Systematic literature review of context-awareness applications supported by smart cities’ infrastructures

Abstract

Since none of the existing systematic reviews of the literature related to smart cities have focused on smart cities applications using context-aware features, this study aims to provide a comprehensive view of (1) the characteristics of context-aware applications supported by smart cities’ infrastructures, (2) the characteristics of the context-aware technologies being used, and (3) the maturity level of the identified applications. An electronic search was conducted on Scopus, Web of Science, and IEEE Xplore databases, combining relevant keywords. After the studies’ selection, 27 studies were included. The results show the interest in using context-aware features to develop smart cities’ applications targeting public health, tourism experience, urban mobility, active citizenship, shopping experience, management of urban infrastructures, public alerts, recommenders, and smart environments. Moreover, the applications reported by the included studies do not allow the execution of actions without the explicit consent of the users, and they integrate personal sensors, sensors deployed in the city and crowdsourcing mechanisms to acquire primary context attributes (i.e., location, activity, and environment) and secondary context attributes (i.e., speed, physical activity, points of interest, stress, and tourists’ emotions). In addition, the included studies present scarce details about context reasoning, data privacy, integrity, and confidentiality, data aggregation and accuracy, and data interoperability. Finally, the results also indicate low maturity level of the developed applications, which is evidenced by the lack of user-centred evaluations, as well as by the difficulty in integrating important technologies being developed for smart cities.

A Comprehensive Survey of Context-Aware Continuous Implicit Authentication in Online Learning Environments

“…Context-aware continuous authentication systems include dynamic operating environments in the literature in relation to the biometric authenticator they have chosen. Regardless of the type of authenticator used, all the included studies have considered a passive context-awareness approachthe system constantly observes the environment or user activity in order to offer the appropriate options to the user [63]. The system monitors users' activities in online learning platforms to utilise the best authenticator to identify the user without interrupting their activities.…”

Where Are Smart Cities Heading? A Meta-Review and Guidelines for Future Research

“…However, the average CASP score (Table A2) is 16 pts, which means the overall quality is good (on a 4-level scale: excellent, good, moderate, poor). Only 24% of the articles scored excellent [27][28][29][30][31][32][33], 60% good and 17% of moderate quality. Most of the generally high-scoring reviews (i.e., ≥16%) published in Q1 journals focused primarily on topics such as smart cities dimensions [27,29], digital transformation [31,32], sustainability [30,32,[34][35][36][37] and resilience [30,38,39].…”

SWOT analysis of green building systems in real estate development

“…As a result of the strategic combination of sustainability, smart cities and technology, sustainable development (energy efficiency, pollution, resources), citizen welfare (public security, education, health, social care), and economic development (investment, business, innovation) are provided [11]. Smart city and sustainable development policies and goals should be based on smart industries and services (smart energy, water, transportation, buildings, and government) and be supported by smart infrastructure (sensor networks, data analytics, smart devices, control systems, communication platforms, web).…”
