W artykule przedstawiono podstawowe założenia dotyczące realizacji systemu heterogenicznej samoorganizującej się sieci bezprzewodowej zapewniającej łączność na obszarze morskim, między innymi na potrzeby usług e-nawigacji. Wskazano na ograniczenia istniejących systemów, w tym systemów satelitarnych, pokazując jednocześnie potrzebę opracowania nowego rozwiązania. Autorzy przedstawili dedykowane mechanizmy i systemy o zróżnicowanych możliwościach transmisji danych proponowane do wykorzystywania na różnych obszarach morza. Szczególną uwagę zwrócono na praktyczne korzyści płynące z proponowanego systemu w postaci nowych możliwości wdrażania usług e-nawigacji oraz usług akwizycji i szybkiego transferu różnych typów danych.

The heterogeneous mobile terminals coexist in the next generation wireless networks. The most common routing schemes for mobile ad hoc networks are designed for homogeneous wireless networks. The heterogeneous wireless network routing protocols are needed urgently in many important applications. This paper improves the routing scheme utilizing different capability of terminals and the Hybrid Grid Routing Protocol (HGRP) is proposed. The network is organized in the grid form, that is, the network deployment area is divided into square cells according to the location. Each cell contains one backbone node and several ordinary nodes. This proposed protocol consists of four parts: grid construction, local routing, global routing, and routing correction. Analysis and simulation results indicate that the proposed protocol has the advantages of lower routing cost, lower energy consumption, smaller delay and higher throughput, compared to AODV and ZRP.

Heterogeneous wireless networks increasingly encroach on our lives. Various technologies and mobile applications more often than usual are now used by mobile users. Intensive development of mobile networks not only sets new standards for radio, but increasingly focuses on providing security for traffic transmitted in wireless networks. Security in wireless networks has never been the primary objective of the designers of new network standards. The reason for this fact were both low hardware resources of equipment, but also lack of awareness of users about the potential vulnerabilities. Creating a secure, independent of network architecture solutions effectively raising the level of security of transmitted data between end users is the main priority of our research. Current wireless security solutions do not provide sufficient protection of the integrity, confidentiality of data, are not designed to operate in heterogeneous networks, or are too complex to implement. Both networks WiMAX, LTE and WiFi, there are methods that protect the resources in these networks, but they are not consistent with each other. The proposed security system requires the use of mobile version of the PKI to verify the identity of mobile users. Mobile PKI center is an innovative solution, not yet introduced for casual use. Such a solution in heterogeneous wireless networks is a fast, secure and transparent to transmission medium. Designing secure and efficient authentication protocols to enable fast connections to the heterogeneous network is challenging. In the proposed system in this paper, the users authenticate their identity digital certificates that are issued by a trusted third party (CA). PKI uses the algorithms based on elliptic curves. Advantages of elliptic curves in mobile environment will be particularly evident. This ensures adequate protection of data in a heterogeneous networks. In this system, it is possible to implement many new secure services for end users secure email, secure chat, secure remote access.
