Intelligent Municipal Heritage Management Service in a Smart City: Telecommunication Traffic Characterization and Quality of Service

Abstract

The monitoring of cultural heritage is becoming common in cities to provide heritage preservation and prevent vandalism. Using sensors and video cameras for this task implies the need to transmit information. In this paper, the teletraffic that cameras and sensors generate is characterized and the transmissions' influence on the municipal communications network is evaluated. Then, we propose models for telecommunication traffic sources in an intelligent municipal heritage management service inside a smart sustainable city. The sources were simulated in a smart city scenario to find the proper quality of service (QoS) parameters for the communication network, using Valencia City as background. Specific sensors for intelligent municipal heritage management were selected and four telecommunication traffic sources were modelled according to real-life requirements and sensors datasheet. Different simulations were performed to find the proper CIR (Committed Information Rate) and PIR (Peak Information Rate) values and to study the effects of limited bandwidth networks. Packet loss, throughput, delay, and jitter were used to evaluate the network's performance. Consequently, the result was the selection of the minimum values for PIR and CIR that ensured QoS and thus optimized the traffic telecommunication costs associated with an intelligent municipal heritage management service.A fundamental aspect in smart cities is the municipal communication network that allows the transmission of the information from different devices. Several kinds of devices are transmitting information in a smart city, from small sensors of noise, pollution, temperature, parking, etc. to video cameras, apart from voice communications systems. The mathematical characterization of the aggregate traffic, generated by these numerous and different sources, is complex and simulation techniques are useful to perform the evaluation [7]. This work is based on an existing municipal network architecture and evaluates the communications needs for the deployment of a new service [8]. The new service evaluated is the intelligent management of the city cultural heritage [9].Cultural heritages are important treasures for cities from the touristic point of view. Besides, citizens are also willing to preserve the symbols of their own history. The intelligent

A Decade Review on Smart Cities: Paradigms, Challenges and Opportunities

“…Smart cities use technology for improved organization while improving the sustainability of natural resources. The smart city's SI includes intellectual capital, human capital, and quality of life [97] [98]. Public responsiveness, accountability, and promise play a vital part in promoting the smart city concept.…”

Social Dimensions of Spatial Justice in the Use of the Public Transport System in Thessaloniki, Greece

“…Cities must be redesigned once again to be able to meet the need for more open spaces, greenery, athletic activities, and especially the social distance that proved vital during the time of global quarantine. Hence, new forms of urban planning, including concepts of the resilient city and the city based on a circular economy, have appeared, and these concepts are reshaping older ideas of sustainable cities [12][13][14]. However, one issue still prevails: how can all these urban policies and practices change the living environment of all urban dwellers?…”
