The analysis of data fusion energy consumption in WSN

Wireless sensor networks (WSN) nodes are usually resource-constrained, and the energy resources can affect the entire sensing network lifetime, therefore, the energy consumption problem is usually needed to be considered in the sensor network data fusion. This article introduces several data fusion methods for WSN, especially analyzes several kinds data fusion methods based on routing protocol. In the case of non-full data fusion, choosing the route of low energy consumption has more advantages in reducing the data amount, reducing network congestion, and extending the network cycle.
