摘要：

This paper addresses the problem of energy efficiency for content distribution over wireless network by introducing the mobile cloud. The base station (BSs) distributes a common content to a number of adjacent mobile terminals (MTs) with mobile-to-mobile (M2M) cooperation. A clustering formation algorithm and two schemes for content distribution are proposed in this paper. All requesting MTs are grouped into several cooperative clusters. Their cluster heads constitute a mobile cloud, in which every member can exchange information by short-range links with low-power. Only a whole content is received by some selected cluster heads by cooperation through long range (LR) links and more contents are received by other cluster heads through short range (SR) links. Then every cluster head multicast the content to its cluster members. Analysis of mathematical models and simulation results demonstrates that the proposed schemes significantly reduce the total energy consumption of MTs, while achieving a lower transmission delay.
