The benefits of wireless sensor networks (WSN) offer many possibilities for the management of energy systems, which are actually based on wired systems. The need of new services on-board the train and of cables lengths reduction promote the use of wireless sensor networks in trains. Then, researches are required to estimate radio coverage to optimize planning before actual network deployment. In this...
The work presented in this paper is part of general study concerning the connected wagon. The objective is to ensure communications of data associated to wagon (contents, location The aim of this study is to find the most appropriate technology to design a wireless communication between wagons or between wagon and infrastructure. This analysis takes into account railway and embedded systems constraints...
In order to reduce energy consumption in buildings, sensor networks can be deployed to manage and control equipment in buildings. The WSNs based on ZigBee/IEEE 802.15.4 in the 2.4 GHz ISM (Industry Science and Medical) band, supports low prices and long battery life with moderate rates, low complexity of deployement, and simple data connectivity. The aim of this work is the study and analysis of the...
To deploy Wireless Sensor Networks (WSNs) in the railway transport, knowledge of signal propagation in this environment is required for the safety and the reliability of whole system. This calls to two domains of research. Firstly, the study of the propagation characteristics is necessary to predict the propagation law that rules attenuation of the signal in the train environment along with the multipath...
