Accurate distance estimation is crucial for ensuring the safety and efficiency of intelligent and future autonomous mobility. In this paper, we propose a method for real-time estimation of visible lane distance based on image data only from a single camera and an existing road lane marking estimation system. By leveraging camera intrinsics and heig...

This scholarly discourse presents a novel architecture for automating student assignment evaluations leveraging the Docker environment. The innovative design promotes individualized technology selection by students for problem-solving in academic assignments. The assessment of these assignments relies on the utilization of RESTful APIs encapsulated...

WiFi networks have become the most used technology when connecting various personal devices to the Internet at home, in the office, or even in public places. Such popularity and widespread use make WiFi networks an attractive target for attackers. Despite the encryption of network frames and other security features implemented as part of the IEEE 8...

Smart contracts belong to the most rapidly growing aspect of the world of cryptocurrencies. This phenomenon attracts great attention from researchers but also the business community, and the development brings daily a lot of novel applications. Smart contracts allow running contract code transparently for all parties, without the need for a central...

Featured Application This paper presents a solution of a TCP session handoff mechanism using Software Defined Networking, which can be used as a transparent redirection mechanism in Content Delivery Networks. Abstract In today’s age of digital media and social networks, delivering content to a massive scale of recipients became one of the main cha...

Some forms of voting have been here ever since. Mostly used form all over the world are paper ballots. Electronic voting schemes are being popular only in the last decade and they are still unsolved. E-voting schemes bring problems mainly regarding security, credibility, transparency, reliability, and functionality. Estonia is the pioneer in this f...

Merging Software-Defined Networking (SDN) and Wi-Fi networks to Software-Defined Wireless Networking (SDWN) more often appears in scientific papers lately. However, none of the proposed architectures allow securing the wireless part of the network. In this paper, we are introducing specialized EnDeC component, which can encrypt and decrypt wireless...

The car-sharing market is constantly growing and recently it has become even more popular than car ownership. However, classic car-sharing system is based on a centralized database server which can often lead to hacker attacks or password leaks. Moreover, in a classic car-sharing system, the owners of the cars can misuse customers' data. As seen no...

Wireless Local Area Network (WLAN) infrastructure is a dominant technology for direct access to the Internet and for cellular mobile data traffic offloading to WLANs. Additionally, the enterprise infrastructure can be used to provide functionality for the Internet of Things and Machine to Machine scenarios. This work is focused on improvements of r...

This article focuses on mobility of stations under 802.11 standards, with use of Software-Defined Networking (SDN). Lately, there are several SDN-based solutions for seamless handover. These solutions typically use separate control channels to utilize the wireless part of network. In our work, we demonstrate high performance of SDN WLAN architectur...

This article is focused on the area of client mobility in Software-Defined Networking (SDN) for 802.11 standards. Recently, there are a few SDN solutions how to perform smooth and fast handover. Usually these solutions are using separated control channel for control 802.11 functionality. In our work, we demonstrate efficiency of common control chan...

TV watching dramatically changes with introduction of new technologies such as Internet-connected TVs, enriched digital broadcasting (DVB), on-demand content, additional programme information, mobile phones and tablets enabling multiscreen functions etc that offer added values to content consumers. In this paper we propose modular advanced TV platf...

The duration of handover in WiFi - 802.11 network is a limiting factor for multimedia applications. We propose a novel approach that rapidly decreases handover time, while leaving the current functionality of mobile stations unchanged. The proposal is based on a Remote MAC separator design and creates new network architecture taking into account cl...
