In this paper, we present GeoCast, a geographical location aware overlay network framework designed for providing efficient group communication services. GeoCast can be seen as an extension to the CAN network in the term of topology management and routing protocol. Geocast design has three important properties that attractive to group communication applications. First, it uses geographical mapp...

The survey and classification of the different security attacks in structured peer-to-peer (P2P) overlay networks can be useful to computer system designers, programmers, administrators, and users. In this paper, we attempt to provide a taxonomy of structured P2P overlay networks security attacks. We have specially focused on the way these attacks can arise at each level of the network. Moreove...

Peer-to-peer systems and applications are distributed systems without any centralized control. The core operation in most peer-to-peer systems is efficient location of data items. The current well-known peer-topeer systems like Napster and Gnutella have scalability problem in location of data items. To solve the scalability problem, some scalable peer-to-peer lookup services show up, such as CA...

This paper is an attempt to quantify the performance differences for content-based multicast implemented inside the overlay routing algorithm or built on top of the simple API provided by the routing layer. We focus on overlay networks designed for peer-to-peer distributed hash table (DHT) applications where content-based multicast is most applicable. In particular we study the Content Addressa...

XGR (XML Data Grid) and BabelPeers are both data management systems based on distributed hash tables (DHT) that use the Pastry DHT to store data and meta data. XGR is based on the XML data model; BabelPeers uses the Resource Description Framework (RDF) for its data. XGR and BabelPeers have different but complementary functionality. On the one hand, XGR focuses on document-based storage of XML d...

Increasing mass-market acceptance of on-demand streaming services motivates us to seek new innovations in the way we deliver media content over networks. An architecture is proposed in which edge-resources in a peer-to-peer network assist in the provision of fullyinteractive on-demand streaming services based on multicast. This approach represents a synergy between multicast batching, proxy pre...

Distributed service architectures are mandatory to handle the platform scale and dynamicity hindering the development of grid and P2P applications. These large-scaled distributed applications are difficult to design, develop and tune because of both theoretical and practical issues. This paper presents the GRAS framework that allows developers to first implement and experiment with such an infr...

In this paper we present a scalable distributed ontology storage system (OntStore), which unlike other ontology repositories is capable of storing and querying the ontologies and the resource descriptions in a distributed manner. It is based on the distributed hash table (DHT) approach emerging in the P2P arena and well known W3C standardized languages. The system decomposes the ontologies into...

The aim of this deliverable is to present the validation results of the architecture, protocols and services designed for the MobileMAN project. This deliverable therefore represents the complement of Deliverable D13. Specifically, D13 presents the MobileMAN architecture and protocols, while in this deliverable the solutions we devised are validated. Whenever possible, our evaluations are based...

This study aimed to explore the role of home industry activities for community in Tilongkabila district. was qualitative research with a case method. examined depth economic empowerment through industries that have developed Bongopini Village (Tofu Tempeh), Lonuo (Chips and Sugar Brown), Permata Bongoime (Cake, Pia, workshop, Ayam Geprek Restaurant), Tamboo (pastry). Furthermore, data were coll...
