Simulation tools to verify the location of nodes in wireless sensor networks

This article describes the methods and tools to verify the location of nodes in wireless sensor networks. Software product that allows to analyze the positioning based on the distance with different algorithms is proposed. As a result of simulation the next statistical output variables are defined: percentage of nodes, which have position determined; minimum, maximum and average error in assessing of nodes coordinates; the standard deviation of error. At the same time such input parameters may vary: density of nodes, the error in determining the distance, the number of nodes with known coordinates and number of nodes participating in the positioning
