Scale Free Aggregation in Sensor Networks
Sensor networks are distributed data collection systems, frequently used for monitoring environments in which “nearby” data has a high degree of correlation. This induces opportunities for data aggregation, that are crucial given the severe energy constraints of the sensors. Thus it is very desirable to take advantage of data correlations in order to avoid transmitting redundancy. In our model,...
متن کاملan efficient protocol for data aggregation in wireless sensor networks
sensor networks generally consist of a very great number of sensor nodes which will be spread into a vast environment and aggregate data out of it. the sensor nodes are afflicted with some limitations as follows memory, reception, communication as well as calculation capability, and battery power. the transmission of a great amount of extra data increases data transmission and proportionally in...

Although structure...
متن کاملEffective Data Aggregation Scheme for Large-scale Wireless Sensor Networks
Energy preservation is one of the most important challenges in wireless sensor networks. In most applications, sensor networks consist of hundreds or thousands nodes that are dispersed in a wide field. Hierarchical architectures and data aggregation methods are increasingly gaining more popularity in such large-scale networks. In this paper, we propose a novel adaptive Energy-Efficient Multi-la...
متن کاملEnergy-Conscious Data Aggregation Over Large-Scale Sensor Networks
Recent advances in hardware technology facilitate applications requiring large numbers of sensor devices, where each sensor device has computational, storage, and communication capabilities. Since sensor devices are powered by ordinary batteries, power is a limiting resource in sensor networks. Power usage can be reduced by pushing part of the computation into the network to reduce communicatio...
