Network energy consumption is a critical factor determining the WSN development speed. Various techniques are available for the data generated by the sensor nodes to send it efficiently to base station. Along with this possibility there are many other possibilities that can be taken into consideration and as a result of these techniques and rise in the number of the techniques the wireless sensor network is emerging from the very start, when this field is introduced. In-network data fusion is needed for energy-efficient information flow from a plurality of sensors to a central server or sink. Many techniques has been developed and tested and various techniques succeeded in achieving the ultimate goal of more efficient utilization of the resources. As data is propagated towards the sink, multiple levels of data fusion are likely. The data fusion at various levels should be synchronized in order to fuse data effectively. This paper presents a descriptive and broad review of existing techniques of data fusion. In the survey of the development life cycle of the wireless sensor networks(WSNs) it is felt that the field of data fusion is ignored and remain isolated as compared to other fields researched by the research community. The paper discusses majority of the techniques that are having great impact on the way the research is carried out and provides a path way for the futuristic research in this field.
