The emergence of Peer-to-Peer (P2P) computing model and the popularity of Extensible Markup Language (XML) as the web data format have fueled the extensive research on retrieving XML data in P2P networks. In this paper, we developed an efficient and effective keyword search framework that can support tag-term keyword queries in Distributed Hash Table (DHT) networks. We employed a concise Bloom-...

Peer-to-Peer (P2P) systems are application layer networks which enable networked hosts to share resources in a distributed manner. An important problem in such networks is to be able to efficiently search the contents of other peers. In this paper we present a survey of search techniques for information retrieval in P2P networks, including recent techniques proposed by the authors. We also pres...

The exponential increase of availability of digital data and the necessity to process it in business and scientific fields has literally forced upon us the need to analyze and mine useful knowledge from it. Traditionally data mining has used a data warehousing model of gathering all data into a central site, and then running an algorithm upon that data. Such a centralized approach is fundamenta...

Recently, exploring effective ways for distributed resources that allow sharing large amounts of data among users are presenting new challenges to computer networks. The Peer-to-Peer (P2P) networks have emerged over the past several years as new and effective ways for distributed resources to communicate and cooperate security and privacy in a number of ways. This paper focused on a new platfor...

Energy communities have been designed to empower consumers while maximizing the self-consumption of local renewable energy sources (RESs). Their presence in distribution systems can result strong modifications operation and management such systems, moving from a centralized distributed one. In this scope, work proposes community-based market that aims at minimizing costs each community member, ...

Peer-to-Peer (P2P) systems provide a new solution to distributed information and resource sharing because of its outstanding properties in decentralisation, dynamics, flexibility, autonomy and cooperation, summarised as DDFAC in this paper. After a detailed analysis of the current P2P literature, this paper suggests to better exploit peer social relationships and peer autonomy in order to achie...

Databases and Grid computing are a good match. With the service orientation of Grid computing, the complexity of maintaining and integrating databases can be kept away from the actual users. Data access and integration is performed via services, which also allow to employ an access control. While it is our perception that many proposed Grid applications rely on a centralized and static infrastr...

With the extending of spatial information system into the distributed network environment, it faces some challenges including the mass data character of the spatial data, the limited band width of current network, the devilishly centralized spatial information management and geographic computing resources, as well as the higher requirements of the spatial information service capability. For ove...

Epidemic protocols proved to be very efficient solutions for supporting dynamic and complex information diffusion in highly distributed computing infrastructures, like P2P environments. They are useful bricks for building and maintaining virtual network topologies, in the form of overlay networks as well as to support pervasive diffusion of information when it is injected into the network. This...
