Cloud computing translates the computing resources to a third party, eliminating the need to purchase, configure and maintain those resources. With the increasingly ubiquitous nature of Social networks and Cloud computing, users are starting to explore new ways to interact with, and exploit these developing paradigms. Social networks are used to reflect real world relationships that allow users to share information and form connections between one another, essentially creating dynamic Virtual Organizations. Cloud Computing and Social Network Sites (SNS) are among the most controversially discussed developments in recent years. The opportunities of using powerful computing resources on demand via the web are considered as a possible driver for the growth of the world economy. Social networks provide a virtual place where people can interact and share. With the increasing user base and the competition social networks needed a scalable, cost-effective backend architecture and efficient business. Online social media network has become part of human life by transforming the way users create new social relations or relate with family and friends. A social network, as the name suggests is a network of individuals created for social communication. It is a massive platform where people interact with others anywhere in the world online based on some relationship. The relationship can be friendship, family membership or others with some shared interests. Despite these considerable benefits, there are serious concerns and challenges about this new technology. The most important issue is related to security and privacy subjects in cloud-based environments. Accordingly, challenges and concerns related to cloud based environments have been identified and most appropriate current solutions for each challenge have been described. In overall, it is anticipated that cloud computing will be the most important and challenging issue in IT industry. As regarding the importance of this technology, we hope this paper will contribute to a better understanding of the vision of cloud computing and the challenges ahead for further researches. Likewise, social networks have seen enormous growth, with millions of Internet users actively participating across various social networking websites.","PeriodicalId":173948,"journal":{"name":"Internet of Things and Cloud Computing","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121382842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Design of a Portable Weighing Voice Quotation System Based on Single Chip Microcomputer","authors":"Liu Jing, T. Yan, Li Hui","doi":"10.11648/j.iotcc.20210902.11","DOIUrl":"https://doi.org/10.11648/j.iotcc.20210902.11","url":null,"abstract":": At present, most of the weighing systems also adopted the traditional mechanical weighing method, which did not have the function of voice broadcasting, low level of intelligence and poor interaction ability. Aiming at the difficulty of operation and poor interaction ability of traditional mechanical weighing system, a portable weighing voice quotation system based on single-chip microcomputer was proposed in this paper. AT89C51 single-chip microcomputer was used as the control core in the system, and HX711 weighing module and APR9600 voice control module were combined to realize real-time weighing, online display, unit price and quantity input, and voice quotation functions. The HX711 weighing module was adopt to realize real-time collection of weighing data, which was sent to AT89C51 single-chip microcomputer for processing after internal A/D conversion. A liquid crystal display was used to display the weighted data and the unit price, quantity and total price, and at the same time the APR9600 voice control module was driven for real-time voice broadcast. We had conducted a comprehensive test of the system. Experimental results showed that the system could realize the following functions, such as unit price input, weighing measurement, calculation, display, and voice broadcast functions. The system ran stably, cost-effectively, and could achieve the expected goals.","PeriodicalId":173948,"journal":{"name":"Internet of Things and Cloud Computing","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130388882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Multi-objective Offloading Decision Based on Combination Weighting Method for Multi-access Edge Computing","authors":"Dan Ye, Xiaogang Wang, Jin Hou","doi":"10.11648/j.iotcc.20210903.11","DOIUrl":"https://doi.org/10.11648/j.iotcc.20210903.11","url":null,"abstract":": Generally, in the edge computing scenario, edge devices can offload tasks to the edge servers to reduce device energy consumption and task execution delay. It is necessary to find an offloading strategy which can balance and minimize the task execution delay and device energy consumption. This is usually classified as a multi-objective problem. It is a common method to get the Pareto optimal solution set by using multi-objective optimization algorithm. However, there is a problem about how to find out the eclectic optimal solution that can embody the user's subjective consciousness and meet the objective information of Pareto optimal solution set. This paper solved this problem by combining subjective and objective combination weighting method. First, the subjective weight matrix which reflects the user's subjective consciousness is obtained by analytic hierarchy process. Then, the objective weight matrix which can embody the objective information of the index is obtained through the entropy method. Finally, the combination weight matrix is obtained by subjective and objective weighting method. After comprehensively evaluating the Pareto optimal solution set, the solution with the minimum comprehensive evaluation value is regarded as the Pareto compromise optimal solution. In this paper, the combination weighting method is applied to multi-access edge computing scenario and verify its feasibility in this scenario.","PeriodicalId":173948,"journal":{"name":"Internet of Things and Cloud Computing","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129214684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
