Peer-to-Peer (P2P) networking is beneficial when removing a centralized server. On the other hand, new mechanisms are required to compensate for the central authority, especially for network security and dependability. In this paper, we propose a new fuzzy reputation (Fuzzy-Rep) model to improve security and dependability of P2P e-commerce. The model employs fuzzy logic inference rules to assess transactions...
Efficient resource search in large-scale unstructured peer-to-peer (P2P) systems remains a fundamental challenge. In order to improve search performance, interest-based search is a good way to tackle the challenge. However, the existing interest-based search algorithms pay attention to user interest model and search history, but ignore some influence factors of improving performance. In this paper,...
For the provision of dependable search and rescue capability in dynamic and unpredictable disaster areas, each networked node should have ability to (1) autonomously support and co-operate with each other in a peer-to-peer (P2P) manner to quickly discover and dependably self-configure services available on the disaster area to deliver a real-time capability; (2) modify their behaviours to deliver...
For provision of dependable search and rescue capability in dynamic and unpredictable disaster areas, the networked nodes should have the ability to autonomously support and co-operate with each other in a peer-to-peer (P2P) manner to quickly configure any services available on the disaster area to deliver a real-time capability. In this paper, we present an innovative architectural approach which...
In social networks, people can directly contact some acquaintances that potentially have knowledge about the resources they are looking for. Similarly to social networks, where people are connected by their social relationships, two autonomous peer nodes can be connected in unstructured peer-to-peer (P2P) networks if users in those nodes are interested in each other's data. The similarity between...
SIG (spatial information grid) is a spatial information infrastructure which has the ability of demand serving, also it is a mass spatial information resource which could collect and share geographic distribution data. However, currently, many problems are exited in the spatial information resource locating method of SIG, they are especially the excessive net bandwidths it takes, overlong resource...
Peer-to-peer (P2P) networks attract attentions worldwide with their great success in file sharing networks (e.g. Napster, Gnutella, BitTorrent, and Kazaa). In the last decade, numerous studies have been devoted to the problem of resource discovery in P2P networks. However, efficient resource discovery remains a key challenge for large-scale P2P networks. An investigation of existing research on resource...
