Wireless Sensor Networks (WSNs) are specialized network of large number of sensor equipped nodes which are spatially deployed over the region of interest where the nodes may be stationary or mobile in nature. Wireless sensor networks are a group of small untethered sensor devices which are densely populated in a specific target area, where they collaborate in an ad-hoc manner to sense phenomena and report sensed data for various uses. The paper reports the techniques to detect node replication also called clone node attacks in the Static Wireless Sensor Networks (SWSN) and critically reviews them. The focus of the paper is to highlight and discuss various techniques to deal with node replication attack in static WSNs.
