Abstract: In the last two decades, the worst-case execution time (WCET) bound computation was a topic mainly related with hard real-time systems for aerospace and defense applications. Recently, however, it has become crucial in other domains dealing with timing guarantees. This includes among others, the automotive industry, where V2V and V2X applications for autonomous vehicles are demanding not only fault-tolerant responsiveness, but also the guarantee that timing deadlines will not be violated. In this sense, it is a mandatory condition to have an accurate determination of the WCET parameter in order to guarantee the hard-real time response of these critical systems to the environment. We propose in this paper a method to bound WCET for workloads running in the LEON3 and MIPS architectures. This approach performs a static timing analysis of the application code and based on the IPET technique, bounds the WCET. In addition to the use of the IPET technique, the proposed approach also takes adv

Abstract: The development of mobile devices and the spread of wireless network help share and exchange information and resources more easily. Therefore users are able to use the information and service more free than previous wire network due to development of wireless network and device. In order to provide appropriate user services, it enables to recognize user’s current state, analyze the user’s profile like user’s tendency and preference, and draw the service answering the user’s request. Most existing frameworks, however, are not very suitable for mobile devices because they were proposed on the web-based. And other context information except location information among user’s context information is not much considered. Therefore, this paper proposed the context-aware framework, which provides more suitable services by using user’s context and profile.
