In this paper, we evaluated several network routing energy models for smart farm application with consideration of several factors, such as mobility, traffic size and node size using wireless ZigBee technology. The energy models considered are generic, MICA and Zigbee compliant MICAz models. Wireless sensor networks deployment under several scenarios are considered in this paper, taken into account commercial farm specification with varying complex network deployment circumstances to further understand the energy constraint and requirement of the smart farm application. Several performance indicators, such as packet delivery ratio, throughput, jitter and the energy consumption are evaluated and analysed. The simulation result shows that both throughput and packet delivery ratio increases as the nodes density is increased, indicating that, smart farm network with higher nodes density have a superior Quality of Service (QoS) than networks with sparsely deployed nodes. It is also revealed that traffic from the mobile nodes causes increase in the energy consumption, overall network throughput, average end-to-end delay and average jitter, compared to static nodes traffic. Based on the results obtained, the Generic radio energy models consumed the highest total energy, while MICAz energy consumption model offers the least consumption, having the lowest ‘Idle’ and ‘receive’ modes consumption. The MICAz model also has the lowest total consumed energy as compared with the other energy models, suggesting that it is the most suitable energy model that should be adopted for future smart farm deployment.

ABSTRACT: Cognitive radio sensor network (CRSN) is a new generation of communication systems that wants to solve the overcrowded spectrum utilization of the unlicensed bands. It has combined sensor networks and cognitive radio technology, so it has the challenges of energy restriction of sensors and also dynamic spectrum access of the cognitive radio network. On the other hand, considering both of these challenges in the routing protocol plays a basic role in network performance and we can’t apply the routing protocols that have been proposed for wireless sensor networks and cognitive radio networks, separately, in the CRSN. Therefore, this article has tried to provide a new spectrum and energy-aware routing protocol in which the source is able to choose the most stable route in the aspect of node residual energy or spectrum access probability. Not only can considering the nodal residual energy and spectrum access in the route discovery process avoid repetitive link failure, but it also can increase the network lifetime. This protocol has been compared with ESAC, SCR, ERP, and SER. The result of this comparison has shown that our protocol reduces end-to-end delay, control overhead, throughput, and lifetime in comparison to other protocols, especially in small-scale networks.

Ianya adalah kombinasi rangkaian sensor dan teknologi radio kognitif. Oleh itu, ia mempunyai cabaran sekatan tenaga pada sensor dan kemasukan spektrum secara dinamik pada rangkaian radio kognitif. Pada masa sama, dengan mengambil kira kedua-dua cabaran pada protokol rangkaian ini telah memainkan peranan asas pada prestasi rangkaian dan kami tidak boleh mengguna pakai protokol rangkaian yang telah diguna pakai pada rangkaian sensor tanpa wayar dan rangkaian radio kognitif secara asing dalam CRSN. Oleh itu, artikel ini cuba menyediakan spektrum baru dan pengawasan tenaga pada protokol rangkaian, di mana sumber boleh memilih laluan rangkaian yang stabil dengan mengambil kira pada aspek baki tenaga nod atau kebarangkalian akses spektrum. Selain itu, ianya dapat mengelakkan kegagalan laluan berulang juga menambahkan jangka hayat rangkaian. Protokol ini telah dibandingkan dengan ESAC, SCR, ERP dan SER. Perbandingan keputusan menunjukkan protokol ini mengurangkan kelewatan hujung-ke-hujung, mengawal kesesakan, mambaiki jumlah penghantaran dan menambah tempoh hayat berbanding protokol lain, khususnya pada rangkaian skala kecil.

