Abstract

In wireless sensor network, in-network data aggregation can eliminate redundancy, improve data accuracy and thus prolong the lifetime of network. However, most of data aggregation technologies assumed that the aggregator node has been receiving all the data when it performers the aggregation operation, these methods give larger latency to the transmission of network's data and affect the accuracy of network. Therefore, this paper presents a new data aggregation technology, conjiguring carefilly the aggregator node's timeouts through making use of a new aggregation timing control scheme, which is to achieve a good trade-off between energy efficiency and data accuracy.
