Data Aggregation

چکیده
In Wireless sensor networks, a very common task is that of monitoring a large area in regards to some physical sensed value such as temperature. Usually the end user wants to examine and analyze this information, so they are collect in a central point we call the sink node. Due to the large amount of data transmitted as the scale of the network increases, it is important to combine several sensor readings in intermediate nodes along the way towards the requester and therefore to conserve energy. This process is known as data aggregation. However due to the nature of the wireless medium the communication in a WSN is error-prone and the aggregation techniques used must be aware and resilient to errors in message transmission.

EIDA: An Energy-Intrusion aware Data Aggregation Technique for Wireless Sensor Networks
Energy consumption is considered as a critical issue in wireless sensor networks (WSNs). Batteries of sensor nodes have limited power supply which in turn limits services and applications that can be supported by them. An efcient solution to improve energy consumption and even trafc in WSNs is Data Aggregation (DA) that can reduce the number of transmissions. Two main challenges for DA are: (i)...
متن کاملEffect of the Garlic Pill in comparison with Plavix on Platelet Aggregation and Bleeding Time
Abstract Introduction Platelet aggregation plays a significant role in the etiology of cardiovascular diseases. Therefore, treatments to inhibit platelet aggregation can reduce the risk of coronary thrombosis. Several studies indicated that garlic can inhibit platelet aggregation. This study aimed to determine the effect of garlic in comparison with Plavix on platelet aggregation. Materials ...
متن کاملA comprehensive experimental comparison of the aggregation techniques for face recognition
In face recognition, one of the most important problems to tackle is a large amount of data and the redundancy of information contained in facial images. There are numerous approaches attempting to reduce this redundancy. One of them is information aggregation based on the results of classifiers built on selected facial areas being the most salient regions from the point of view of classificati...
متن کاملAn input-oriented radial measure for returns to scale aggregation.
In production theory, it is necessary to be capable of predicting the production func- tion’s long-run behaviors. Hereof, returns to scale is a helpful concept. Returns to scale describes the reaction of a production function to the proportionally scaling all its input variables. In this regard, Data envelopment analysis (DEA) provides a com- prehensive framework for returns to scale evaluation...

The interaction of Congo Red CR with a series of Alkyltrimethylamoniumbromide CnTAB, N-hexadecylpyridinium bromide CPB and N-hexadecylpyridinium CPC were investigated using conductometry technique. It was observed that the formation of dye-surfactant ion pairs takes place at surfactant concentration far below the critical micelle concentration of the individual surfactants. Aggregation was refl...