I recenti progressi nella tecnologia applicata alla produzione dei system-on-a-chip hanno permesso lo sviluppo di piccoli dispositivi per il rilevamento a basso costo, a bassa potenza e multifunzione, che sono in grado di svolgere attività quali il rilevamento, l'elaborazione dati e la comunicazione.
Una rete di sensori wireless (WSN) è una rete distribuita che consiste, in generale, di un gran numero di nodi di sensori, densamente distribuiti su un'ampia area geografica per tracciare un determinato fenomeno fisico.
Le reti di sensori wireless sono oggigiorno utilizzate in un'ampia gamma di applicazioni come quelle mediche, industriali, militari, ambientali, scientifiche e in reti domestiche.
In tutte queste applicazioni, la sincronizzazione temporale è un componente molto importante di una rete di sensori wireless, come del resto in ogni sistema distribuito.
Questa tesi ha come scopo principale lo studio dei protocolli esistenti che consentono di risolvere il problema della sincronizzazione tra i nodi di una rete wireless, analizzando in particolare le tecniche TPSN e FTSP. Queste tecniche sono poi state implementate all'interno di una rete wireless di sensori 6LoWPAN già esistente, osservandone poi le performance tramite una serie di test effettuati tramite l'utilizzo della rete all'interno di un ambiente reale.

Surface Plasmon Resonance (SPR) sensors are thin-film refractometers that measure changes in the refractive index that take place at the surface of a metal film supporting a surface plasmon (Homola, 2008).
The research activity consisted on a study and realization of innovative Surface Plasmon Resonance based sensors and of their applications, in particular for the environment monitoring.
In order to investigate the possibility of creating innovative SPR sensors, computer simulations of optical structures supporting surface plasmon polaritons and comprising peculiar materials were implemented. In particular SPR sensors based on metals showing Inverted Surface Plasmon Resonance and a single layer of Graphene (SGL) were simulated. An article has been submitted on this study.
Surface Plasmon Resonance sensor prototypes were also realized in laboratory. By means of a first SPR sensor with dynamic setup, measurements with Helium and Pentane gases were made, then an SPR sensor with a static setup was assembled, refined and as a following improvement in the optical components an adaptive mirror also introduced, which was able to counteract, if present, a lens defocus, spherical aberration, coma and astigmatism .
Moreover the elements of a feasible wireless sensor network based on Surface Plasmon Resonance sensors, the possible data that can be inferred from a SPR sensor and a possible data handling strategy were determined along with an evaluation of the sensor module energy requirements.
Then two small wireless sensor network test setups were implemented in laboratory, each one composed of two SPR sensors controlled by a computer or a microcontroller, ZigBee antennas and a main computer for the data reception and diffusion into Internet.
The feasibility of a Wireless Sensor Network based on SPR sensors, conceived for environmental pollutants detection and with broadband internet connection, has been demonstrated and two different laboratory setups for a test Wireless Sensor Network based on Surface Plasmon Resonance Sensors were realized.I sensori basati sulla plasmonica di superficie (SPR) sono rifrattometri, basati sulla fisica dei film sottili, che misurano le variazioni di indice di rifrazione che avvengono sulla superficie di uno strato metallico supportante un plasmone di superficie (Homola , 2008). L’ attività di ricerca si è sviluppata come uno studio ed implementazione di sensori SPR innovativi e delle loro possibili applicazioni, in particolare per la rilevazione di sostanze inquinanti. Sono stati simulati in ambiente Matlab sensori SPR innovativi, comprendenti materiali peculiari. Tali sensori comprendono in particolare metalli mostranti una Risonanza Plasmonica Invertita (ISPR), oltre che un singolo strato di Graphene (SGL). Un articolo è stato sottomesso su tali studi. Sono stati inoltre implementati in laboratorio vari prototipi di sensori basati sulla plasmonica di superficie. Innanzi tutto sono state effettuate delle misure di riflettività con i gas elio e pentano mediante un sensore basato sulla plasmonica di superficie e con un setup dinamico, quindi è stato creato un nuovo sensore utilizzante un un sistema ottico di tipo statico ed un prisma cilindrico ad alto indice di rifrazione, migliorando il più possibile la qualità del fascio ottico e filtrandolo opportunamente. Altresì è stato innovativamente utilizzato nel setup ottico uno specchio deformabile, in grado di correggere le aberrazioni ottiche presenti nello stesso. Oltre a ciò sono stati individuati i possibili elementi di una rete wireless di sensori SPR progettata per il monitoraggio ambientale, i dati ottenibili da un sensore SPR, una strategia per la diffusione dei dati ed una stima dei consumi energetici. Infine sono stati implementati in laboratorio due diversi setup di prova per una piccola rete wireless di sensori, formata da due sensori SPR controllati da un computer o da un microcontrollore, antenne ZigBee e da un computer principale per la ricezione, analisi e diffusione in Internet dei dati. L’ attività di ricerca presentata in questa tesi ha quindi dimostrato la possibilità della creazione di una rete wireless di sensori basati sulla Plasmonica di Superficie e con accesso Internet a banda larga, finalizzata alla rilevazione di sostanze inquinanti in ambiente acquoso, e due piccole versioni di prova della stessa sono state implementate in laboratorio.

