In [114], Radivojac et al. develop an algorithm for intrusion detection in a supervised framework, where there are far more negative instances than positive (intrusions). A neural-network-based classifier is trained at the base station using data where the smaller class is over-sampled and the larger class is under-sampled [25]. An unsupervised approach to the outlier detection problem in sensor networks is presented in [103], where kernel density estimators are used to estimate the distribution of the data generated by the sensors, and then the outliers are detected depending on a distance-based criterion.

48] have studied the theoretical aspects of this problem with application to energy optimization. They illustrate an optimal algorithm for clustering the sensor nodes such that each cluster (that is characterized by a master) is balanced and the total distance between the sensor nodes and the master nodes is minimized. Some other approaches in this regard are available in [26, 135]. Algorithms for clustering the data spread over a sensor network are likely to play an important role in many sensor-network-based applications.
