The objective of this paper is to characterize the electromagnetic waves propagation between adjacent decks on board a ship. First, narrowband measurements were conducted at 2.45 GHz to study the radio coverage. Different configuration scenarios where considered. Then, double directional channel sounding was performed at 3.5 GHz to determine the propagation mechanisms and multipath parameters in this...
Wireless Sensor Networks (WSN) have recently gained a great attention in several applications such as environmental monitoring and target tracking. Applying this technology to shipboard monitoring systems may be a cost-effective solution to reduce the cost of wires installation and maintenance. However, wireless communications on board ships may be severely obstructed by the metallic structure of...
Wireless Sensor Networks (WSN) may be a very useful technology for monitoring systems in hostile environments. Few works have treated the use of this technology in the particular metallic shipboard environment. This paper reports on the deployment of a WSN on board a ferry-type boat during realistic conditions. The network was tested during sailings and stopovers for several days. The results of our...
Wireless Sensor Networks (WSNs) have been used recently in different applications such as environmental monitoring and target tracking. Few papers have investigated the viability of this technology on board ships. We study in this paper the possibility of replacing the wired shipboard monitoring system by a WSN. This environment has a specific metallic structure which makes the wireless communication...
The objective of this reported work was to characterise electromagnetic wave propagation between adjacent rooms in the lower deck areas of ships. A wideband multiple-input multiple-output channel sounder has been used to realise double directional propagation measurements at 2.2 GHz. The antenna configuration was a linear array at the transmission side and a rectangular one at the reception. The measurement...
This paper studies the feasibility of ubiquitous wireless technologies for shipboard monitoring systems. A measurement campaign has been conducted aboard a ferry boat to study the propagation challenges of wireless communication in this harsh environment. Path loss models have been obtained from the measurements results. We have used these results to determine engineering rules concerning the nodes...
This paper presents measured data and empirical models for 2.4 GHz radio propagation path loss aboard ships. The first experiment was conducted aboard a ferry moored to the port, while the second one was carried out aboard another ferry during its cruises between Roscoff (France) and Plymouth (UK). Three different shipboard environments, including engine rooms, parking and passengers' decks, were...
