Traditional architecture and urban form is a harmonious and interrelated blend of social relations, cultural beliefs and religious principles forming coherent spatial organisation living in harmony despite diversity of religious beliefs, social class or cultural practices of different communities. The purpose of this paper is to discuss the theoretical background of social cohesion and solidarity in the everyday life of the Mahalla with reference to its religious background in Islam.

The study of Beit Hadawi and Beit Hammadi el-Hassan as distinct evidences of prominent families within the boundaries of Mahallat El Mahdia in Old Hilla offers an empirical investigation on how values of the past informed and, to some extent, governed the very organic organisation of interlocking residential units in Iraq.

It investigates the architecture of home and the spatial organisation of Mahalla’s social activities through highlighting the effect of previous factors in creating a responsive environment that sustained its operational mechanism and fluidity over centuries.

This paper examines how previous values, traditions and rituals are behind the organic tissue of traditional quarters and thus providing an effective criterion to be considered when discussing sustainable development or creating a responsive environment in societies with exceptional privacy.

Introduction: With the accelerated process of building metropolitans, more and more people tend to live in cities. So, to deal with this, the need has arisen to make smart everything that we have around us even when we arrived at the term of the smart city. All of this produces data we call big data that is generated by citizens.

Aim: So, cloud computing is the main idea implementation which we can use ineffective from all of these services which we call smart. And taking into account all of this, in this literature review, we have used different techniques to extract the most relevant papers on our topic. Mainly, we focus on smart cities and their taxonomy of it such as smart homes, smart buildings, traffic monitoring, security and emergencies, and so on. For a smart city, we discussed different proposed system architectures which represent the real work of researchers.

Results: In this way, we mention services that are offered and have the base services cloud services. Also, the articles we used are extracted and analysed from the most powerful and relevant databases such as IEEE, ACM, Elsevier, Science Direct, and so on. In total, we take 88 papers, and from all of these papers we have extracted 53 with different methods. This Systematic Literature Review presents building and using smart cities inside of cloud computing services.

Conclusion: However, a different implementation idea to do better life for all of us is by converting our lifestyle into a new form of living. The only form of implementation is by digitalising and implementing everything around us which means making every service in one place, where you can have access from anywhere, anytime. So, the smart city is the future.

Originality/value: This systematic literature review contributes to everyone who expresses interest to implement and provides additional evidence for existing studies in smart city patterns which used cloud services. Researchers offer various implementation forms of different models and express the impact of cloud services, especially for placements, where there are more people populated. Also, this study identifies a major weakness in existing smart city implementation by using cloud services, which have identified the main obstacles now and it needs to reanalyse the form of implementation for more complex systems in the future.

Coronavirus Disease 2019 (COVID-19) necessitated the need for “Hospital-at-home” improvisations that involve wearable technology to classify patients within households before visiting health institutions. Do-It-Yourself wearable devices allow for the collection of health data leading to the detection and/or prediction of the prevalence of the disease. The sensitive nature of health data requires safeguards to ensure patients’ privacy is not violated. The previous work utilized Hyperledger Fabric to verify transmitted data within Smart Homes, allowing for the possible implementation of legal restrictions through smart contracts in the future. This study aims to explore privacy-enhancing authentication schemes that are operated by multiple credential issuers and capable of integration into the Hyperledger ecosystem.

Design Science Research is the methodology that was used in this study. An architecture for ABC-privacy was developed and evaluated.

While the privacy-by-design architecture enhances data privacy through edge and fog computing architecture, there is a need to provide an additional privacy layer that limits the amount of data that patients disclose. Selective disclosure of credentials limits the number of information patients or devices divulge.

The evaluation of this study identified Coconut as the most suitable attribute-based credentials scheme for the Smart Homes Patients and Health Wearables use case Coconut user-centric architecture Hyperledger integration multi-party threshold authorities public and private attributes re-randomization and unlinkable revelation of selective attribute revelations.

