Quality Analysis of Data Transferring Through the Process of Modeling WirelessHART Network

Abstract

The topology of WirelessHART network is changeable since a number of dynamic devices change, and all that requires a
reorganization of the network, as well as finding new ways of routing data. Devices can fall out of the network due to destruction,
failure, reduction or loss of electricity. On the other hand, it is possible to “refresh” the network with new devices and thus completely
change the topology of the newly created network. This research analize the quality of data transferring in a WirelessHART network
using two network topologies: Extended star network and Mesh network. The aim of this paper is to determine which network topology
provides better quality of data transferring in a WirelessHART network on the basis of signal latency and Received Signal Strength
Indicator (RSSI). To achieve this, experiments are performed using the equipment by the manufacturer Emerson Process Management:
Gateway 1420, TT 648 and PT 3051 for the implementation of the network, as well as software tools for configuration, planning and
management of wireless industrial networks, AMS Wireless SNAP-ON and AMS Intelligent Device Manager. The research results show
several advantages of applying Mesh topology in a WirelessHART network: it is almost impossible to interrupt communication between
devices in the network; there does not have to be optical visibility between the network devices; ease of installation and deinstallation;
low application cost compared to Extended star network.
