Agora: a semantic overlay network
Overlay networks are increasingly receiving attention as a scalable and distributed platform to realise resource discovery for file-sharing applications. However, their potential application range is much broader, as they can even serve as a communications infrastructure for distributed control and automation, e.g., underlying the electricity infrastructure. This requires the support of generic...
متن کاملA DHT-based semantic overlay network for service discovery
The number of available Internet services increases every day. This trend demands distributed models and architectures to support scalability as well as semantics to enable efficient publication and retrieval of services. Two common approaches toward this goal are semantic overlay networks (SONs) and distributed hash tables (DHTs) with semantic extensions. SONs enable semantic-driven query answ...
متن کاملA Robust Semantic Overlay Network for Microgrid Control Applications
Control systems for electrical microgrids rely ever more on heterogeneous off-the-shelf technology for hardware, software and networking among the intelligent electronic devices that are associated with dispersed energy resources. For distributed microgrid applications in a dynamic environment, overlay networks provide an opportunity for a flexible and robust logical communication infrastructur...
متن کاملPeer-to-Peer Clustering for Semantic Overlay Network Generation
The peer-to-peer (P2P) paradigm presents an attractive solution for applications that require scalability, fault-tolerance and autonomy. P2P systems in their basic unstructured form suffer high costs when it comes to efficiently locating content, mainly due to the lack of global knowledge. It is therefore crucial to organize content in an unsupervised way by creating groups of peers with simila...
متن کاملDistributed Information Retrieval Based on Hierarchical Semantic Overlay Network
One fundamental problem that confronts information retrieval is to efficiently support query with higher accuracy and less logic hops. This paper presents HSPIR (Hierarchical Semantic P2P-based Information Retrieval) that distributes document indices through the P2P network hierarchically based on documents semantics generated by Latent Semantic Indexing (LSI) [1]. HSPIR uses CAN [2] and Range ...
