“…Therefore, in addition to wires, a proposal to integrate the sensor network with other more established or to-be-established networks, such as a WiFi based mesh network, the crew/passenger network, a personnel tracking system and the global Internet was presented. Nevertheless, a later on, based on some different sources, the author of the paper [18] was stated, that although feasibility of WSN technology in ship applications can be justified from next examples from the literature (among others [16] and [19]), real deployments still meet difficulties. Although there are many networks functioning in industry, a lot of devices are still not connected to any network, because the cabling engineering is very costly.…”

“…Digital data is transmitted to PC (as a base station), so the problem of conversion of analog information into its digital representation on the entrance to PC disappears. It is worth adding that in [18] it was stated: "as we know that neither a wired nor wireless solution of deploying sensor networks on board will not work well alone to combine their strength together becomes on intuitive thought". This idea, which in fact refers to hybrid sensor networks, was implemented in [20] and [21].…”

This paper is dedicated to some aspects of maritime on-board safety improvement. The contribution of this article is a proposal to extend wireless communication on the ship, supported by examples of solutions that have not previously been used on board. Analyzed aspects concern the measurement and control signal transmission in hostile marine environment. A problem to solve is formulated, how to reduce a negative impact of this environment on effectiveness and reliability of maritime on board communication. The proposed ways for solving a problem under consideration cover recommendations concerning some aspects of ship construction and implementation of wireless sensor network. The main topic faced by the paper is concentrated on case study-based ZigBee as well as WiFi networks implementation in the area of the acquisition of data from sensors and measuring transducers connected to the terminal network. The exemplary implementation of ZigBee network, elaborated in Gdynia Maritime University is related, firstly, to the configuration of a simple wireless measurement and control channel, and secondly, to wireless communication channel supported by autonomously working microprocessor measurement and control system. WiFi networks were also tested in the same area of application. Finally, some concluding remarks are formulated.

“…For on-ship wireless sensor networks [1], [2], [3], one of the most important and desirable applications is to provide realtime location information for crews, passengers or facilities by using the sensor network as a wireless locating infrastructure. When the ships seal on the sea, the location information will be fundamental context for safety-oriented applications or onship facility management.…”

In wireless networks, radio-map based locating techniques are commonly used to cope the complex fading feature of radio signal, in which a radio-map is built by calibrating received signal strength (RSS) signatures at training locations in the offline phase. However, in severe hostile environments, such as in ship cabins where severe shadowing, blocking and multi-path fading effects are posed by ubiquitous metallic architecture, even radiomap cannot capture the dynamics of RSS. In this paper, we introduced multiple feature radio-map location method for severely noisy environments. We proposed to add low variance signature into radio map. Since the low variance signatures are generally expensive to obtain, we focus on the scenario when the low variance signatures are sparse. We studied efficient construction of multi-feature radio-map in offline phase, and proposed feasible region narrowing down and particle based algorithm for online tracking. Simulation results show the remarkably performance improvement in terms of positioning accuracy and robustness against RSS noises than the traditional radio-map method.
