Peer-to-peer (P2P) network is increasingly becoming popular because it offers opportunities for real-time communication, ad-hoc collaboration and information sharing in a large-scale distributed environment. Peer-to-peer computing is defined as the sharing of computer resources and information
query processing has gained more and more attentionrecently because of its wide use in many fields, such as information retrieval, multimedia databases, P2P and sensor networks
query processing unavoidably involves energy-wise costly communication among nodes, it imposes hard constraints on their lifetime. Therefore, energy-eﬃcient query processing techniques are of utmost important within a sensor network, and that is the very focus of this paper.
Aggregates the ratings of only a few peers Can't get a wide view about a peer's reputation Aggregates the ratings of all the peers Congesting the network with system messages asking for each peer's local trust values at every query Global Trust Value The overall estimation of, for each peer j How to calculate these global trust values?
This query is dropped at peer 3 as a duplicate query. Hence, the presence of short-cuts in the overlay network may harm the performance of the system in two ways.

In this setup, both the size of the datasets and the need to process aggregate queries represent challenges for standard SPARQL query processing techniques. To overcome these limitations, materialized views can be created and used as a source of precomputed partial results during query processing.

Recent advances in peer-to-peer discovery of data sources and query processing techniques have made such queries feasible and potentially more frequent. The concurrent execution of multiple and often identical distributed aggregate queries can place a high burden on the data sources.

In-network aggregation can reduce this communication overhead substantially, . Sensors are arranged in a spanning tree rooted at the sink, each intermediate node receives messages from its children, computes an aggregate (e.g., SUM) of its children's and own values, and then forwards to its parent only a single message with the aggregate value.
If the LACP peers have non-matching port priority values, the values of the peer with the lower System Priority number (default is 32,768; range is 165,535) will override the other peer. ( Optional ) For active/passive firewalls only, select Enable in HA Passive State if you want to enable LACP pre-negotiation for the passive firewall.

Query processing in overlay networks has been receiving significant attention from researchers recently. Such systems offer flexibility and de-centralization. The challenge is to add representation and query capacity in such a networked environment, resulting in a peer-to-peer data management system.
Peer-to-peer networks are considered the new generation of distributed databases, termed peer-to-peer databases. With very large size, open architecture, and extreme dynamism and autonomy, approximate query answering is arguably the most promising approach for query answering in peer-to-peer
processes waste much bandwidth and processing power since each peer queries all of its neighbors. Our approach ber of nodes in the network. Their approach does not dis-tinguish the ratings for service (reliability) and ratings for every 5 queries for a peer. 3.1. Local and Aggregate Ratings; =
Peer-to-peer (P2P) networks came into existence as a means of sharing ﬁles and/or CPU cycles among end-users. Over time, they evolved from the anarchy execute aggregate queries and to maintain statistics over stored/shared data, networks and distributed data stream processing [Cormode and Garofalakis 2005; Hadjieleftheriou et al. 2005
