Abstract

A visualization tool for displays devices included within a self-organizing mesh network with respect to the physical space occupied by the network. The visualization tool receives an image representing the physical space occupied by the wireless mesh network, scale information defining the scale of the received image, and location information defining the location of each device within the physical space occupied by the network. Based on these inputs, the visualization tool displays the layout of the wireless mesh network with respect to the physical space occupied by the wireless mesh network.
