<title>Abstract</title> Wireless Sensor Network (WSN) refers to a network of devices that can communicate the informa- tion gathered from a monitored field through wireless links. WSNs measures environmental conditions like temperature, sound, pollution levels, humidity, wind, etc. WSN’s data fault detection is a challenging problem due to presence of sensors in unpredictable areas. The data fault detection has to be precise and accurate, so that it can be used for weather prediction, disease prediction etc. In re…
