Since mobile terminals such as smartphones are basic information tools for users, their communication performance is always significant. Modern loss-based Transmission Control Protocols (TCP) take aggressive congestion window (CWND) control strategies in order to gain better throughput, but such strategies may cause a large number of packets to be backlogged and eventually dropped at the entry point...
The Internet of Things and big data provided by sensors and users, combined with mobile connections, enable various solutions and applications used for vehicles and traffic. Sensor data, as well as other data from the networks, can be transferred to the driver using existing technologies. With the help of this data, the driver can make driving and safety decisions. However, transferring data to and...
Manufacturing systems' digital transformations increase the vulnerability of industrial systems. Cyber security is a continuous cat-and-mouse game. Vulnerabilities are found and fixed, but hackers are usually one step ahead. Cyber security resonates at all levels of society, and the Internet of Things is bringing new threats in this area. Security investments increase while technology development...
Increasing amount of applications for vehicular networks has been recently proposed. Many of them aim to help people to drive more economically and safely. Especially safety related applications require high quality connections for both vehicle-to-vehicle and vehicle-to-infrastructure communications. Currently, ITS-G5 (IEEE 802.11p) can be considered as the most mature standard for vehicular networks...
This paper describes Centria's research work on improving traffic safety and traffic flow by developing mobile applications to support real-time decision making. Centria has utilized a wide range of mobile device built-in capabilities in the mobile applications it has developed. For example, Wi-Fi has been used for vehicular area networking, 3G/4G/LTE for vehicle-to-infrastructure (V2I) communication,...
In this demonstration paper, we will present our adaptive user interface for replacing a vehicle's conventional dashboard. A programmable tablet computer with the Android operating system was utilized for displaying a vehicle's conventional instrumentation data and navigation guidance, as well as notifications from the vehicle's local safety sensors or external infrastructure. The developed user interface...
In this demonstration paper we will present our advance car navigation application which has been designed for Unity game engine with point cloud spatial data. Our demonstration will show how three dimensional spatial data can be used in game engines as a basis of traffic data visualization. The designed cognitive navigation application has been developed in a close cooperation between two Finnish...
In this paper, the design and development of wireless sensor and actuator networks that enable Internet-of-Things (IoT) solutions are investigated from the perspective of cognitive infocommunications. The reasons, requirements, and issues related to adaptive systems and architectures are presented, and the corresponding intra-cognitive and inter-cognitive communications are examined. The current and...
Cognitive infocommunication plays a key role in intelligent traffic systems. Situational awareness and information delivery are key factors that support a driver in making correct decisions in everyday driving conditions. When a driver does not feel relaxed or comfortable, these factors are even more crucial. This paper introduces Centria University's research work on this important topic of how to...
Cognitive Infocommunications (CogInfoCom) studies the connections between infocommunications and cognitive experiences. This paper presents a practical performance evaluation of an active antenna system (AAS) based on tests performed in a field trial environment with a cellular high-speed packet access (HSPA) network. Cellular networks face the challenges of constantly growing data traffic and demands...
Inter-cognitive communication plays the key role in the development of engineering applications where natural and artificial cognitive systems should work together efficiently. Situation-awareness is essential in that cooperation. The focus of this study is to report our experiences and applications of situation-aware robots and transporters. Industrial robots are an important part of production in...
