In this paper, we study the problem of constructing an energy-efficient data aggregation tree for wireless sensor networks. Our aim is to reduce the cost of transmitting data by aggregating data at appropriate intermediate nodes. We proposed a polynomial time algorithm Energy-Efficient Data Aggregation Tree (EEDAT), to reduce the transmission cost...
Data aggregation represents one of the most challenging and well-studied subjects in the Wireless Sensor Networks (WSN) literature. The energy constraints of sensor nodes call for energy-efficient data aggregation methods so as to prolong network lifetime. Among other approaches, Mobile Agents (MAs) have been proposed to improve the performance of...

... Initially, all the bit entries in the buffer are unset. After that, sensors keep track of the time and at the end of each time slot each sensor checks whether there is any detected event within this time slot [22]. If yes, the bit value corresponding to this time slot is set. ...
Wireless Sensor Network is a set of sensors that are integrated with a physical environment. Assortment of
sensor nodes systematized into a network is also known as Wireless Sensor Networks .Now days, a wireless sensor networks have emerged as one of the most exciting fields in Computer Science research as well as the distributed systems. The main limitations of Wireless Sensor Networks are characteristics of sensor nodes and nature of sensor data generated by networks. In sensor networks data mining is the method of selecting application-oriented standards and patterns with acceptable accuracy from fast and continuous flow of data
streams from sensor networks. Data mining methods has to be fast to process high-speed arriving data. Data mining, as the continuance of multiple intertwined disciplines, consisting statistics, machine learning, pattern recognition, database systems, information retrieval, World-Wide Web, visualization, and lots of application domains, has made great progress in the past decade. Data mining is one of the most imperative approaches by which useful patterns in data with nominal user intervention are known and available information of users and analysts to make decisions relayed on their vital organizations to adopt. To ensure that the advances of data mining research and technology will competently benefit the progress of science and
engineering, it is important to scrutinize the challenges on data mining posed in data-intensive science and engineering and explore how to further develop the technology to assist new discoveries and advances in science and engineering. Main objective of this review paper is comparative analysis of various data aggregation; mining techniques are discuses with associate’s advantage of accuracy, complexity, reduces energy consumption. Other factors such data mining techniques that affect the prediction are also discussed.

Wireless sensor networks are an emerging area of research interest and a network of distributed sensors grouped together to monitor physical or environmental conditions, like pressure, temperature, sound etc. The development of wireless sensor networks was first motivated by military applications; today such networks are used in several industrial, non- industrial and consumer applications, such as industrial process monitoring and control, machine observation, health monitoring, etc. By framework sensor networks as virtual databases, we can offer a nonprocedural-programming interface suitable to data management system. We squabble here that in order to attain energy efficient and useful completion, query-processing operators should be implementing within the sensor network and that estimated query results would play a key role in network system. We study that in network implementations of database operators need novel data centric routing mechanism, as well as a reassessment of conventional network and database interface layering. Wireless sensor networks are presently getting considerable concentration due to their unrestrained prospective.
