Coverage and connectivity are two important performance metrics in wireless sensor networks. In this paper, we study the sensor placement problem to achieve both coverage and connectivity. Instead of using the simplistic disk coverage model, we use our recently proposed confident information coverage model as the sensor coverage model. The grid approach is applied to discretize the sensing fiel...

In this study, efficient methods for optimal sensor placement (OSP) based on a new geometrical viewpoint for damage detection in structures is presented. The purpose is to minimize the effects of noise on the damage detection process. In the geometrical viewpoint, a sensor location is equivalent to projecting the elliptical noise on to a face of response space which is corresponding to the sens...

This paper addresses the problem of robust sensor placement for large scale linear time-invariant systems. Two different concepts of robustness are analyzed: 1) the robustness with respect to one sensor failure, and 2) the robustness with respect to one link failure. We show that both aforementioned problems can be posed as a set cover problem. Due economic constraints we may be interested in c...

In this paper, a nominal sensor placement methodology for leak location in Water Distribution Networks is presented. To reduce the size and the complexity of the optimization problem a clustering technique is combined with the nominal sensor placement methodology. Some of the pressure sensor placement methods for leak detection and location in water distribution networks are based on the pressu...

Adequate coverage is one of the main problems for Sensor Networks. The effectiveness of distributed wireless sensor networks highly depends on the sensor deployment scheme. Given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save cost of sensors for locating in grid points. In many working environments, for achieving good coverage, we m...

In recent years with advances in wireless communication technology, sensing technology can be used for a wide variety of applications and systems with vastly varying requirements and characteristics, such as environmental monitoring, disaster management, factory automation, health care and military. Typical sensor network consists of a large number of spatially distributed autonomous sensor dev...

This technical report summarizes the intrinsic sensor parameters for the range, IR and color sensor used in the Fort Carson data collection and explores sensor-to-sensor image mapping under di erent assumptions regarding relative sensor placement. The default case is to assume perfectly boresight aligned placement, and then the implications of di erent deviations from this perfect placement are...

Research activity in the area of wireless sensor networks(WSNs) has grown dramatically in the past few years, driven by advances in miniaturized hardware, and motivated by a vast array of potential applications. Typical scenarios for large-scale WSNs contain multiple sources and multiple sinks. In WSNs, energy is the most critical resource constraint and the lifetime of a WSNs is dependent on l...

Sensor placement is a fundamental issue in wireless sensor networks (WSNs). The sensorpositions can be predetermined to guarantee the quality of surveillance provided by the WSN. However, in remote or hostile sensor field, randomised sensor placement often becomes the only option. In this paper, we survey existing random node placement strategies. We categorise random placement strategies into ...