This paper questions the change in patterns of use of the balcony during lockdown. It investigates whether residents, specifically of apartment buildings in Cairo, used their balconies more frequently or for different activities during the lockdown.

The study was conducted through a mixed methods approach. More specifically, a sequential explanatory design was adopted where quantitative data were collected at first followed by qualitative data collection. The study proceeded in two stages. First, an online questionnaire with 160 respondents was conducted to depict the change in the frequency and use patterns of balconies pre/post lockdown in Cairo. The respondents were approached through snowball sampling. Second, in-depth semi-structured interviews with 20 participants, approached through convenience sampling, were done. The interviews aimed to provide interpretation and rationale for the responses, patterns and correlations identified from the questionnaire results.

The findings of this study confirm that there is a change in the pattern of use of balconies in terms of frequency and the types of hosted activities. The analysis revealed three key ideas that characterize those changes: the balcony as a found space, as a loose space and as a space of self-expression at home. It also expands on spatial qualities of balconies that promoted their use. The study emphasizes the significance of such outdoor private spaces in apartment buildings and puts forward balconies as an essential element of future dwellings design for the multiple benefits they behold.

The originality of the study stems from tackling such a timely and unprecedented situation, where still few studies investigating the relationship between pandemic and the architecture of homes have been conducted. Furthermore, this study focuses particularly on exploring the use of balconies in Cairo, one of the largest cities in both Africa and the Middle East, during lockdown. Its findings might ultimately help formulate, define and characterize new trends in the architecture of homes that would embrace human needs in times of prosperity and rising tensions alike.

The dynamics of globalisation as the increasing interconnectedness between all aspects of social, cultural, economic, and political spaces have seen an unprecedented focus on migrants across the world. Far less discussed though has been the connections between spaces and places during migration - how conceptualisations of proximity/distance, inside/outside; native/migrant; past/present; memories/experiences produce and shape buildings, streets, and urban environments. While it is suggested that the unprecedented movement of people in a globalising world will be particularly significant for cities and urban life, it is also argued that such movement has led to a problematisation of ‘home’ as a particular type of built form in a physical location. This special issue is therefore interested in making the links between three important processes in a globalising world-home, migration, and the city - and their significance for built forms and built environments across the world.

Security is the most important issue in Internet of Things (IoT)-based smart cities and blockchain (BC). So, the present paper aims to detect and organize the literature regarding security in the IoT-based smart cities and BC context. It also proposes an agenda for future research. Therefore, the authors did a statistical review of security in IoT and BC in smart cities. The present investigation aims to determine the principal challenges and disturbances in IoT because of the BC adoption, the central BC applications in IoT-based smart cities and the BC future in IoT-based smart cities.

IoT) has a notable influence on modernizing and transforming the society and industry for knowledge digitizing. Therefore, it may be perceived and operated in real time. The IoT is undergoing exponential development in industry and investigation. Still, it contains some security and privacy susceptibilities. Naturally, the research community pays attention to the security and privacy of the IoT. Also, the academic community has put a significant focus on BC as a new security project. In the present paper, the significant mechanisms and investigations in BC ground have been checked out systematically because of the significance of security in the IoT and BC in smart cities. Electronic databases were used to search for keywords. Totally, based on different filters, 131 papers have been gained, and 17 related articles have been obtained and analyzed. The security mechanisms of BC in IoT-based smart cities have been ranked into three main categories as follows, smart health care, smart home and smart agriculture.

The findings showed that BC’s distinctive technical aspects might impressively find a solution for privacy and security problems encountering the IoT-based smart cities development. They also supply distributed storage, transparency, trust and other IoT support to form a valid, impressive and secure distributed IoT network and provide a beneficial guarantee for IoT-based smart city users’ security and privacy.

