In only a few ten years payment systems have undergone an incredible evolution passing from a physical transfer of cash to transactions exchanging money as digital data. Mobile Payment (m-payment) refers to one type of electronic payment, performed through mobile devices, such as mobile phones, smartphones, and tablets. To ensure trust and avoid frauds severe security requirements must be imposed. In addition, interoperability and privacy requirements, as well as speed of execution and ease-of-use are mandatory requirements, too. Several technical solutions have been proposed, associated to generally incompatible business models. From the end-users point of view, the result of a m-payment transaction is just one transfer of money from customer to merchant. However, to get this simple result, m-payments use a plethora of sophisticated technologies, including SMS, NFC, high-frequency sound waves, software apps. The heterogeneity of m-payment systems and economic models is an important challenge for their diffusion in the next years. Having described the main requirements, technical characteristics and different business models of m-payment, this paper underlines relationship of technological and business approach to m-payment systems.

In this work, we have implemented a data recovery software integrating the most recent rateless codes, i.e., RaptorQ codes. Thanks to the above-mentioned software, it is possible to recover data loss occurring on several kinds of network conditions. We have performed a statistical analysis of failure probabilities at several configurations of RaptorQ parameters. We have found a good agreement with the theoretical values of a random linear fountain code over Galois Field GF(256). Moreover, we have shown that the probability of having a certain number of failed decoded source blocks - when sending a fixed-size file - follows a Poisson distribution.

In recent years, the monitoring of End-to-End protocols from inside the mobile data network has become a powerful tool to gain insight into subscriber specific information on usage behavior and quality of experience. With the advent of big data in mobile networks, the power of statistical data analysis can now be utilized in order to answer so far untreatable questions both in the area of network operations and customer experience management. In order to make full advantage of the capabilities, an open framework is needed which allows the flexible and problem-driven design of solutions. This implies monitoring products to change from out-of-the box solutions towards tools enabling problem-related measurement design which should be supported by appropriate standards which are seen to come in the context of network function virtualization.

Mobile infrastructure and in particular radio access network (RAN) sharing is becoming an important topic that mobile network operators are evaluating and considering in their expansion plans and investments decision. The arguments for network sharing are well known. It can substantially reduce CAPEX and OPEX, potentially increase the speed of network rollouts, improve coverage and help meet the capacity demands of increased data traffic. However, such projects are very complex and require significant alignment and commitment between operators that typically compete. This paper shares experiences and suggestions from one of the first consolidation project at this scale in Europe between Orange and T-Mobile Poland.

The Web of Things is an active research field which aims at promoting Web standards and technologies adoption for handling smart things digital representations. In this context, many studies acknowledge that REST paradigm plays a decisive role, and this has prompted the emergence of systems for Web representation and management of real-world objects. However, objects exposure is only a first step. In fact, it is very likely that a client that exploits these representations to retrieve data from objects, also needs to process them. Typically, this processing is performed by an application which, in addition, has the burden of results exposure. In a data reuse perspective, these results are valuable: will they be re-exposed? If so, will they be exposed in a way enabling easy reuse? In this paper we present a graph model for RESTful publishing of Web resources in a WoT scenario and its implementation through the InterDataNet middleware. This graph model supports the definition of scriptable vertexes for processing other resources information. In this way, the paradigm is subverted: there is no need to set up an application to process smart objects information since the processing is externalized in a vertex of the resource model. Consequently, the RESTful exposure of results is utterly borne by the middleware. We also introduce an extension of the model to support event-driven capabilities.

We present a software tool able to help planning and deployment of wireless sensor networks (WSN) in an outdoor environment. The tool is based on a ray-tracing algorithm for the evaluation of electromagnetic propagation in a built-up area, and on additional software modules that use the output of the electromagnetic solver to generate nodes' connectivity matrix, to compute individual nodes' coverage areas, and to identify the best locations where gateways can be placed. The presented tool is able to deal with the radio-frequency propagation issues involved in WSN planning and deployment, and it is conceived as a part of an overall WSN deployment, planning, and commissioning & maintenance tool that is being developed in the framework of a European project.

Latest technological developments have allowed a more efficient use of the frequency spectrum, providing resources for the deployment of fourth generation broadband mobile networks, named LTE, in a portion of UHF band previously allocated to TV broadcasting. However, to cope with this new scenario, the designing criteria of the TV receiving installations need to be reviewed as well as, for existing installations, the problems of coexistence must to be addressed carefully. Accordingly, this study focuses on laboratory results of experimental tests carried out to evaluate interference effects occurring on DVB-T channels and in presence of different MATV configurations, due to radio emissions generated by LTE Base Stations in the 800 MHz band.

The ever increasing need to be able to take advantage of broadband services without the need to increase the electromagnetic pollution, has led the scientific community, in recent years, to look for alternatives to the use of a radio frequency communication. From this, it stems the need of budding paradigm of visible light communications. In the context of the activities of the IEEE 802.15.7 Task Group, a new modulation format named Color Shift Keying (CSK), based on sending signals spaced in the domain of the wavelength able to both support the communication and the illumination of indoor environments has been tackled. In this paper, a transmission scheme based on the use of the CSK modulation which also makes use of a modulation format that descends from the Pulse Position Modulation (PPM) has been proposed. The aim of this contribution is also proposing the receiver architecture for that kind of transmission and then evaluate its performance in terms of Bit Error Rate (BER) of Transmission Rate by performing also comparisons with the literature. The proposed scheme is robust with respect to optical interference and presents high rate and low BER at the cost of a bit complexity increasing with respect to other approaches.

Ground-Based SAR (GB-SAR) sensors are showing to be very useful in the topographic mapping. In this context, the phase unwrapping step plays a key role in the height recover. In the recent years, multi-channel Interferometric SAR (InSAR) techniques have proved to be effective in solving the phase unwrapping problem. Maximum Likelihood (ML) and Maximum a Posteriori (MAP) based approaches exploit statistical characterization in order to correctly combine the multi-channel acquisitions and to provide the three dimensional reconstructions of the observed scene. In this paper the application of the two estimation methods on a multi-channel GB-SAR configuration for the reconstruction of the topographic profile is analyzed. The potentialities of the techniques have been assessed by using a real data set.
