Radio Resource Adaptive Adjustment in Future Wireless Systems Based on Application Demands

In wireless communication systems the resource anagement needs to integrate adaptive techniques to the varying network conditions, due to the eventual dramatic changes that may occur in the link quality. Therefore, it may be desirable to support adaptable resource management techniques that are able to find their decisions in the network configuration information or in the source application description. Accordingly, the paper identifies, explores and proposes adaptive techniques for resource management so as to enhance the transmission quality on wireless systems either through a feedback channel or by making use of the network virtualization concept. Setting up dependencies between the application requests and the radio channel conditions, a feedback loop adaptively configures modulation and coding schemes, calibrates multi-antenna system, controls power per beam allocation or invokes a linear precoding. Finally, when the application requests exceed the network capacity, by the network virtualization process the adaptive potential of the application parameters can be employed, either through source fragmentation or source code adaptation.
