This paper provides a comprehensive survey on addressing the target coverage problem to maximize the network lifetime by placing the minimum number of sensors and without affecting the quality of monitoring. Energy utilization is one of the important key challenges in the research area of sensor networks. Deployment of sensor nodes should be with extreme coverage and connectivity but with less ...

In most cases, it is considerably difficult to directly measure structural vibration with a lot of sensors because of complex geometry, time and equipment cost. For this reason, this paper deals with the problem of locating sensors on a plate model by four advanced sensor placement optimization (S.P.O) techniques. It also suggests the evaluation index representing the characteristic of orthogon...

Systems, complex or otherwise, can be monitored through sensors placed at various functional levels to infer information about system reliability parameters (and by extension, reliability characteristics). Sensor placement directly affects the quantity and utility of inferred information, and need to be judiciously located throughout the relevant system. Sensors can be embedded or attached upon...

We present a novel approach that provides the necessary localization and mapping capabilities to allow a dynamic placement of independent sensing agents. The presented approach allows to build complex sensor configurations using simple agents that carry basic sensors, like e.g. low-resolution cameras, which can be combined to high precision and high accuracy systems through fusion of their info...

A good placement of sensors is crucial to get good performance in detecting and isolating faults. Here, the sensor placement problem is cast as a minimal cost optimization problem. Previous works have considered this problem with qualitative detectability and isolability specifications. A key contribution here is that quantified detectability and isolability performance is considered in the opt...

Accurate temperature estimation of high density active power electronic systems is vital for dynamic thermal management. Accurate and reliable estimation is especially important in regions that are close to failure, either due to high temperature or significant materials or component sensitivity. Improved estimation can support lower safety factors and enhanced system performance. An investigat...
