Exact In-Network Aggregation with Integrity and Confidentiality

network and conducting the aggregation process are delegated to a third-party service provider with a well provisioned distributed infrastructure (e.g., Microsoft’s SenseWeb [9]). Nevertheless, the provider may be untrustworthy and possibly malicious. Secure in-network aggregation mandates the following key security properties:

in-network processing problems related with multicasting and aggregation of data where processing locations can be chosen to reduce traffic. As using (or leasing) in-network processing capabilities comes at a certain cost (e.g., the corresponding resources cannot be used by other applications), there is a trade-off between additional processing and

We define the in-network aggregation process as follows: In-network aggregation is the global process of gathering and routing information through a multi-hop network, processing data at intermediate nodes with the objective of reducing resource consumption (in particular energy), thereby increasing network lifetime. We can distinguish between two approaches: † In-network

[3] defines the in-network aggregation process as follows: "In-network aggregation is the global process of gathering and routing information through a multi-hop network, processing data at intermediate nodes with the objective of reducing resource consumption, thereby increasing network lifetime." Figure 2 shows effect of data Aggregation.

Parallel Processing (Aggregation) (Message Flow Development)

For isolation and performance, it is possible to configuration an Aggregation to use alternate queues. This is done through an Aggregation Configurable Service. In this case, the Configurable Service creates a ^prefix _ that is used to identify differently named queues. The resulting queue names are:

Batch aggregation - Sitecore Commerce Server

28-11-2019  In the Sitecore Experience Database (xDB), the aggregation process groups and reduces live or historical data from the collection database so that it can be used by the reporting database and Sitecore reporting applications. In a scalable xDB architecture, aggregation is usually performed on one or more dedicated Processing servers.

is usually applied in cases where the aggregation process is independent of the network topology. In such scenarios the aggregator role is typically assigned to one of the nodes basedontheexecutionoftheunderlyingaggregatorelectionprotocol(e.g.[13]).More-over, this role is usually temporary and changed (randomly) between nodes in order to distribute the increasing costs for the aggregation

Secure In-Network Aggregation in Wireless Sensor

Data aggregation or in-network aggregation (Yao et al., 2002) is a natural approach for reducing data transmission in wireless sensor networks. Aggregation techniques remove redundancy in sensed data. The aim of in-network data processing is to combine the sensed raw data from several sensors using aggregation functions namely MIN, MAX, MEDIAN, MODE, SUM, COUNT, AVERAGE, etc., and

Processing multiple aggregation queries in geo-sensor

To process aggregation queries issued through different sensors as access points in sensor networks, existing algorithms handle queries independently and perform in-network aggregation only at the query time. As a result of ad-hoc and independent execution of queries, no partial result is sharable and reusable among the queries.

In wireless sensor network, data fusion is considered an essential process for preserving sensor energy. Periodic data sampling leads to enormous collection of raw facts, the transmission of which would rapidly deplete the sensor power. In this paper, we have performed data aggregation on the basis of entropy of the sensors. The entropy is computed from the proposed local and global ...

Based on this new networking paradigm, we formulate the Constrained Virtual Steiner Arborescence Problem (CVSAP) which asks for optimal locations to perform in-network processing, in order to jointly minimize processing costs and network traffic while respecting link and node capacities.

Abstract. Information aggregation is an important operation in wireless sensor networks executed for the purpose of monitoring and reporting of the environ-mental data. Due to the performance constraints of sensor nodes the in-network form of the aggregation is especially attractive since

In addition to in-network data aggregation, there exist many in-network processing techniques, such as data fusion, data elimination, data filtering, and data compression, to reduce the communication overhead.

Collision-free schedule is generated by a distributed algorithm for performing data aggregation in wireless sensor network. The time latency of aggregation schedule is minimized using greedy strategy. In a recent research , an aggregation scheme called smart aggregation is developed for continuous monitoration in sensor networks.

Aggregating results of parallel data processing

I want to process data in parallel using a cluster of ServiceMix / ActiveMQ / Camel. It seems I can achieve that by first splitting the data up, then distributing it via multiple JMS messages and an ActiveMQ network of brokers. The part which makes it hard though is that I need to aggregate all results from all nodes in the end.
