— Due to the increasing deployment of conversational real-time applications like VoIP and videoconferencing, the In-ternet is today facing new challenges. Low end-to-end delay is a vital QoS requirement for these applications, and the best effort Internet architecture does not support this natively. The delay and packet loss statistics are directly coupled(More)
Musical collaboration over telecommunication networks has marvellous possibilities when it comes to musical education, practise and performance. The deployment and use of high-capacity digital networks makes it possible to obtain end-to-end audio and video latency of 5−20 milliseconds, which is similar to the audio time delay typically experienced between(More)
Routing for low latency underwater acoustic network-communication is investigated. The application is monitoring of ice-threats to offshore operations in the Arctic-to provide warnings that enable operators to react to such threats. The scenario produces relatively high traffic load, and the network should favour low delay and adequate reliability rather(More)
Ubiquitous and IoT (Internet of Things) systems consist of many parts, are highly distributed and need to be adaptive in a highly dynamic environment. The exploitation of adaptation possibilities at different layers needs to be coordinated to get an optimal result. However, it is difficult to test and evaluate such distributed systems with regard to their(More)
(Active Queue Management) enabled router. The design is based on a classical proportional control system. The application of such a router is to enhance streaming media over IP performance by avoiding bursty packet drop situations, control the router queue delay, and balancing packet drop, delay, and link utilization. The selected AQM equilibrium point(More)
The integration of communication and computation technologies, the availability of pocket mobile computers, and the widespread penetration of mobile radio access networks will enable a range of new context-aware mobile services to be offered to the users. Research on methods and technologies for the development of such services requires the involvement of(More)
