    We present the NanoPeers architecture paradigm, a peer-to-peer network of lightweight devices, lacking all or most of the capabilities of their computer-world counterparts. We identify the problems arising when we apply current routing and searching methods to this nanoworld, and present some initial solutions, using a case study of a sensor network instance; Smart Dust. Furthermore, we propose th... View full abstract»

    Sensor networks, that consist of potentially several thousands of nodes each with sensing (heat, sound, light, magnetism, etc.) and wireless communication capabilities, provide great opportunities for monitoring spatial information about a region of interest. Although spatial query execution has been studied extensively in the context of database systems (e.g., indexing technologies), these soluti... View full abstract»

    The first generation of peer-to-peer file sharing systems followed the traditional client-server paradigm. However, legality and scalability issues have driven the development of decentralized file sharing protocols; the most popular of these being Gnutella. To date, such systems have been unable to match the quality of service (QoS) offered by centralized architectures. AGnuS improves QoS on Gnut... View full abstract»

    Peer-to-peer (p2p) networks are the latest addition to the already large distributed systems family. With a strong emphasis on self-organization, decentralization and autonomy of the participating nodes, p2p-networks tend to be more scalable, robust and adaptive than other forms of distributed systems. The much-publicized success of p2p-networks for file-sharing and cycle-sharing have resulted in ... View full abstract»

  • The deployment of cache servers in P2P networks for improved performance in content-delivery

    Publication Year: 2003, Page(s):23 - 30
    Cited by:  Papers (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (302 KB) | HTML iconHTML

    The peer-to-peer (P2P) model generally requires that bidirectional and direct communications for content-delivery be set up between user peers after discovery of the desired content; however, firewalls and the currently popular NAT/NAPT (Network Address (Port) Translation) boxes prevent most end-users from freely participating in bidirectional communications. The preferred solution to this problem... View full abstract»

    We present a token-based accounting mechanism that alleviates the free riding problem in P2P networks. The approach is complemented by distributed pricing as a flexible and viable scheme to incite users to share valuable content and to efficiently balance requests among all peers based on economic decisions.

    Service location based on greedy search is studied. A model is built to analyze the influence of the network topologies on this location method, and different network topologies are constructed to validate the model by way of simulation. The results show that, though the model assumes a uniform degree distribution, it agrees with the simulation result well if the average degree of the network is r... View full abstract»

    We describe actual and trial applications on the SIONet (semantic information-oriented network) peer-to-peer (P2P) platform developed by NTT Labs. SIONet is a logical overlay network. Peers record semantic information on SIONet routers (SI switches), which use the information to guide the routing of packets. We have already developed on-line community systems, a storage system, integrated database... View full abstract»

    E-mail is a mission-critical communication function for virtually all institutions. Modern e-mail employs a server-centric design, in which the user is critically dependent on her mail server. We present a peer-to-peer (P2P) email architecture that eliminates the need to rely on a single server and boosts the resilience of email against any kinds of attacks. Our architecture also provides confiden... View full abstract»

    It is important to enable peers to represent and update their trust in other peers in open networks for sharing files, and especially services. We propose a Bayesian network-based trust model and a method for building reputation based on recommendations in peer-to-peer networks. Since trust is multifaceted, peers need to develop differentiated trust in different aspects of other peers' capability.... View full abstract»

    Peer-to-peer (P2P) networks are self-organizing, distributed systems, with no centralized authority or infrastructure. Because of the voluntary participation, the availability of resources in a P2P system can be highly variable and unpredictable. We use ideas from game theory to study the interaction of strategic and rational peers, and propose a differential service-based incentive scheme to impr... View full abstract»

    Recently peer-to-peer networks (P2P) have gained great attention and popularity. One key challenging aspect in P2P resource sharing environments is efficient searching algorithm. This is especially important for Gnutella-like decentralized and unstructured networks since they have power-law degree distributions. A robust search algorithm should respond to the query message promptly without generat... View full abstract»

    Locating suitable resources within a peer-2-peer (P2P) system is a computationally intensive process, with no guarantee of quality and suitability of the discovered resources. An alternative approach is to categorise peers based on the services they provide, leading to the interaction between peers with common goals to form societies/communities. Organization of peers in different communities is s... View full abstract»

    The vision of the Grid is to provide a computational infrastructure supporting flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources. The Grid involves access to computer systems and data outside one's own company or institution. Security is therefore a major element in any Grid infrastructure, as it is necessary to ensure that only au... View full abstract»
