    Sammanfattning : To assure the sustainable development of mobile networks, it is crucial to improve their energy efficiency. This thesis is devoted to the design of energy-efficient mobile networks. A cross-layer design approach is adopted. LÄS MER

  7. 5. Wireless Channel Prediction with Location Uncertainty

    Författare :Srikar Muppirisetty; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Spatial wireless channel prediction is important for future wireless networks, andin particular for anticipatory networks to perform proactive resource allocationat different layers of the protocol stack. In this thesis, we study location-awarechannel prediction with uncertainty in location information and understand its utilization to enhance the communication capabilities in wireless networks.
