Periodic Reporting for period 1 - SCENE (Smart City on the Edge Network Enhancements)

Teaser

Summary

SCENE is a novel concept of a secure mobile IoT platform for smart city applications based on vehicular networks and targeting at mid-sized municipalities. It offers synergies among public projects and decreases costs of smart city initiatives.

There are several major economic barriers to the widespread adoption of smart city services. Among them: large infrastructure expenditures and unpreparedness of local public institutions to handle new approaches to city governance. To address the challenge of inventing smart city solutions suitable to small and mid-sized cities, the SCENE project aims to lower the infrastructural cost of smart city deployment by providing an open platform upon which smart city operators, municipalities and sensor providers can cooperate to develop innovative smart city services that provide benefits to the society, including lower pollution, safer streets and more efficient municipality services.

SCENE consists of intelligent gateways embarked on vehicles that integrate content delivery and sensors information collection/processing and a service platform that implements additional processing logic, manages the intelligent gateways and interacts with external services like smart city applications and access networks. SCENE is built on top of a solution for content delivery in transport, developed in a Eurostars program.

The overall objectives of SCENE are:

1. Design and implementation of an integrated IoT platform for smart city applications
a) Definition of the underlying system infrastructure architecture and communication protocols;

b) Implementation of application layer structure/interfaces;

c) Compatibility of both mobile content delivery and IoT based services;

d) Security framework for both content delivery and IoT;

e) Management framework.

2. System integration and â€œLiving Labâ€ pilot â€“ SCENE Living lab objective is to benefit from the ecoystem prior and during the field trial for co-creation of new ideas, scenarios and business models. Innovative ideas/scenarios will be explored by the multidisciplinary teams of partners, potential customers and other stakeholders prior to the field trials. Selected scenarios and implemented services will be examined and evaluated during the field trial with high level of agility.

Work performed

During the first year of the project, work was focused on developing and integrating the several parts of the SCENE platform. To this end, the consortium defined three use cases to be tested in the first phase of pilots, due to the beginning of the second year of the project. The use cases were carefully designed to test all aspects of the platform, based on the overall objectives defined at the beginning of the project.
The Italian use case is based on monitoring of critical infrastructures. The pilot involves the mobility of the gateway (mounted in AMT buses) and the usage of two different sensors, one set of â€œsmart sensorâ€ based on Raspberry Pi using WiFi to connect to the mobile gateway and a set of of-the-shelf commercial sensors that connect to the gateway using Bluetooth Low Energy (BLE). This use case demonstrates the usage of different types of sensors to set up a sensor network to monitor temperature and vibration in historical buildings. Regardless of the source of the data, the SCENE platform is able to capture this information and record it in its Service Platform, to be used by specialized applications.
The Italian use case will also allow us to test and demonstrate the content delivery platform to be used within AMT buses by the public.
The Portuguese use case is based on the detection of parking infractions. To this end a specialized sensor prototype was developed, that uses edge computing and artificial intelligence to detect double-parked cars. This use case will push the limits of the SCENE vehicular network by using data that is based on high resolution photographic evidence, with file sizes rounding the hundreds of KB. This use case will thus demonstrate that the SCENE framework can be used for situations where traditional IoT communication solutions are inadequate, by using public transportation as a means to effectively bring these large files from sensor to the Service Platform.
Regarding ethics and privacy, the Portuguese use case was also chosen to demonstrate how it is possible to implement smart traffic monitoring solutions without compromising the rights of the citizens. The use case was subjected to a formal Data Protection Impact Assessment, that resulted in the implementation of several privacy and security controls into the system.
The final French use case will demonstrate the possibility of mounting sensors in the public transport, using it as a way to monitor air pollution levels within the whole city. This will allow a better map of pollution â€œhot spotsâ€ where targeted action by the municipality will lead to a better environment for the citizens.
At the end of RP1, all the components have been tested in laboratory, and the integration has been demonstrated from sensor data to Service Platform.

Final results

The SCENE Project is pushing the boundaries of IoT sensor networks. By decoupling the sensor from the user application, a platform is created that allows for new innovative solutions to be deployed in smart cities. Sensor manufacturers can develop advanced solutions that are not constrained by the available bandwidth and communicate using standard low-range protocols such as BLE and 802.11 WiFi, and can focus on smart detection of events, using machine learning and on-the-edge computing. On the other hand, smart city operators and application developers can focus on the development of specialized user applications that work on top of the Service Platform, using the data produced by the sensors, but without concern regarding the management of the sensor network.
One of the several innovative aspects of SCENE Platform is to realize a â€œon the moveâ€ IoT / Content dynamic infrastructure, able to reach even remote areas not possible to be covered by affordable infrastructures.
In addition, SCENE will be able to provide to its clients the possibility to run inside the Intelligent Gateways their own applications, enabling an affordable On The Edge processing service.
In addition, SCENE enables usage of low cost and low range wireless sensors that can stimulate even small companies to create valuable Smart city Services.

Until the end of the project, the SCENE platform will be prepared to integrate with new solutions beyond the three use cases demonstrated during the project. This will permit the creation of a marketplace for new sensors, new smart-city applications and services.
The wider societal implications of this project include the creation of opportunities for IoT sensor startups and the creation of beneficial services for small and mid-sized cities across Europe.