La presente tesi si focalizza sullo sviluppo di innovative Wireless Sensor Network con relative applicazioni orientate all’IoT, valutando e analizzando i principali protocolli di comunicazione e implementando sistemi di gestione delle reti sia in locale che da remoto. Nello specifico ci si è concentrati su due use cases: Wireless Sensor Network (WSN) per il controllo di un sistema di illuminazione e reti diffuse di sensori low-cost per il monitoraggio sismico. In relazione al primo ambito si è realizzato un sistema intelligente capace di monitorare da remoto ed in tempo reale i corpi illuminanti. I principali elementi dell'architettura realizzata sono il sistema di controllo dell'impianto di illuminazione, il sistema di rilevamento, il sistema di gestione e il sistema di illuminazione. I primi due elementi consentono l'acquisizione di informazioni relative al livello di illuminamento e alla temperatura colore (CCT) nel sito di analisi, il sistema di gestione integra funzioni di monitoraggio locale e remoto dei parametri illuminotecnici per il controllo, mentre il sistema di illuminazione è composto dai corpi illuminanti.
Per quanto riguarda il secondo ambito applicativo si è sviluppata un'unità di sensing low-cost, composta da accelerometri che, attraverso i dati rilevati è in grado di registrare terremoti, rilevando sia eventi di bassa magnitudo che significativi. Dai risultati ottenuti nelle prove effettuate sul campo, il sistema assicura prestazioni analoghe rispetto a quelle della rete sismica nazionale dell'Istituto Nazionale di Geofisica e Vulcanologia (INGV). Vista l'ottima precisione ottenuta dall'unità di sensing, il dispositivo può essere utilizzato per incrementare e creare una rete diffusa per il monitoraggio di edifici strategici, come scuole e ospedali, per la realizzazione di mappe di scuotimento e per la creazione di sistemi intelligenti di Earthquake Early Warning (EEW) per l'allerta precoce, basati sulle architetture di Internet of Things.This thesis focuses on the development of an innovative Wireless Sensor Network for IoT applications. An evaluation of the main communication protocols and an implementation of the network's management system for both local and remote control and monitoring is performed. Specifically, it deals with the two use cases: Wireless Sensor Network (WSN) for lighting system control and low-cost sensor networks for seismic monitoring. A smart lighting system has created capable of remotely and real time control the lighting performance. The main elements of the developed architecture are the control system, the detection system, the management system and the lighting system. The first two elements allow the acquisition of information relating to the level of illumination and the color temperature (CCT) in the analysis site, the management system integrates local and remote monitoring functions of the lighting parameters for control, while the lighting system is composed of LED fixtures. A low-cost sensing unit, composed of MEMS accelerometers, has developed for seismic applications. Through the data collected by this device it is possible to recording earthquakes of several intensity. During the field tests the obtained results show similar performance to the national seismic network of the National Institute of Geophysics and Volcanology (INGV). Given the high accuracy the device can be used to improve current installations and create new network infrastructures of smart systems for seismic and structural monitoring, finalized to collapses prevention in critical structures, such as schools and hospitals, for creating shaking maps and for implementation of Earthquake Early Warning (EEW) system, based on Internet of Things architectures.

