摘要 在分层异构移动云中,为了有效管理移动节点的功率消耗,同时考虑到短距离通信中的移动节点可以传输数据流给附近的节点,并减少移动节点将接收到的数据分配给其他移动节点所消耗大量功率的问题。基于已提出的分层异构移动云架构,联合考虑数据速率,分析研究了动态移动云协作传输算法。分层异构移动云中的协作传输算法有效地融合了蜂窝与短距离通信,可根据协作组中每个用户转发能力来控制蜂窝网络传输给每个移动节点数据流。通过对动态移动云中协作传输与非协作传输的能量消耗的比较分析,获得了动态移动云协作传输算法,节省了更多的能量,同时减小了数据传输的时延。研究结果表明,基于分层异构移动云架构的协作传输能改善数据传输的能量消耗。 On the network architecture of layered heterogeneous mobile clouds, in order to effectively manage the mobile node power consumption and consider the short-range communication mobile node can transmit data stream to the near node and then reduce the mobile node to distribute the data of received data to other mobile nodes consume large amounts of pow- er. Based on the network architecture of layered heterogeneous mobile clouds and considering the data rate, the dynamic mobile cloud collaboration transmission algorithm is analyzed. The research methods of cooperative transmission algorithm in the layered heterogeneous mobile clouds blend of cellular and short-range communication effectively and according to each user of forwarding capacity control cellular network transmission to the data stream of each mobile node. Through the energy consumption of non-cooperative transmission and cooperative transmission is also analyzed and compared, the dy- namic mobile cloud collaboration transmission algorithm can save much energy and reduce the delay of data transmission. The results show that the energy consumption of data transmission can be improved with the cooperative transmission based on the network architecture of layered heterogeneous mobile clouds.
