Joint cloud computing and wireless networks operations: A game theoretic approach

In mobile cloud computing systems, cloud computing can have significant impacts on wireless networks. Cloud computing and wireless networks have traditionally been addressed separately in the literature. In this paper, we propose to jointly study dynamic cloud and wireless networks operations so as to improve end-to-end performance in the mobile cloud computing environment. Unlike most existing studies on wireless networks, where only the spectrum efficiency is considered, we consider not only the spectrum efficiency in wireless networks but also the pricing information in the cloud, based on which power allocation and interference management in wireless networks are performed. We formulate the problems of cloud media service price decision, resource allocation and the interference management in the mobile cloud computing environment as a three-level Stackelberg game. A backward induction method is used to analyze the proposed Stackelberg game. Simulation results are presented to show the effectiveness of the proposed scheme.