The present investigation aims to be comprehensive, but some restrictions were also observed. Owing to the use of some filters for selecting the original papers, some complete works may be excluded. Besides, inspecting the total investigations on the security topic in BC and the IoT-based smart cities is infeasible. Albeit, the authors attempt to introduce a complete inspection of the security challenges in BC and the IoT-based smart cities. BC includes significant progress and innovation in the IoT-based smart cities’ security domain as new technology. Still, it contains some deficiencies as well. Investigators actively encounter the challenges and bring up persistent innovation and inspection of related technologies in the vision of the issues available in diverse application scenarios.

The use of BC technology in finding a solution for the security issues of the IoT-based smart cities is a research hotspot. There is numerable literature with data and theoretical support despite the suggestion of numerous relevant opinions. Therefore, this paper offers insights into how findings may guide practitioners and researchers in developing appropriate security systems dependent upon the features of IoT-based smart city systems and BC. This paper may also stimulate further investigation on the challenge of security in BC and IoT-based smart cities. The outcomes will be of great value for scholars and may supply sights into future investigation grounds in the present field.

As the authors state according to their knowledge, it is the first work using security challenges on BC and IoT-based smart cities. The literature review shows that few papers discuss how solving security issues in the IoT-based smart cities can benefit from the BC. The investigation suggests a literature review on the topic, recommending some thoughts on using security tools in the IoT-based smart cities. The present investigation helps organizations plan to integrate IoT and BC to detect the areas to focus. It also assists in better resource planning for the successful execution of smart technologies in their supply chains.

The purpose of this paper is to develop a comprehensive research model that can explain potential customers’ behavioral intentions to adopt and use smart home services.

This study proposes and validates a new theoretical model that extends the theory of planned behavior. Partial least squares analysis is employed to test the research model and corresponding hypotheses on data collected from 216 survey samples.

Mobility, security/privacy risk, and trust in the service provider are important factors affecting the adoption of smart home services.

To increase potential users’ adoption rate, service providers should focus on developing mobility-related services that enable people to access smart home services while on the move using mobile devices via control and monitoring functions.

This study is the first empirical attempt to examine user acceptance of smart home services, as most of the prior literature has concerned technical features.

A brief review is provided as to the growth of home banking in the UK in general and in Scotland in particular. Some attention is paid to a comparison in the services provided by two leading home banking systems and a speculative extrapolation is made as to how developments in home banking may proceed into the future.

Smart homes are recent Internet of Things applications that aim to improve residents’ quality of life. Despite its potential, the adoption of smart homes, in general, and its devices and appliances, in specific, is not reaching a mass market yet. This study aims to investigate the factors that influence residents’ intention to buy smart homes devices in Jordan.

This paper proposes a novel model to study users’ intention to buy smart homes devices by following a quantitative method. Responses were collected and statistically analyzed from 375 households using structural equation modeling.

Results show that user awareness, perceived cost, perceived enjoyment, personalization, user trust and social influences significantly influence the intention to buy smart home devices.

To the best of the authors’ knowledge, this paper is the first study attempts to predict intention to buy smart home devices in Jordan. The findings provide meaningful implications for smart home devices providers.

This paper aims to expose the direct and indirect impacts of changing culture and society principles on the built environment, architectural scene and practice. Studying culture-architecture forceful formula in present-day Iraq, as not previously discussed, reveals how cultural shift affects the public image of architectural form, uses and activity system, thus how latter issues highlight or predict society deterioration or collapse.

Comparing and analysing past and contemporary works, highlighting strange values emerged later, personal survey and observing house forms, in-depth interviews, photos and architectural drawings are a set of methodological tools used in approaching research main objective.

Findings include two mutual systematic approaches. The first is to define, acknowledge and understand previous criteria, while the second is to disclose responsible authorities and institutions and their role in addition to necessary procedures to correct or minimize the impact of various changes on the contemporary architectural situation.

Contemporary Iraqi society and culture have been dealt with as distorted and destructive, where various unacceptable values describe its current image compared to the noble form of the inherited. As a true expression and a visible manifestation of culture with which it interacts, degraded architecture and urbanism in contemporary Iraq provide an accurate picture of the current state of society, its values, principles and beliefs.