The project developed during the PhD period aims to design, develop, implement and verify an innovative system of sensors and algorithms of data processing, which makes it possible for an accurate survey and assessment of the main environmental and energy parameters in buildings.
The work has been included in the project SIMEA (Integrated/Distributed Energy Monitoring and Environmental), funded by the Region of Veneto in the "Strategic Plan for Scientific Research, Technological Development and Innovation 2008-2010".
The sensor system is designed to produce the energy/operating building profile to be used for:
- the purpose of certification of buildings;
- the process of energy audits to improve the working conditions and comfort;
- to promote the maximization of resources through an intelligent automatic control.
The theory concerning the energy efficiency of buildings is based on a compromise between comfort and consumption and, in fact, all the regulations are aimed to decrease (decrease) the power consumption without compromising the comfort of the internal environment in which people are living.
For this purpose, in the project of thesis have been considered, among others, UNI EN 15251:2007 which has the purpose to define which are the components to ensure the indoor comfort and UNI EN 15603:2008 which explains in detail the types of energy certifications. The sensor system developed is based on the latter regulation.
The technical literature presents several studies aimed at defining the effective energy assessment of the building and if it can be certified with a methodology based on performing calculations or measurements made in situ. It can be concluded that the procedures are not discriminating but complementary: methods of calculation are used for an assessment of the standard type, implemented by software tools, while the monitoring system are used for assessment of the real consumption.
The sensor system developed tries to satisfy the need to use a methodology based on monitoring the real behavior of building-plant but supported, for assessment of the energy consumption, by a calculation software validated at international level.
The hardware part of the monitoring system is formed by a series of sensors for the measurement of various thermohygrometric parameters and is divided into two networks that differ by type and objectives: the structure in the fixed network (wired) and the structure in the mobile network (wireless).
The development of the PhD project made it possible for monitoring with the system of sensors installed; this system permits not only the calculation of current consumption but also to define a short-term forecasts for the next day. In particular, the forecasts have been carried out in two modes:
- estimation of consumption with air conditioning on and the setpoint temperature;
- estimation of the temperature in free evolution with the conditioning system off.
The final part of the work was devoted to the validation of the predictions made and the use of the sensor network for other purposes that could expand the potential of the monitoring system developed.Il lavoro sviluppato nell’ambito del dottorato di ricerca ha l’obiettivo di progettare, sviluppare, realizzare e verificare un sistema innovativo di sensori, e relativi algoritmi di elaborazione dei dati, che permetta di effettuare una rilevazione e una valutazione precise dei principali parametri ambientali ed energetici negli edifici. Il progetto è stato inserito all’interno di un progetto sovvenzionato dalla Regione Veneto nell’ambito del “Piano strategico per la ricerca scientifica, lo sviluppo tecnologico e l'innovazione 2008-2010” denominato SIMEA (Sistema Integrato/distribuito di Monitoraggio Energetico ed Ambientale). La rete di sensori ha lo scopo di produrre il profilo energetico/operativo dell’edificio per essere successivamente utilizzato: - ai fini della certificazione, per elaborare degli audit energetici in modo da migliorare le condizioni operative e di comfort; - per incentivare l’utilizzo ottimizzato delle risorse attraverso un controllo automatico intelligente; - per ricavare informazioni utili alle procedure di manutenzione. La teoria riguardante l’energetica degli edifici si basa sul sottile compromesso tra comfort e consumi e, infatti, tutte le normative sono volte a cercare di abbassare i consumi non compromettendo il comfort dell’ambiente interno dentro cui le persone vivono. A questo scopo, nel lavoro di tesi sono state considerate, tra le altre, la norma UNI EN 15251:2007 che definisce quali sono le componenti per assicurare il comfort indoor e la UNI EN 15603:2008 che specifica le tipologie di certificazione energetica; ed è proprio a quest’ultima che si riferisce il sistema di sensori sviluppato. La letteratura tecnica presenta numerosi studi volti a definire l’effettiva valutazione energetica di un edificio e se questa possa essere certificata con una metodologia basata su esecuzione di calcoli oppure su misure eseguite in loco. Si può concludere che i procedimenti non sono discriminanti ma complementari: i metodi di calcolo servono per una valutazione di tipo standard, implementata spesso da strumenti software, mentre i monitoraggi sono utilizzati per una valutazione reale dei consumi. Il sistema di sensori sviluppato cerca di soddisfare l’esigenza di utilizzare una metodologia basata sullo sfruttamento dei monitoraggi per la valutazione ad hoc del comportamento reale edificio-impianto ma supportato, per la valutazione del consumo energetico, da un software di calcolo validato a livello internazionale. La parte hardware del sistema di monitoraggio è formata da una serie di sensori per la misura delle varie grandezze termoigrometriche ed è diviso in due reti che differiscono per tipologia e obiettivi: la struttura a rete fissa, cablata, e la struttura a rete mobile, wireless. Lo sviluppo del progetto di dottorato ha permesso di utilizzare i monitoraggi eseguiti con il sistema di sensori installato, non solo per il calcolo dei consumi attuali ma per realizzare anche delle previsioni a breve termine, ovvero per il giorno successivo. In particolare le previsioni effettuate sono state eseguite in due modalità: - stima dei consumi con impianto di climatizzazione acceso e temperatura di setpoint impostata; - stima della temperatura in evoluzione libera con impianto spento. La parte conclusiva del lavoro è stata dedicata alla validazione delle previsioni eseguite nonché all’utilizzo della rete di sensori per altri scopi che potessero ampliare le potenzialità della sistema di monitoraggio sviluppato.

