Title A Survey of Advanced Search in P2P Networks

Shower algorithm. When a peer gets the query it checks its routing table for any peer that could be in the range of the query and if it finds any then it forwards the query to that peer. The peer also checks if it itself is in the range or not. And if it is then it returns the dataset to the requester.

Improving Search in Peer-to-Peer Networks

When a user submits a query, her source node sends the query message to a set of its neighbors. The routing policy determines which neighbors (possibly all) are in this set. When a node receives a Query message, it may forward the query to a set of its neighbors, depending on the routing policy. The node will also process the query over its local

In contrast, structured peer-to-peer systems [35,37,44,31,26,21] provide an efficient lookup primitive that can typically locate a target within O(logN) hops. While these systems provide strong worst-case bounds, the lookup operation does not per-mit approximate matching.

Developing Trust in Large-Scale Peer-to-Peer Systems

Abstract In peer-to-peer (P2P) systems, peers often must inter-act with unknown or unfamiliar peers without the benefit of trusted third parties or authorities to mediate the inter-actions. A peer will need reputation mechanisms to incor-porate the knowledge of others to decide whether to trust another party in P2P systems. This paper discusses the de-

Query Processing in Self-Profiling Composable Peer-to-Peer

In the architecture peer-to-peer (P2P) mediators can be defined in terms of each other through object-oriented (OO) views. Query processing with scalable performance is important to make such an architecture useful in practice. The focus of the described doctoral thesis is on query processing techniques in a composable P2P mediator architecture.

Peer-to-Peer Programming Computer Science

After processing the message, the "msg c handler" function decides that it needs to send a "Query Response" message back to Peer 1, so it attempts to connect (step 6). Peer 1's main loop, listening for such connections, accepts the connection and starts its separate handler thread (step 7) to receive the actual message data from Peer 2 (step 8).

Designing a Super-Peer Network Stanford University

Abstract A super-peeris a node in a peer-to-peer network that operates both as a server to a set of clients, and as an equal in a network of super-peers. Super-peer networks strike a balance between the inherent efficiency of centralized search, and the autonomy, load balancing and robustness to attacks provided by distributed search.

Global aggregate view selection in a peer warehousing

Abstract Selecting views to materialize is one of the most important decisions to make when designing a data warehouse. In a peer data warehouse design, this problem is more difficult than in a centralized data warehouse design since the costs of global communication, data transfer, and data transformation between peers need to be additionally considered for getting the final integrated global query answers.

Top-k query processing for replicated data in mobile peer

In mobile ad hoc peer to peer (M-P2P) networks, since nodes are highly resource constrained, it is effective to retrieve data items using a top-k query, in which data items are ordered by the score of a particular attribute and the query-issuing node acquires data items with the k highest scores. However, when network partitioning occurs, the query-issuing node cannot connect to some nodes
