21. Improving the Efficiency of Control Signaling in Wireless Multiple Access Systems
Sammanfattning : Prior to the transmission of payload data in any multiple access system, there is generally a need to send control information such as scheduling assignments, transmission parameters and HARQ acknowledgments. This process is called control signaling and has a significant impact on the overall system performance. LÄS MER
22. Resource Allocation for Mobile Edge Computing Systems
Sammanfattning : The rapid development of mobile information industry has led to the emergence of various mobile applications in areas such as industrial automation, health care or transportation. These applications often require heavy computations with strict latency requirement, which may surpass the processing abilities of the mobile devices. LÄS MER
23. Mobility management in heterogeneous access networks
Sammanfattning : This thesis proposes, describes and validates solutions to enhance mobility in heterogeneous access networks. Wireless access networks have become available almost everywhere and current research strives to make them pervasive. LÄS MER
24. Figure-ground segmentation using multiple cues
Sammanfattning : The theme of this thesis isfigure-ground segmentation.We address the problem in thecontext of a visual observer, e.g. a mobile robot, movingaround in the world and capable of shifting its gaze to andfixating on objects in its environment. LÄS MER
25. Access selection in multi-system architectures : cooperative and competitive contexts
Sammanfattning : Future wireless networks will be composed of multiple radio access technologies (RATs). To benefit from these, users must utilize the appropriate RAT, and access points (APs). In this thesis we evaluate the efficiency of selection criteria that, in addition to path-loss and system bandwidth, also consider load. LÄS MER
