Final Meeting, 3-5 June 2019, London

Regional Statistical Office – Severoiztok

is one of the 6 divisions of the National Statistical Institute. Its activity is focused in several directions:

• Implemented state policy in the field of statistics; • Performed statistical data collection for all surveys in any areas of

statistics; • Collect, process and analyze statistical information based on

established methodologies and methods for conducting statistical surveys included in the National Program as well as by requests from external users;

Description Varna Limitless – building an IoT system in Varna for bettering the infrastructure and getting statistical data.

Final Meeting, 3-5 June 2019, London

Why Varna is a smart city? • A ”smart city” is an urban area that uses different

types of electronic data collection sensors to supply information which is used to manage assets and resources efficiently.

• This includes data collected from citizens, devices, and assets that is processed and analyzed to monitor and manage traffic and transportation systems, power plants, water supply networks, waste management, law enforcement, information systems, schools, libraries, hospitals, and other community services.

Key Drivers for IoT Applications in SC Key Drivers for IoT Applications in Smart Cities: Cost - wireless solutions are much cheaper to install and maintain than landlines. Efficiency - wireless solutions enable remote monitoring and management of IoT deployments. Resource reduction - IoT applications can make it possible to use sensors to gather data and wireless modules to control resource use, which can result in a dramatic reduction in resource use.

DLT infrastructure example1 example2 • A distributed ledger is essentially an asset database

that can be shared across a network of multiple sites, geographies or institutions.

• All participants within a network can have their own identical copy of the ledger.

• Any changes to the ledger are reflected in all copies in minutes, or in some cases, seconds. The assets can be financial, legal, physical or electronic.

DLT infrastructure

Final Meeting, 3-5 June 2019, London

Benefits of DLT in IoT Applications Security - Centralized networks create a single point of failure for all connected services, while devices on a distributed network are more autonomous and not reliant on a core system. Device Management - Utilizing a distributed architecture with DLT that enables devices to communicate directly with each other will enhance the capabilities of device management.

Benefits of DLT in IoT Applications Cost Savings - By operating in a shared P2P economy, as changes to the database are processed, each participant node on an IoT network uses its own processing power to validate each request. Reduced Connectivity Bottlenecks - While the server-client model of IoT may currently suffice, the volume of data being collected and transmitted in the future might outpace a centralized service’s ability to process it.

Benefits of DLT in IoT Applications Smart Contracts - DLT benefits IoT solutions that rely on smart contracts. Smart contracts are a computation protocol that, when predefined conditions are met, automatically carry out a specified action between connected applications. Audit Trails - One of the main benefits of DLT is the immutability of its ledger and the ability, therefore, to audit all events in the ledger. Changes to the ledger that have been successfully authenticated cannot be deleted or modified.

Benefits of DLT in IoT Applications Data Reliability - For organizations using IoT solutions to collect and analyze key performance indicators (KPIs) that require enhanced security, DLT is an obvious benefit. As changes to a distributed database are required to undergo multiple levels of DLT validation, the risk of inaccurate or junk data being consumed for analytics is greatly reduced.

Final Meeting, 3-5 June 2019, London

Existing DLT infrastructure in Varna • There are 5 working nodes that run Hyperledger,

Etherium and EOS especially for Varna based projects.

• They are distributed between 5 different entities in order to provide secure distribution and publicity of all data.

• All nodes are publicly open and everyone can use them to run a project for a Smartcity based in Varna area.

Final Meeting, 3-5 June 2019, London

Existing DLT infrastructure in Varna • Both LoRaWAN and DLT are essential for the future

of IoT projects for Smartcity in Varna. • They provide a secure and open way to run

different projects that can benefit from their KPIs. They are the backbone of the planned IoT infrastructure. In this moment they provide enough capacity for all type of pilot projects.

• All data are open and can be used and reused from all local businesses and organizations.

Final Meeting, 3-5 June 2019, London

• Everyday life of disabled people in our society is full

of challenges that they have to overcome in order to function as normal members of the community.

• Unfortunately the level of public infrastructure in Bulgaria does not allow this.

• Moving even in a big city like Varna and access to a number of buildings is very difficult.

Varna Limitless project

Final Meeting, 3-5 June 2019, London

• A mobile application which monitors the movement of different groups of users with different disabilities and compare them with the movement of a control group of users without disabilities.

• Identify the problem areas as well as the movement patterns for each group and compare the differences.

• Personalized polls will be sent to individual users to gather detailed information about the issues people are experiencing at the detected problem areas.

Implementation of the project • Initial tests passed successfully. • LoRaWAN and beacons successfully installed and

tested. • Mobile APP transmitted and save data in the

private Etherium network set for the project. • Both user groups are selected – 10 disabled people

(all of them with partial loss of their movement) and a control group of 10 people without disabilities.

Final Meeting, 3-5 June 2019, London

Expected data for statistical purposes • Common spots visited by citizens in Varna; • Average number of visits to certain spots and places; • Average speed of movement through the city of people

without disabilities; • Average speed of movement through the city of people with

certain disabilities; • Difference of the average speed between both groups; • Average time spent in movement through the city;
