Reviewing the process of data fusion in wireless sensor network: a brief survey

Wireless sensor network is deployed on human inaccessible region to perform a very sensitive task where various external and internal factors affect the results being accumulated by the sensing node. Data fusion is one such technique. With the upcoming applications of wireless sensor network, it is also accompanied by various power and quality related issues. However, it was seen that whatever are the challenges or issues, it affects basically the data collection techniques from sensor nodes and corresponding forwarding to sink node. Hence, this paper aims to perform an exclusive investigation of the data fusion with respect to various standard architectures, standard algorithms and techniques investigated in the past study for performing data fusion, followed by open issues and research gap in the existing system adopted for enhancing the efficiency of data fusion techniques.
