Fault-tolerant design method for tizen applications considering core- and API-level faults

Abstract

Performance and reliability of individual components in a component-based software system is very important. Specially, if different components are inherently faulty or under rapid development, adopting a fault-tolerant design approach is recommended. According to our analysis presented in this paper, the emerging Tizen platform is also under development and many of its components have potential defects. Application developers have little or even no control over these defects. Consequently, Tizen application developers should adopt fault-tolerant design methods so that component level faults do not hamper overall performance of their developed applications. To the best of our knowledge, no such studies are present for this platform. In this paper, we presented a new fault-tolerant design method for Tizen applications considering both core- and API-level faults along with their impacts on user experiences. To do so, first, we use static and dynamic analyses techniques to identify existing faults and their impacts in Tizen platform. Based on the accumulated results and major issues identified through analyses, we propose a fault-tolerant design method to minimize effects of the discovered faults. We implement our method for several customized applications to evaluate its performance. Experimental results demonstrate that our proposed method enhances fault tolerance of Tizen applications compared to that of its conventionally designed counterpart.
