Intrusion detection plays an important role in the area of security in WSN. Detection of any type of intruder is essential in case of WSN. WSN consumes a lot of energy to detect an intruder. Therefore, the authors derive an algorithm for energy efficient external and internal intrusion detection. They also analyze the probability of detecting the intruder for heterogeneous WSN. This paper considers single sensing and multi-sensing intruder detection models. It is found that their experimental results validate the theoretical results.
