ABSTRACT
Wireless communications in industrial environments are seriously affected by reliability and performance issues, due to the multipath nature of obstacles within such environments. Special attention needs to be given to planning a wireless industrial network, so as to find the optimum spatial position for each of the nodes within the network, and especially for key nodes such as gateways or cluster heads. The aim of this paper is to present a pervasive radio mapping system which captures (senses) data regarding the radio spectrum, using low-cost wireless sensor nodes. This data is the input of radio mapping algorithms that generate electromagnetic propagation profiles. Such profiles are used for identifying obstacles within the environment and optimum propagation pathways. With the purpose of further optimizing the radio planning process, the authors propose a novel human-network interaction (HNI) paradigm that uses 3D virtual environments in order to display the radio maps in a natural, easy-to-perceive manner. The results of this approach illustrate its added value to the field of radio resource planning of industrial communication systems.

Mentions: Regarding the performance of the algorithm for detecting optimum propagation pathways, in the case of industrial hall A, out of the 112 areas which are potentially suitable for radio propagation (192 − 80 = 112 squares in the grid) an average of 83.9% were successfully detected (Figure 14). For the 2nd industrial hall considered in the experiments, out of the 128 areas that are free of obstacles, an average of 80.9% were successfully detected.
