The Research of Data Aggregation in Wireless Sensor Networks

摘要

Energy consumption of wireless sensor networks has always been the focus of people’s studies. The introduction of data aggregation reduces the energy consumption of nodes to some extent, which can be combined to reduce the need for redundant data transmission of data packets thereby reducing the number of nodes in the energy consumption. Based on the comparing of current protocols of building aggregation tree, this article proposes a data aggregation tree algorithm that bid to the center of the roots of the tree structure and through simulation shows that this protocol is effective.
