containers

Abstract

A method to determine the 3D positions using RSSI is proposed as a solution to find location of sensors on containers. This paper presents a novel algorithm for the estimation of the coordinates and a self-correcting localization for sensors on containers. A sensor finds its location by RSSI that received from anchor (location-known) nodes or nodes which are already found. After sensors wait as much as delayed time calculated by the formula we suggested in this paper, a sensor which has the strongest RSSI broadcasts its location information and other nodes wait and save the node's location information and its procedure till finding all sensors' locations. This algorithm results in less anchor nodes and less messages. Our proposed method is simulated in our own simulator and this simulation result shows that when we use variations of signal strength with 20 % or greater, it starts to occur errors for finding a location of error. This algorithm is required of less anchor nodes and less messages.
