Novel Scheme Of Fuzzy Based Concealing Sink Node With Fake Holes (F-Csh)

Due to the sink node crucial position, its location privacy is becoming one of the major issues in wireless sensor networks (WSNs) which requires ultimate protection. Particularly, the WSNs successfulness is endanger as the wireless transmission nodes are susceptive to illicit tracing and detection. While privacy of the message can be ensured through encryption content, this paper formalizes a novel efficient privacy preserving scheme to secure sink node location. The aim is to keep the location privacy of the sink node from being tracked using the traffic flow passive analysis. F-CSH is based on the concealing of the location of the main sink using fake sink holes been elected using fuzzy score function. In addition, comprehensive simulations proved that the proposed scheme significantly upgrades both delivery time and conservation energy cost compared with existing strategies.
