Peertopeer networking is a disruptive technology for large scale distributed app cations that has recently gained wide interest due to the successes of peertopeer (P2P) content sharing, media streaming, and telephony applications. There are a large range of other applications under development
The main contributions of ETop are threefold. First, it proposes two economic incentive schemes, namely ETK and ETK+, in which peers act individually towards topk query processing. Second, it extends ETK and ETK+ to propose a peer groupbased economic incentive scheme ETG.
To address this drawback, we push query processing to the client side and demote the server's responsibility to a central storage and retrieval module for our encrypted indexes. (a) (b) (c) (d) Fig. client side query processing imposes certain restrictions on the choice of .

proposed peertopeer location anonymization technique uses the privacypreserving query pro cessing framework designed for the trusted third party architecture. After a user finds a cloaked area as her location, she randomly selects a peer within the cloaked area as an agent.
AbstractA peertopeer collaboration framework for multi sensor data fusion in resourcerich radar networks is presented. In the multisensor data fusion, data needs to be combined in such a manner that the realtime requirement of the sensor application is met.
Abstract. This work addresses the processing of topk queries in mobile ad hoc peer to peer (MP2P) networks using economic proposed economic model, designated as EcoTop, issues economic rewards to the mobile peers, which send relevant data items (, those that contribute to the topk query result), and penalizes peers for sending irrelevant items, thereby incentivizing the ...

distinguishes a peertopeer search network from a distributed hash table [19, 16], where the queries are to locate a specific document with a specific identifier (see Section 7 .
On internet peer to peer networks utilize 70 percent of bandwidth and lot of load comes from query processing. As database is accessed to download and upload documents, media files, software applications there is need for efficient query processing methods.
One of the most challenging problems in peertopeer networks is query routing: effectively and efficiently identifying peers that can return highquality local results for a given query. Existing methods from the areas of distributed information retrieval and metasearch engines do not adequately address the peculiarities of a peertopeer ...
The concurrent execution of multiple and often identical distributed aggregate queries can place a high burden on the data sources. This paper identifies the scalability bottlenecks that can arise in large peertopeer networks from the execution of large numbers of aggregate computations and proposes a .
