Wireless sensor networks (WSNs) allow for wireless communications between embedded devices that can be deployed for long periods in harsh environments. Because of their flexibility, WSNs are applicable to a wide variety of domains and a lot of research has been done to determine the best topology for a network, or the best routing protocol. Much of this research is aimed to solve a specific pro...

The Internet of Things (IoT) is expected to provide better services through the interaction of physical objects via the Internet. However, its limitations cause an interoperability problem when the sensed data are exchanged between the sensor nodes in wireless sensor networks (WSNs), which constitute the core infrastructure of the IoT. To address this problem, a Sensor Registry System (SRS) is ...

People-centric sensing with smart phones can be used for large scale sensing of the physical world at low cost by leveraging the available sensors on the phones. However, the sensed data submitted by participants is not always reliable as they can submit false data to earn money without executing the actual task at the desired location. To address this problem, the authors propose ILR, a scheme...

Abstract—Nitrogen fertilizer is the most used and often the most mismanaged nutrient input. Nitrogen management has tremendous implications on crop productivity, quality and environmental stewardship. Sufficient nitrogen is needed to optimum yield and quality. Soil and in-season plant tissue testing for nitrogen status are a time consuming and expensive process. Real time sensing of plant nitro...

An algorithm for image matching of multi-sensor and multi-temporal satellite images is developed. The method is based on the SIFT feature detector proposed by Lowe in (Lowe, 1999). First, SIFT feature points are detected independently in two images (reference and sensed image). The features detected are invariant to image rotations, translations, scaling and also to changes in illumination, bri...

Facilitation is a major force shaping the structure and diversity of plant communities in terrestrial ecosystems. Detecting positive plant-plant interactions relies on the combination of field experimentation and the demonstration of spatial association between neighboring plants. This has often restricted the study of facilitation to particular sites, limiting the development of systematic ass...

A dynamical model of the neuro-musculo-skeletal mechanics of a cat hindlimb has been developed to investigate the feedback regulation of standing posture under small perturbations. The model is a three-joint limb, moving only in the sagittal plane, driven by 10 musculotendon actuators, each having response dynamics dependent on activation kinetics and muscle kinematics. Under small perturbation...

In this paper, we investigate the facts of ensuring secure sensed data in a balanced energy network backbone, and propose Enhanced an Energyefficient Data Privacy Protection Scheme for wireless sensor networks (E-EDPPS). In wireless sensor networks (WSNs), sensors may be deployed in an unpredictable environment where a limited energy of the sensor nodes has led to the development of EEDPPS. It ...

Traditional spectral classi®cation of remotely sensed images applied on a pixel-by-pixel basis ignores the potentially useful spatial information between the values of proximate pixels. For some 30 years the spatial information inherent in remotely sensed images has been employed, albeit by a limited number of researchers, to enhance spectral classi®cation. This has been achieved primarily by ®...
