### Chapter 1. Introduction to Distributed Sensor Networks

Currently, detection and tracking systems use a large number of different types of sensors. Because of the relatively low cost of sensors, many duplicate sensors of the same type are used to insure increased fault tolerance. The common practice is to assign each sensor of sensor cluster to handle on specific task. For example, while tracking multiple target, one sensor cluster is assigned to track one target only and any information it may collect about other targets is not utilized.

### Chapter 2. Region-Guarding Problem in 3-D Areas

This chapter studies the optimal inspection of autonomous robots in a complex pipeline system. We solve a 3-D region-guarding problem to suggest the necessary inspection spots. The proposed hierarchical integer linear programming (HILP) optimization algorithm seeks the fewest spots necessary to cover the entire given 3-D region. Unlike most existing pipeline inspection systems that focus on designing mobility and control of the explore robots, this chapter focuses on global planning of the thorough and automatic inspection of a complex environment. We demonstrate the efficacy of the computation framework using a simulated environment, where scanned pipelines and existing leaks, clogs, and deformation can be thoroughly detected by an autonomous prototype robot.

### Chapter 3. Expectation–Maximization for Acoustic Source Localization

Wideband source localization using acoustic sensor networks has been drawing a lot of research interest recently. The maximum likelihood (ML) is the predominant objective which leads to a variety of source localization approaches. However, the robust and efficient optimization algorithms are still being pursuit by researchers since different aspects about the effectiveness of such algorithms have to be addressed on different circumstances.

### Chapter 4. Coordinate-Free Coverage in Sensor Networks via Homology

We introduce tools from computational homology to verify coverage in an idealized sensor network. Our methods are unique in that, while they are coordinate-free and assume no localization or orientation capabilities for the nodes, there are also no probabilistic assumptions. The key ingredient is the theory of homology from algebraic topology. We demonstrate the robustness of these tools by adapting them to a variety of settings, including static planar coverage, 3-D barrier coverage, and time-dependent sweeping coverage. We also give results on hole repair, error tolerance, optimal coverage, and variable radii. An overview of implementation is given.

### Chapter 5. Coverage Assessment and Target Tracking in 3D Domains

Recent advances in integrated electronic devices motivated the use of wireless sensor networks (WSNs) in many applications including domain surveillance and mobile target tracking, where a number of sensors are scattered within a sensitive region to detect the presence of intruders and forward related events to some analysis center(s).

### Chapter 6. A Stochastic Preserving Scheme of Location Privacy

Continued advances in positioning technologies and mobile devices have increased the demand for location-based services (LBSs) in distributed sensor networks. Every LBS provider requires the sensor nodes to report their location information as the quality of service strongly depends on the information.

### Globales Erdungssystem in urbanen Kabelnetzen

Bedingt durch die Altersstruktur vieler Kabelverteilnetze mit der damit verbundenen verminderten Isolationsfestigkeit oder durch fortschreitenden Kabelausbau ist es immer häufiger erforderlich, anstelle der Resonanz-Sternpunktserdung alternative Konzepte für die Sternpunktsbehandlung umzusetzen. Die damit verbundenen Fehlerortungskonzepte bzw. die Erhöhung der Restströme im Erdschlussfall führen jedoch aufgrund der hohen Fehlerströme zu neuen Anforderungen an die Erdungs- und Fehlerstromrückleitungs-Systeme. Lesen Sie hier über die Auswirkung von leitfähigen Strukturen auf die Stromaufteilung sowie die Potentialverhältnisse in urbanen Kabelnetzen bei stromstarken Erdschlüssen. Jetzt gratis downloaden!
