When a client wishes to submit a query to the network, it will send the query to its superpeer only. The superpeer will then submit the query to its neighbors as if it were its own query, and forward any Response messages it receives back to the client.

Peertopeer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the application. They are said to form a peertopeer network of nodes. Peers make a portion of their resources, such as processing power, disk storage or network bandwidth, directly available to other ...

Impact of Applying Aggregate Query Processing in Mobile Commerce: /: With the increased usage of mobile devices, society is seeing more and more users doing transactions wirelessly. Often, data from a single server may not be
The pace of research on peertopeer (P2P) networking in the last five years warrants a critical survey. P2P has the makings of a disruptive technology it can aggregate enormous storage and processing resources while minimizing entry and scaling costs. The key to

We then retrieve certain information from the visited peers, such as the number of tuples, the aggregate of tuples (for example, SUM, COUNT, AVG, and so forth) that satisfy the selection condition, and send this information back to the query node

Two Phases of Approximate Query Processing (AQP) 1. Offline preprocessing of the database. generate histograms or random samples. OK to use considerable space and time (hours) 2. Runtime query processing. Query answers must be fast (seconds) Only time to access small amount of data. extrapolate from random sample. Small Group Sampling
network, nodes spend processing resources (, cycles) to forward the query, process it, etc, and bandwidth to send and receive messages. The main cost of queries are therefore bandwidth and processing. Since the cost of a query is not incurred at any single node in the network, it makes sense to discuss costs in aggregate (, overall the nodesin
This paper characterizes the query behavior of peers in a peertopeer (P2P) file sharing system. In contrast to previous work, which provides various aggregate workload statistics, we characterize peer behavior in a form that can be used for constructing representative synthetic workloads for evaluating new P2P system designs. In
PeertoPeer systems, Searching, Caching, Data structures TECHNICAL AREAS PeertoPeer Systems, Data Management, Operating Systems and Middleware I. INTRODUCTION This paper addresses the problem of multiattribute search in peertopeer (P2P) networks. We use indices of searchable attributes to permit such searches without ooding the network.
Extensive application of PeertoPeer systems demands an effective solution for efficient query processing, handling of churn rate, load balancing and maintenance of healthy arrangement of nodes for the improved response of the system. Several key based systems offer an efficient solution for query processing but suffer