Negli ultimi dieci anni si è rinnovata l’esigenza di sviluppare nuove tecnologie legate alla telemedicina, specie a seguito dello sviluppo dei sistemi di telecomunicazione che consentono ad ogni persona di avere a disposizione sistemi portatili, come gli smartphone, sempre connessi e pronti a comunicare. Lo stesso sviluppo si è avuto all’interno dei sistemi sanitari in cui è diventato fondamentale informatizzare le attività ospedaliere per via del contesto demografico a cui si va incontro: invecchiamento della popolazione e aumento del numero di pazienti affetti da malattie croniche. Tutti questi aspetti portano all’attuazione di un cambiamento strategico. Le Body Area Network, fulcro di questo lavoro di tesi, rappresentano la risposta a questa necessità. Si spiegano l'architettura e le tecnologie abilitanti per la realizzazione di queste reti di sensori, gli standard di comunicazione tramite i quali avviene la trasmissione dei dati e come le reti si interfacciano con i pazienti e le strutture sanitarie. Si conclude con una panoramica sui sensori di una BAN e alcuni esempi in commercio.

Researchers have been focused on the influences of flowing fluid on the corrosion of bare metals, but there is little emphasis on the degradation of metal-protective coating. Evaluating the metal-protective coating usually uses the Electrochemical Impedance Spectroscopy (EIS) method. EIS is a technique used for evaluating coating permeability or barrier performance based on the electrical impedance of coating. This paper presents a new impedance-based wireless sensor network for metal-protective coating evaluation. This wireless sensor network consists of two parts: impedance-based wireless sensor nodes and a wireless data base that are equipped with a network analyzer (AD5933) and a RF transceiver (CC1111/CC1110). In the experiment, there are three coating panels immersed in flowing deionized water (DI water) and one coating panel immersed in stationary DI water. Experimental results demonstrate that the proposed wireless sensor network is capable to evaluate the coating degrading.

