Optimal Aggregator Node Selection in Wireless Sensor Networks
نویسندگان
چکیده
In order to reduce number of data transmissions and improve the bandwidth and energy utilization in wireless sensor networks (WSNs), data aggregation or in-network processing techniques are needed. The simplest way to achieve data aggregation is to select data aggregator nodes. In this paper, we investigate optimal aggregator node selection in WSNs. The main idea of our approach is to perform a skyline query on the sensor nodes in WSNs in order to extract sensor nodes that are potential candidates for the leading role, and those that cannot possibly become an aggregator node.

متن کاملCollaborative Filtering Based Aggregator Node Selection in Wireless Sensor Networks
In typical WSN, the sensor nodes have limited resources such as battery power, computing capability and memory. In order to achieve the equal usage of limited resources in the wireless sensor networks (WSNs), we must aggregate the sensor data before passing it to the base station. Careful selection of the aggregator nodes in the data aggregation process results in reducing large amounts of comm...
