“…There is almost no obstacle in the sea, and the sea surface is also flat. These factors actually cause a huge path loss, due to negative interference between the line of sight (LoS) path and the reflected path [2].…”

“…Nowadays, communication systems based on narrow ultra-high frequency band (UHF, 300MHz-3GHz) and very high frequency band (VHF, 30-300MHz) are used for close water ports' ship-to-shore communication. On the other hand, satellite communication is used for long range ship-to-shore and ship-to-ship communication [2]. Satellite links are very expensive for voice calls and Internet access, to and from the ship, when compared to land communication.…”

Maritime cognitive radio networks (MCRNs) have recently been proposed for opportunistic utilization of the licensed band. Spectrum sensing is one of the key issues for the successful deployment of the MCRNs. The maritime environment is unique in terms of radio wave propagation over water, surface reflection and wave occlusions. In order to deal with the challenging maritime environment, we proposed an optimal entropy-based cooperative spectrum sensing. As the results of spectrum sensing are sensitive to the number of samples in an entropy-based local detection scheme, we first calculated the optimal number of samples. Next, a cooperative spectrum sensing scheme considering the conditions of the sea environment is proposed. Finally, the throughput optimization of the m-out-of-n rule is considered. Results revealed that although the existing schemes work well for the lower sea states, they fail to perform at higher sea states. Moreover, simulation results also indicated the robustness of the entropy-based scheme and the proposed cooperative spectrum sensing scheme at higher sea states in comparison with the traditional energy detector.

“…However, due to the fact that FM radio transmission has a low data-rate characteristic and satellite communication is quite expensive, considerable effort has been devoted to the development of new maritime wireless communication technologies and cheaper satellite services. Maritime mobile WiMAX networks have drawn much attention [2]. Furthermore, advances in antenna technology and satellite coverage have combined to make VSAT Ku Band satellite services very attractive, as they can provide higher data-rate transmission, good Quality of Service, compatibility with IP networks and flat-rate charging.…”

Abstract. The rapid evolution of terrestrial wireless systems has brought mobile users more and more desired communication services. Maritime customers are asking for the same, such as the concepts of "Broadband at Sea" and "Maritime Internet". Quite a lot of research work has focused on the development of new and better maritime communication technologies, but less attention has been paid on interworking of multiple maritime wireless networks or on satisfying service provisioning. To address this, an integrated wireless Communication Architecture for Maritime Sector (CAMS) has been introduced in this article. CAMS is aimed at 1) granting maritime customers uninterrupted connectivity through the best available network and 2) providing them with the bestprovisioned communication services in terms of mobility, security and Quality of Experience (QoE). To address mobility challenge, the IEEE 802.21 standard is recommended to be used in CAMS in order to achieve seamless handover. CAMS provides application-level QoE support attending to the limited communication resources (e.g. bandwidth) at sea. Certain security considerations have also been proposed to supplement this architecture.

“…We illustrate our new approach with Triton [10], a proposed 802.16-based (WiMax) maritime wireless access mesh network consisting of large ships traveling in the Straits of Singapore or anchored by the Singapore harbour. Currently, ships have limited high-speed access to land-based data, such as access to databases, navigation information, and the Internet.…”

We present an approach for developing routing algorithms where we first attempt to understand the network characteristics (i.e. network connectivity, mobility and rate of change of the topology) and expected traffic patterns of a specified mobile scenario before proceeding to design an algorithm that optimizing routing performance for the common cases. We apply our approach to Triton, a proposed 802.16-based (WiMax) maritime wireless access mesh network. Our trace-based analysis shows that in our environment, if stationary nodes are preferred in the route selection, the rate of change for the routes to the gateway nodes is reduced by 23.3% and the average duration for which routes between a node and a gateway remains valid is increased by 31%. We also show that it is important to take the expected traffic patterns into account when designing routing for a specific system. By ignoring changes to the network topology that do not affect the anticipated traffic, we can significantly reduce the overheads associated with the repair of the routing tables.
