A mobile wireless network visualizer for assisting administrators

Abstract

As a performance index of wireless network, a heat map function for visualizing the distribution of signal strengths received from APs (Access Points) is a useful tool. Existing technologies, however, have some problems such as insufficient automation for acquiring signal information to visualize and inflexibility for dealing with on-demand monitoring requests issued by administrators on site. We propose a practical method for stably monitoring signal conditions in a managed site and efficiently visualizing the observation results. We implement the proposed method based on a light-weight publisher-subscriber communication framework applicable for various IoT applications. It can handle the on-demand monitoring requests for immediately visualizing the latest condition while it is constantly monitoring whole area as a background process. In this paper, we describe background and purpose, implementation detail, and preliminary evaluations of the proposed system.