This chapter extends application of a framework proposed by the authors (73, 74) for automated damage detection using strain measurements to study feasibility of using sensors that can measure accelerations, tilts, and displacements. The study utilized three-dimensional (3D) finite element models of double track, riveted, steel truss span, and girder bridge span under routine train loads. The chapter also includes three instrumentation schemes for each bridge span (65) to investigate the applicability of the framework to other bridge systems and sensor networks. Connection damage was simulated by reducing rotational spring stiffness at member ends and various responses were extracted for each damage scenario. The methodology utilizes Supervised Machine Learning to automatically determine damage location (DL) and intensity (DI). Simulated experiments showed that DLs and DIs were detected accurately for both spans with various structural responses and using different instrumentation plans.

With the needs for full structural state awareness and health monitoring as well as emerging challenges of Urban Air Mobility (UAV) and Future Vertical Lift (FVL), Health and Usage Monitoring systems (HUMS) need to be more accurate, robust and reliable than ever before. In active-sensing guided-wave networks in particular, conventional Damage Index (DI)-based approaches have been the industry standard for decades because of their computational simplicity and ability to do the damage detection and quantification tasks. However, under specific circumstances, like for specific actuator-sensor paths within a network or due to varying operational conditions, DIs can suffer from various drawbacks that make them prone to inaccurate and/or ineffective damage quantification. This study builds on previous work by the authors where DIs were used to train single-output Gaussian Process regression models (SOGPRMs) for robust damage quantification, and the accuracy limit of SOGPRMs was shown to depend on the evolution of the chosen DI formulation with damage size. In this study, multi-output GPRMs (MOGPRMs) are used instead in order to leverage information about damage size from multiple actuator-sensor path DI values. It is shown that the proposed approach can overcome the different shortcomings of DI evolution with damage size in the different path by capturing the correlation between the DI evolution for different paths. The proposed framework is applied for an Al coupon with simulated damage, and the damage size quantification results are compared with those of SOGPRMs. It is shown that the information fusion approach exhibited by MOGPRMs gives more accurate damage size estimations compared to SOGPRMs.

In this paper, a Guided Lamb Wave (GLW) technique using piezoelectric transducers is presented to detect and monitor corrosion damage in an aluminum panel. An electro-chemical etching method was applied to simulate corrosion damage in the test article. A signal processing approach using time-based analysis was demonstrated to measure amplitude change and phase shift of GLW signals captured in the aluminum specimen. Damage Index (DI) for each sensor network was calculated based on the time-domain signal processing method. From the DI information, damage profile maps were produced by using a tomographic algorithm. Corrosion damage location and its size were identified from an integrated damage profile map. The severity of the corrosion damage was examined based on the phase shift of a fundamental anti-symmetric mode (A0) in the GLW signals. The experimental results show the capability of the proposed corrosion monitoring technique based on the GLW approach.

