Today, many countries are institutionalizing the concept of smart city and implementing IoT programs that support smart city components, relying on the extensive IT infrastructure to improve the sustainability and quality of life needed by their communities. But using the Internet of Things to develop a smart city faces several challenges. Accordingly, the purpose of this study is to identify the main challenges of the Internet of Things and to understand the relationship between these challenges to support the development of smart cities in Iran. Initially, 14 major challenges were extracted based on domestic and foreign literature. Then, using the SWARA technique, the challenges were prioritized based on summarizing the views of seven relevant experts in the field of smart cities in Iran. In the next step, the underlying interactions between the identification challenges and their importance were determined using interpretive structural modeling (ISM). Then, MICMAC method was used to confirm the results. According to the findings, the challenges in the interpretive structural method were leveled at six levels. Then, to test the results of this stage, MICMAC method was used.The results of this stage showed that the lack of policies, perspectives and regulatory guidelines, high training, operational and maintenance costs, inequality (social), lack of transparency and responsibility, lack of technical knowledge among Planners, lack of technology infrastructure and lack of intelligence were identified as influential and key variables of the study.

Development of radio frequency spectrum based technologies and increasing demand with inefficient use of spectrum, in the near future will cause scarcity in relation to spectrum as a limited and valuable source. By using cognitive radio technology will transform the traditional spectrum management to the dynamic and more efficient one. The pioneer regulators have been starting activities inoptimization of spectrum usage and dynamic spectrum management. In this study we proposed the following two scenarios:"Hierarchical allocation of spectrum" and "secondary spectrum market" with their strengths/ weaknesses/ opportunities/ threats. The results show that in "Hierarchical allocation of spectrum" scenario there are considerable strength points for “Communications Regulatory Authority”to apply cognitive radio technology, while according to external threats, diversity could be the best strategy. But in "secondary spectrum market" due to existing Strengths and opportunities the best strategy would be attack or outrider position

In recent years, a number of new payment solutions have been introduced in mobile commerce although with less success. The existence of standardized and widely accepted mobile payment (also known as MP) procedures is crucial for successful business-to-customer mobile commerce. On the other hand, Non-acceptance of innovations has generally been attributed to the failure of laggards to keep up with the time. While our previous survey has investigated positive adoption decisions, this paper focuses on consumer resistance against innovation instead. In this paper we examine the conditions of resistance to the MP procedures by Iranian customers. In fact we attempts to discover causes that force an Iranian customer in particular to resist to innovation such as mobile payment. Based on the theory of innovation resistance and the mobile payment literature, we designed a questionnaire which is distributed amongst our understudy society of Ordinary Iranians. We employed data mining techniques in order to extract useful patterns from data, which describe the reasons of that refusal associated with different social and cultural levels of the society.
