• To deal with the high computational complexity of solving MINLP, we linearize it as a mixed-integer linear programming (MILP) problem, which can be solved using commercial solver. Through extensive numerical studies, we show the high efficiency of our proposed joint-optimization based algorithm.
The rest of the paper is organized as follows. Section II summariestherelatedwork.SectionIIIintroducesoursystem model. The cost optimization is formulated as an MINLP problem in Section IV and then it is linearized in Section V. The theoretical findings are verified by experiments in Section VI. Finally, Section VII concludes our work.
