This paper uses simulation studies to explore the behaviour of SCTP congestion control. Several possible variants of SCTP congestion control are identified and each is compared with the behaviour of Reno TCP, a well-known TCP variant. We identify three flaws in the current SCTP congestion control mechanisms. 1. Efficient recovery after a packet loss is only(More)
Ontologies are widely considered as the building blocks of the semantic web, and with them, comes the data interoperability issue. As ontologies are not necessarily always labelled in the same natural language, one way to achieve semantic interoperability is by means of cross-lingual ontology mapping. Translation techniques are often used as an intermediate(More)
This paper describes a semi-automated process, framework and tools for harvesting, assessing, improving and maintaining high-quality linked-data. The framework, known as DaCura 1 , provides dataset curators, who may not be knowledge engineers, with tools to collect and curate evolving linked data datasets that maintain quality over time. The framework(More)
There are emerging opportunities for distributed, composite services, based on the combination of smart homes, networked consumer devices, third-party services and social, geographical or commercial collaborations. However, current home-automation technology tends to focus on the single-home solution, rather than enabling home users can securely share and(More)
Ontologies are at the heart of knowledge management and make use of information that is not only written in English but also in many other natural languages. In order to enable knowledge discovery, sharing and reuse of these multilingual ontologies, it is necessary to support ontology mapping despite natural language barriers. This paper examines the(More)
Autonomy, adaptability, scalability, and flexible communications are all attributes of agents and multi-agent systems which suggest that they may offer timely solutions for dealing with the growing complexity of the tasks of traffic control and resource management in telecommunications networks. However, if agent-based solutions to network management(More)
Ontology-based knowledge management systems enable the automatic discovery, sharing and reuse of structured data sources on the semantic web. With the emergence of multilingual ontologies, accessing knowledge across natural language barriers has become a pressing issue for the multilingual semantic web. In this paper, a semantic-oriented cross-lingual(More)
—Regardless of which networking protocols or technologies form the core of the Future Internet it is clear that the environment as a whole will need to support a very broad range of business and user interaction modes. In todays Internet we observe the growing trend for services to be both provided and consumed by loosely coupled value networks of(More)
