This paper presents GEmSysC, an unified cryptographic API for embedded systems. Software layers implementing this API can be built over existing libraries, allowing embedded software to access cryptographic functions in a consistent way that does not depend on the underlying library. The API complies to good practices for API design and good practices for embedded software development and took its...
The unpredictability of virtual machines workload makes effective CPU resources allocation a hard assignment for the hypervisor. Even if a virtual machine is allocated with adequate CPU resources, the quality of service of those running both CPU and I/O intensive tasks (heterogeneous workload), may be seriously affected if they are not provided in a timely manner. As server consolidation grows, CPU...
We call "Violent" (from portuguese: velocity and direction), a context-aware routing protocol that aims at obtaining and processing environment data such as velocity and direction of nodes as they establish contacts with each other in delay-tolerant networks (DTNs). This context information is used by the proposed algorithm - along with the node's position and time of the last encounter...
The scheduler's main goal in a general purpose multitasking operating system is to provide a fair share of processor time to all processes, in order to achieve good performance and an adequate response time for interactive applications. Each process has its own demands for processing and response time, which can not always easily be informed by the user or inferred by the scheduler itself. This article...
