Peertopeer systems have emerged as a popular way to share huge volumes of data. The usability of these systems depends on effective techniques to find and retrieve data; however current techniques used in existing P2P systems are often very inefficient. We present three techniques for efficient search in P2P systems. We present the design of these techniques, and then evaluate them using a ...
We propose Secure Data Aggregation for Multiple Queries (SDAMQ) in Wireless Sensor Networks where multiple aggregate queries from the sink are authenticated and distributed to the sensor nodes. The sensor nodes respond by aggregating data belonging to multiple coexisting queries into a single packet, there by reducing the transmission cost.
FIG. 8 is a flowchart 800 of an embodiment of processing performed by a control server in a peertopeer network for facilitating delivery of streaming content in a peertopeer network. A client connects with the control server (step 802 ) and submits a request for a list of peers (step 804 ).
One of the main challenges in sensor networks is to process and aggregate data in the network rather than wasting energy by sending large amounts of raw data to reply to a query. Some efficient ... The widespread deployment of sensor networks is on the horizon.
We offer degrees in electrical engineering, computer science, computer engineering and data science and graduate degrees (master's degrees and 's) in electrical engineering and computer science and engineering. EECS focuses on the convergence of technologies and disciplines to .
data exchanged among nodes during query processing. We study this problem in a peertopeer sensor network where all sensor nodes have similar capabilities, sensed measurements are stored locally, each sensor is only aware of the existence of the other sensors located within its wireless communication
A transaction request sent from a client or admin user to one or more peers in a network; examples include deploy, invoke, query, or configuration request. Deploy Refers to the function through which chaincode applications are deployed on chain .
The Internet community has recently become interested in distributed query processing. Not sur prisingly, they approach this problem from a very different angle than the traditional database literature. The fundamental goal of Internet systems is to operate .
Many emerging applications that use XML are distributed, usually over large peertopeer (P2P) networks on the Internet. The deployment of an XML query shipping system over P2P networks requires a specialized synopsis to capture XML data in routing tables. In this paper, we propose a novel graphstructured routing synopsis,
Then, the query processing will be similar to the one used in the trusted third party architecture. (b) Providing an innetwork location anonymization algorithm that is suitable for both indoor or outdoor environments regardless of the system's physical structure [3]. The main idea is to let sensor nodes provide aggregate infor
In recent years, the data management community has begun to consider situations in which data access is closely tied to network routing and distributed acquisition: examples include, sensor networks that execute queries about reachable nodes or contiguous regions, declarative networks that maintain information about shortest paths and reachable endpoints, and distributed and peertopeer ...

I'm using kettle which support the aggregation pipleline in MongoDB when using MongoDB input the query works for small data set but I need to use option allowDiskUse to the query can't figure how to add this in pentaho while I tested this option in mongo shell and it's working as expected

Dynamic querying (DQ) is a search technique used in unstructured peertopeer (P2P) networks to minimize the number of nodes that is necessary to visit to reach the desired number of results.
(7) Decentralized Search in PeertoPeer Networks Recently, decentralized search has been applied to the problem of sharing files in a peertopeer network without a global index. Each host in the system holds a subset of the content, and requests must be routed to .

tributed, usually over large peertopeer (P2P) networks on the Internet. The deployment of an XML query shipping system over P2P networks requires a specialized synopsis to capture XML data in routing tables. In this paper, we propose a novel eigenvaluebased routing synopsis for deployment over unstructured P2P networks.
In one embodiment, the first peer node transcodes the data before transmitting the data to the second peer node, wherein the transcoding includes converting the data into a format that can be processed by the second peer node, and transmitting the data to the second peer node in a transport specification as requested by the second peer node.
Abstract. Peertopeer (P2P) file sharing system provides a platform that enables users to share their files over network and provides a rapid and scalable content distribution mechanism to access an explosive volume of shared files on the system. The search mechanism in .
