Abstract

Many application level qualities are functions of avail-ablecomputation resources.Recent studies have handledthe computation resource allocation problem to maximizethe overall application quality.However, such QoS problemis fundamentally a multi-dimensional optimization problemthat requires extensive computation.Therefore, online usageof optimization procedures may significantly reduce thecomputation resource available for applications.This raises thequestion of how to best use the optimization procedures fordynamic real-time task sets.This paper proposes a methodcalled service classes configuration to address the QoSproblemwith dynamic arrival and departure of tasks.A simplifiedradar application is used as an illustrative example.