Full textAbstract:
L’attuale momento di crisi sociale, ambientale e spaziale può essere una svolta - uno dei
significati della parola greca originaria κρίσις - del modello di sviluppo basato sul paradigma
industriale (Khun, 1962) i cui limiti erano ipotizzati nell’omonimo The Limits of Growth
commissionato dal Club di Roma ad alcuni ricercatori del MIT di Boston (USA) edito nel 1972. Il
presente scritto suggerisce di sostituire al modello industrialista del “fare la città” - indifferente
alle condizioni locali grazie alla supremazia data alle “soluzioni” tecnologiche (Del Nord,1991) -
l’approccio ecologico che parte dalle condizioni locali quali indicazioni di
piano/progetto/realizzazione per la trasformazione dell’anthropocosmo, cioè del rapporto tra
contenitori, reti e comportamenti, ovvero del λόγος, discorso, studio, con l’οίκος, ambiente
(www.ekistics.org) con le finalità di Smart City cioè costruire Comunità inclusive, sostenibili
socialmente e materialmente avendo il risparmio di consumo di suolo come presupposto della
sostenibilità. Ciò significa per i paesi ormai più che emergenti - BRIC e tutti gli altri in forte
crescita economica - evitare gli errori compiuti dalle nazioni, usualmente chiamate Occidentali,
di devastazione del territorio oltre che in termini di danni sociali. Mentre per quest’ultime
l’attenzione va posta al tema della riqualificazione dell’esistente sotto il profilo funzionale,
spaziale, ambientale e sociale. Per entrambe si pone la questione centrale del rapporto con la
storia, i segni di essa sul territorio, cioè la memoria quale essenziale componente del senso
delle cose. The current social, environmental and territorial crisis, can be a turning point - one among the
meanings of the originary Greek word κρίσις - of the development model based on the industrial
paradigm (Kuhn, 1962) whose limits were declared in the homonymous The Limits of Growth
commissioned by the Club of Rome at Boston MIT researchers (Meadows and al.) and
published in 1972. This paper suggests to replace the industrial model of “making the city” -
indifferent to local conditions thanks to the supremacy given to the technological “solutions” (Del
Nord, 1991) - with the ecological approach that starts from the local conditions such as
indications of plan/project/construction for the transformation of the anthropocosmo, i.e. the
relationship connecting shells, networks and behaviours. That is to relate the λόγος, discourse,
analyses, with the οίκος, the environment (www.ekistics.org): finally the purpose of Smart City. It
requires to build inclusive Communities, socially and materially sustainable, having the saving of
land use as precondition. This should mean for most countries now more then emerging - BRIC
and everyone else in the strong economic growth - try to avoid the mistakes made by the
nations, usually known as Western ones: i.e. devastation of the territory, social harms, and
attention to the spatial redevelopment, and to the functional and social ones. For both there is the central question of the relationship with history, the signs of it, ie the memory as essential
component of the meaning of things.

Full textAbstract:
Mobile Spatial coordinate Measuring System (MScMS) is a wireless-sensor-network based system developed at the Industrial Metrology and Quality Engineering Laboratory of DISPEA – Politecnico di Torino. It has been designed to perform simple and rapid indoor dimensional measurements of medium-large size objects (large scale metrology). It is made up of three basic parts: a “constellation” of wireless devices (Crickets), a mobile probe, and a PC to store and elaborate data. Crickets and mobile probe use ultrasound (US) transceivers in order to evaluate mutual distances. Each US device has a communication range limited by a cone of transmission within a nominal opening angle of about 170° and a maximum distance of no more than 8 m. The mobile probe location in the working volume is obtained by a trilateration, consequently it should communicate with at least 4 constellation devices at once. The system makes it possible to calculate the position — in terms of spatial coordinates — of the object points “touched” by the probe. Acquired data are then available for different types of elaboration (determination of distances, curves or surfaces of measured objects). During the system set-up, the constellation Crickets (beacons) are manually placed in the working volume (we define this operation as “positioning”). After that, their coordinates are determined as much precisely as possible (this operation is said “location”). The positioning of constellation devices is one of the most critical aspects in the system set-up. In principle, Crickets can be arranged without restrictions all around the measured object. However, the number and position of network devices are strongly related to the dimensions and shape of both the measuring volume and the measured object. The accuracy in the location of constellation devices is fundamental for the accuracy of the coordinates of the touched points during measurement operation. It is important to assure a full coverage of the space served by network devices by a proper alignment of US transmitters. For that reason, an ad hoc software “pre-processor” has been developed in order to help the operator in positioning and locating constellation devices in the working volume, according to the measuring space and the measured object dimensional characteristics. The aim of the paper is to introduce and describe this computer-assisted approach. Some preliminary results of experimental tests carried out on the system prototype are also presented and discussed.
