“…Multiple applications could benefit from a flexible payment system, from P2P distributed storage schemes, where users could hire local disk space for an economical incentive, to more sophisticated scenarios, like mobile crowdsensing [50]. Mobile crowdsensing (MCS) is a distributed application where the power of the crowd, jointly with the sensing capabilities of smartphones they wear, provides a powerful tool for data sensing, especially in those scenarios involving user behavior or those that rely on user mobility, where standard sensor networks may not be suitable.…”

P2P networks are the mechanism used by cryptocurrencies to disseminate system information while keeping the whole system as much decentralized as possible. Cryptocurrency P2P networks have new characteristics that propose new challenges and avoid some problems of existing P2P networks. By characterizing the most relevant cryptocurrency network, Bitcoin, we provide details on different properties of cryptocurrency networks and their similarities and differences with standard P2P network paradigms. Our study allows us to conclude that cryptocurrency networks present a new paradigm of P2P networks due to the mechanisms they use to achieve high resilience and security. With this new paradigm, interesting research lines can be further developed, both in the focused field of P2P cryptocurrency networks and also when such networks are combined with other distributed scenarios.

“…An updated review and a comparison of a selection of them is reported in [39][40][41]. Moreover, an extensive survey [42] shows evidence that there is still much heterogeneity in terms of technologies applied and deployment approaches, although modular designs at both client and server elements seem to be dominant. The Android mobile operating system is the most diffuse client platform, while server platforms are typically web-based, and client-server communications mostly rely on XML or JSON over HTTP.…”

The urban environmental planning, a fundamental dynamic process for cities’ sustainability, could benefit from the soundscape approach, dealing with the perception of the acoustic environment in which sound is considered as a resource rather than a waste (noise). Noise and soundscape maps are useful tools for planning mitigation actions and for communication with citizens. Both mappings can benefit from crowdsourcing and participatory sound monitoring that has been made possible due to the large use of internet connections and mobile devices with dedicated apps. This paper is a “scoping review” to provide an overview of the potential, benefits, and drawbacks of participatory noise monitoring in noise and soundscape mapping applications, while also referring to metrological aspects. Gathering perceptual data on soundscapes by using digital questionnaires will likely be more commonly used than printed questionnaires; thus, the main differences between the experimental protocols concern the measurement of acoustic data. The authors propose to classify experimental protocols for in-field soundscape surveys into three types (GUIDE, MONITOR, and SMART) to be selected according to the survey’s objectives and the territorial extension. The main future developments are expected to be related to progress in smartphone hardware and software, to the growth of social networks data analysis, as well as to the implementation of machine learning techniques.

“…In addition to traditional personal sensing systems, i.e. applications where a single device is involved, innovative mobile crowdsensing applications have been introduced [33][34] [193]. In crowdsensing applications many smartphone users acquire data that are sent to a cloud server where are processed and the results released to the public in the form of aggregated data and statistics, for example using social networks.…”

Modern mobile phones, featuring high performance microprocessors, rich set of sensors and internet connectivity are largely diffused all over the world and are ideal devices for the development of low-cost sensing systems, in particular for low-income developing countries and rural areas that lack the access to diagnostic laboratories and expensive instrumentation. In the design of a smartphone based sensing system different elements must be taken in consideration such as sensors performance, acquisition rate and privacy preserving strategies when personal data must be shared in the cloud. In this paper a sensor-centric survey on smartphone based sensing systems is presented, covering different fields of application. Two different development approaches will be discussed: 1) the exploitation of the large number of sensors embedded in modern smartphones (high-resolution camera, microphone, accelerometer, gyroscope, magnetometer, GPS); 2) the interfacing with external sensors that communicate with the smartphone by the embedded wireless or wired communication technology.
