摘要：

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.
