Optimal Resource Control of Multi-Processor Multi-\ud Radio Nodes using semi-Markov Decision Processes

摘要

An optimal resource control mechanism for a multiprocessor,\udmulti-radio node architecture is proposed. To achieve\udour objective, a constrained semi-Markov decision problem is\udformulated, which not only provides optimal resource control but\udalso meets quality of service demands imposed by application. For\udeach sensed event, the desired energy efficiency and performance\udtradeoff is achieved by the optimal stochastic policy, which\udselects an appropriate set of processors and radios. The proposed\udsolution is assessed using the reported energy consumption\udmeasurements for the existing platforms. Performance evaluation\udresults point towards the importance of proper pairing of processor\udand radio in achieving the energy efficiency and performance\udtradeoff. The proposed solution can also be employed for hand\udheld devices equipped with multiple processors and radios.
