Intrusion detection is one of the most important issues in Wireless Sensor Networks (WSNs). WSN sensors distribution plays an important role in intrusion detection process; uniform distribution of sensors yields the same intruder detection capability for all WSN points. Many applications require different levels of security (i.e. the security level should be increased around some specific locations in WSN. Most of the related works focus on using normal and uniform distributions in 2D WSN applications with homogenous sensors. Many applications may be applied in 3D such as space monitoring and underwater ecosystem which still need extensive studies for intruder success probability.
