Abstract
Context-awareness enables systems to be tailored to the needs of users and their real circumstances at certain times. A noteworthy trend in software development is that an increasing number of software systems are being developed by individuals with expert knowledge in other sectors. Because of the most current context-aware development toolkits are intended for software developers, these types of systems cannot be easily developed by non-technical consumers.The development of tools for designing context-aware frameworks by consumers who are not programming experts but are specialists in the area of implementation would result in the faster adoption of such services by businesses. This thesis provides a cloud-based framework for people without programming experience to create context-aware mobile applications. The platform can provide a lightweight distribution of packaged applications that allows experts to send specified information to mobile users based on their context data without overlapping the rules of the application.An energy-efficient mobile application was developed to acquire contextual information from the user device and to create quality data accordingly. The framework adopts Platform as a Service (PaaS) and containerization to facilitate the development of context-aware mobile applications by experts in various domains, rather than developing a tool for each domain in isolation while considering multitenancy.The salient features of the framework have been empirically tested among ten non-technical people who are experts in the tourism domain.The result was 90% according to the System Usability Scale, which proves that this framework is effective and suitable for this domain
