This extended abstract outlines a novel optimization approach for multi-band linear collaborative spectrum (LCS) sensing based on harmony search heuristics. Besides, the description of a centralized system architecture is also included in this manuscript, which is capable of processing the captured spectrum measurements from several nodes in a LCS fashion and storing the decisions made on the spectrum...
There is an increasing demand for computing systems composed by heterogeneous computers, connected by different types of networks, and that allow for accessing a wide range of services in a seamless way. Some of those computers are mobile or embedded and have limited resources, and can be overloaded when trying to handle their users demands. Then it is not possible to ensure a proper behaviour of...
Applications of high-quality multimedia embedded systems (HQMES) contain concurrent functionality pieces; they may have a flexible structure consisting of services, components, or tasks. This allows applications to offer different execution possibilities to provide a same (or different) output quality. Since multimedia applications are typically greedy resource consumers, they may interfere one another's...
Media processing in high-quality multimedia embedded systems (HQMES) has real-time constraints. Timely processing and rendering of video frames and audio samples is essential to meet user expectations. The nature of incoming media suffers unforeseen variations which have different resource requirements. Therefore, HQMES have to integrate policies for efficiently and smoothly adapting to these changes...
