This paper presents the design of a new wireless sensor node (GAIA Soil-Mote) for precision horticulture applications which permits the use of precision agricultural instruments based on the SDI-12 standard. Wireless communication is achieved with a transceiver compliant with the IEEE 802.15.4 standard. The GAIA Soil-Mote software implementation is based on TinyOS. A two-phase methodology was d...

An understanding of the capabilities of the Mica mote light sensors is currently limited. To determine how much information data from the light sensors reveals about the environment, we performed a series of experiments designed to test the sensitivity of the light sensors to the time of day, the presence/absence of close objects, and different colors. Measuring the ambient light alone, we disc...

The analysis of the cycle 17 STIS CCD spectroscopic flats (Niemi 2010) pointed to the need to create a new dust mote image for the low resolution grating (L-mode) P-flats. This ISR describes the creation of the new L-mode P-flat from low resolution exposures taken during cycles 18 and 19. The document also analyzes the time dependence of the dust mote images as well as that of the intrinsic fla...

Energy conservation is an essential and critical requirement for a wireless sensor network with battery operated nodes intended for long term operations. Prior work has described different approaches to routing protocol designs that achieve energy efficiency in a wireless sensor network. Several of these works involve variations of mote-to-mote routing (flat routing) while some make use of lead...

Miniaturized, distributed, networked sensors called motes promise to be smaller, less expensive and more versatile than other sensing alternatives. While these motes may have less individual reliability, high accuracy for the overall system is still desirable. Sensor validation and fusion algorithms provide a mechanism to extract pertinent information from massively sensed data and identify inc...

This paper deals with the problem of tracking a radio controlled vehicle (RCV) fitted with LED’s moving within a wireless sensor network (WSN). The WSN test bed is made up of a number of Mica2 motes with fixed and know locations and equipped with light sensors. To reduce the overload of communications, power consumption, and allow for scalability, the network is divided into clusters, where mem...

In construction, the real-time monitoring of worker is necessary for ensuring safety in terms health and accidents. The technology advancement sensors wireless communication has inspired to implement Internet Things (IoT) construction site. With this motivation, study we have proposed a system that powered with long range (LoRa) IEEE 802.15.4 based Zigbee implementation. Worker mote, helmet det...

Motivated by the observation of topological states in $AB$-stacked ${\mathrm{MoTe}}_{2}/{\mathrm{WSe}}_{2}$, we construct symmetry-adapted Wannier and tight-binding model for quantum spin Hall bands this system. Our construction is based on symmetry analysis Bloch obtained from continuum moir\'e Hamiltonian. For parameters extracted first-principles calculations, find that can be described a de...

This particular paper describes our most recent work on our system called JAWS. This system is intended to control and monitor Wireless Sensor Network. In principle, JAWS is group of agents implemented on JADE platform. It consists of several agents that are able to communicate with Wireless Sensor Nodes and obtain values from particular sensor nodes called motes. We are also able to inject mob...
