  4. 8. Exploiting Energy Awareness in Mobile Communication

    Författare :Ekhiotz Jon Vergara Alonso; Simin Nadjm-Tehrani; Daniele Puccinelli; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless transmission energy; energy consumption; mobile devices; power measurements; application energy; data pattern; trace-based simulation;

    Sammanfattning : Although evolving mobile technologies bring millions of users closer to the vision of information anywhere-anytime, device battery depletions hamper the quality of experience to a great extent. The massive explosion of mobile applications with the ensuing data exchange over the cellular infrastructure is not only a blessing to the mobile user, but also has a price in terms of rapid discharge of the device battery.

    Sammanfattning : The explosive growth of data in information society poses significant challenges in the timely delivery of information in the context of communication networks. Hence, optimal utilization of scarce network resources is crucial. LÄS MER

  7. 10. Analysis and Optimisation of Distributed Embedded Systems with Heterogeneous Scheduling Policies

    Författare :Traian Pop; Petru Ion Eles; Zebo Peng; Luis Almeida; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distributed embedded systems; Real-time analysis; Scheduling; Design optimisation; FlexRay; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : The growing amount and diversity of functions to be implemented by the current and future embedded applications (like, for example, in automotive electronics) have shown that, in many cases, time-triggered and event-triggered functions have to coexist on the computing nodes and to interact over the communication infrastructure. When time-triggered and event-triggered activities have to share the same processing node, a natural way for the execution support can be provided through a hierarchical scheduler. LÄS MER
