Water is considered as the most important resource in our life. Pipelines are considered as very important solution to transport water. So, due to the existence of the harsh environmental condition, different detection ways are not great to monitor pipelines. Therefore, all used systems need to be improved to become more efficient. For this reason,...

Water pipelines are one of the most vital structures to convey fresh water for consumption or irrigation over long distances. However, the major problem of water transportation pipeline is leak which can cause water resources loss, possible human injuries, and environmental pollution problems. For that, these pipelines must be carefully and real-ti...

Over the past few years, wireless sensor networks have gained significant attention. They have been distributed in the real world in order to collect valuable raw sensed data. Due to high density, WSNs (Wireless Sensors Networks) are exposed to faults and nasty attacks. Likewise, the sensors readings are inaccurate and unreliable, which make Wirele...

Border surveillance is one of the high priority in the security of countries around the world. Typical and traditional border observations involve troops and checkpoints at borders, but these do not provide complete security. One effective solution is the addition of smart fencing to enhance surveillance in a Border Patrol system. More specifically...

Outlier detection is the task of classifying test data that differ in some respect from the data that are available during training. This may be seen as one-class classification, in which a model is constructed to describe normal training data. In wireless sensor networks (WSNs), the outlier detection process is a necessary step in building sensor...

In the data mining literature, many outlier detection models can be found. However, these models are not suitable for the energy constrained WSNs because they assumed the whole data is available in a central location for further analysis. In this paper, we propose Distributed and Efficient One-class Outliers Detection Classifier (DEOODC) based on M...

An emerging class of Wireless Sensor Networks (WSNs) applications involves the acquisition of large amounts of sensory data from battery-powered, low computation and low memory wireless sensor nodes. The accuracy of sensor readings is without a doubt one of the most important measures to evaluate the quality of a sensor and its network. For this ca...

In Wireless Sensor Networks (WSNs), the accuracy of sensor readings is without a doubt one of the most important measures to evaluate the quality of a sensor and its network. For this case, the task amounts to create a useful model based on KPCA to recognize data as normal or outliers. Over the last years, Principal component analysis (PCA) has sho...

Outliers in wireless sensor networks are measurements that deviate from the normal model of sensed data and result from errors, events or malicious attacks on the network. The dynamic nature of sensor data and the specificity of the wireless sensor network make traditional outlier detection techniques unsuitable for direct application in such conte...
