“…Moreover, lack of measurements in Wi-Fi plot in this area indicates a loss of connectivity for this technology in the case ofmore resilient NV2 the same conditions were sufficient to maintain a link. When analyzing the above results we need to remember, thatin the case of WLAN technologies link activation requires a number of higher level procedures to be completed, such as searching for available networks, network selection based on number of criteria (e.g., network name, supported security mechanisms), authentication, association and dissemination of cryptographic keys [71]. Each of the procedures requires a successful exchange of messages between communicating devices.…”

As the number of research activities and practical deployments of unmanned vehicles has shown a rapid growth, topics related to their communication with operator and external infrastructure became of high importance. As a result a trend of employing IP communication for this purpose is emerging and can be expected to bring significant advantages. However, its employment can be expected to be most effective using broadband communication technologies such as Wireless Local Area Networks (WLANs). To verify the effectiveness of such an approach in a specific case of surface unmanned vehicles, the paper includes an overview of IP-based MAVLink communication advantages and requirements, followed by a laboratory and field-experiment study of selected WLAN technologies, compared to popular narrowband communication solutions. The conclusions confirm the general applicability of IP/WLAN communication for surface unmanned vehicles, providing an overview of their advantages and pointing out deployment requirements.

“…Moreover, such mobility mechanisms are at best applicable only in the case of homogeneous networks and address only the link layer [21] mobility issues. As such, they are not sufficient to address Internet mobility across heterogeneous networks.…”

“…Mobility in 802.11 means change of physical access point when the MN moves between access points in the extended service set (ESS) infrastructure. The whole handover (handoff) procedure is composed of a number of phases [21], among which detection, scanning and IEEE 802.1x authentication are operations that consume the most time (see Table 2). Minimization of scanning time (Tscan) can be achieved by employing one of the algorithms proposed in literature (see e.g., [22]).…”

Enormous progress in the design of portable electronic devices allowed them to reach a utility level comparable to desktop computers, while still retaining their mobility advantage. At the same time new multimedia services and applications are available for IP users. Unfortunately, the performance of base IP protocol is not satisfactory in mobile environments, due to lack of handover support and higher layer mobility management mechanisms. In this paper, we outline the most important current methods of handling mobility in IP networks that are expected to play an important role in the future (covering the following ISO-OSI layers: 2+, 3, 3+, 4 and 7 of mobility solutions), as well as describe the newly proposed methods.

“…The process is not a straightforward one even in within a homogenous system under consolidated management, and it only gets more difficult when we need to perform it across administrative network boundaries or between two different access technologies. Due to the task complexity and many different scenarios which contribute to its necessity, taxonomy of handover types and solutions is an extensive one [39], which makes it impractical to include in this paper. Instead, a review of some general areas for process optimizations and a few chosen approaches to the problem in example environment of the most popular WLAN technologies are presented.…”

With popularization of mobile computing and diverse offer of mobile devices providing functionality comparable to personal computers, the necessity of providing network access for such users cannot be disputed. The requirement is further reinforced by emergence of general purpose mobile operating systems which provide their full functionality only with network connectivity available and popular XaaS (Everything as a Service) approach. In this situation and combined with the fact that most Internet-based services are able to function efficiently even in best effort environment, requirement of ubiquity of network access becomes one of the most important elements of today’s computing environment. This paper presents a general overview of the the vast group of mechanisms and technologies utilized in modern attempts to efficiently provide ubiquity on network access in heterogeneous environment of today’s access systems. It starts with division of users interested in ubiquitous network access into broad groups of common interest, complete with their basic requirements and access characteristics, followed by a survey of both already popular and new wireless technologies suitable to provide such access. Then a general discussion of most important challenges which must be addressed while attempting to fulfill the above goal is provided, addressing topics such as handover control and mobility management.
