Data Aggregation and Query Processing in WSN
A wireless sensor network (WSN) has a wide range of important applications such as remote environment monitoring , target tracking etc. This has been enabled by the availability of sensors that are smaller, cheaper and intelligent. These sensor nodes are equipped with wireless interfaces with which they can communicate with one another to form a network. The design of a WSN depends significantl...
متن کاملData Filtering and Aggregation in a Localisation WSN Testbed
The main challenge in wireless networks is to optimally use the confined radio resources to support data transfer. This holds for large-scale deployments as well as for small-scale test environments such as test-beds. We investigate two approaches to reduce the radio traffic in a test-bed, namely, filtering of unnecessary data and aggregation of redundant data. Both strategies exploit the fact ...
متن کاملPower-efficient Hierarchical Data Aggregation using Compressive Sensing in WSN
Compressive Sensing (CS) method is a burgeoning technique being applied to diverse areas including wireless sensor networks (WSNs). In WSNs, it has been studied in the context of data gathering and aggregation, particularly aimed at reducing data transmission cost and improving power efficiency. Existing CS based data gathering work [2] [4] [5] in WSNs assume fixed and uniform compression thres...
متن کاملEnergy Efficient Techniques for Data aggregation and collection in WSN
A multidisciplinary research area such as wireless sensor networks (WSN) have been invoked the monitoring of remote physical environment and are used for a wide range of applications ranging from defense personnel to many scientific research, statistical application, disaster area and War Zone. These networks are constraint with energy, memory and computing power enhance efficient techniques ar...
متن کاملCluster Based Compressed Data Aggregation and Routing in WSN
Due to non uniform distribution of nodes, there is an imbalance of energy consumption among the nodes in cluster-based wireless sensor networks. Based on this problem, we propose an efficient data aggregation tree for communication and routing based on the previous clustering architecture. Here based on the parameters such as Residual Energy, Node Density and Load cluster heads are elected usin...
