Sinkhole Attack: a Security Vulnerability in Wireless Sensor Networks

Computer Network Engineering

Wireless Sensor Networks(WSN) have found a wide range of applicability in our day-to-day life and also a bright future of interest because of its salient features such as lesser power consumption, low cost, and easier implementation, etc. This wide range of popularity and usability of these networks makes the security threats and their prevention as the hot topics for research. The security challenges and the various security vulnerabilities that occur in the wireless sensor networks have been surveyed and documented in this paper. One such vulnerability, Sinkhole attack is viewed in detail. The challenges in the detection of the attack, the approaches used to detect and prevent sinkhole attack have been briefed in this paper. Finally, a conclusion over the attacks and the work being carried out is stated.
