Efficient Configurations for Dynamic Applications in Next Generation Mobile Systems
Abstract
Next generation wireless systems support a wide range of communication protocols and services, opening new design challenges. The desired flexibility presupposes effective approaches that exploit the system configurations with an optimal way. A well-known state-of-the-art example of a wireless platform is the Software Defined Radio (SDR). SDRs are characterized by strict performance requirements that introduce a lot of dynamism in respect with the resource utilization. Additionally, these devices experience transient overloads due to workload bursts or hardware malfunctions. The aforementioned reasons lead the system to take timely reactions to unexpected usage scenarios. The current chapter concentrates on these design challenges exploiting the system scenario methodology, proposing solutions especially for wireless communication systems. More precisely, it will be studied the tradeoffs between the representativeness of the scenarios (clustering overhead), the implementation of the scenario detection (detection overhead) and the platform tuning cost (switching overhead).
