Enhancing the data quality in wireless sensor networks — A review

The area of wireless sensor network (WSN) has always been the pivotal point of attention for various researchers for more than a decade. Although WSN is featured with various advantageous characteristics, still it is shrouded with various issues that dampen the spirit of researchers. Various significant problems that are being addressed in the literature are energy issues, security issues, bandwidth issues, routing issues, etc. This paper emphasizes the issues of data quality from the data aggregation or fusion process in wireless sensor network. The paper has presented a simple description of data, its essential characteristics, and has discussed some of the significant literature that discusses about enhancing the data quality as well as fault tolerant system in wireless sensor network. Finally, the paper briefs about the research gap that has been identified from the literature review.
