无线传感器网络由具有感知和通信能力的传感器节点组成。我们专注于能量受限的传感器网络中的数据聚合问题。数据聚合算法的主要目标是以节能的方式收集和聚合数据，从而提高网络的生命周期。在这篇文章中，我们提出了一个调查的数据聚合算法在无线传感器网络。我们比较和对比不同的算法的基础上的性能指标，如生命周期，延迟和数据的准确性。最后，我们总结了未来可能的研究方向。
Wireless sensor networks consist of sensor nodes with sensing and communication capabilities. We focus on data-aggregation problems in energy-constrained sensor networks. The main goal of data-aggregation algorithms is to gather and aggregate data in an energy efficient manner so that network lifetime is enhanced. In this article we present a survey of data-aggregation algorithms in wireless sensor networks. We compare and contrast different algorithms on the basis of performance measures such as lifetime, latency, and data accuracy. We conclude with possible future research directions.
