【摘要】：双层宏蜂窝/小蜂窝异构网络不但能解决室内用户的覆盖问题,还可以大幅度降低网络能量消耗。但是,网络中的跨层和层间干扰会降低网络性能,高能效的无线资源分配和优化方法无疑将成为解决此问题的有效途径。首先,给出了一个移动云计算管理框架。然后,针对无线单链路定义了空间传输效率,比较和分析了多种单链路效率度量的含义和数学性质,并针对基于LTE-A(long term evolution-advanced)的移动云计算接入网络,提出了一种高能效的无线资源管理算法。为了快速地达到最优解,设计了一个快速收敛的迭代算法。仿真分析说明此资源管理算法实现了移动云计算系统能量效率和吞吐量的高效折中。
[Abstract]:The double-layer macrocellular / small cellular heterogeneous network can not only solve the coverage problem of indoor users, but also greatly reduce the energy consumption of the network. However, cross-layer and inter-layer interference in the network will degrade the performance of the network, and energy-efficient wireless resource allocation and optimization will undoubtedly become an effective way to solve this problem. First, a mobile cloud computing management framework is presented. Then, we define the spatial transmission efficiency for wireless single-link, compare and analyze the meanings and mathematical properties of various single-link efficiency metrics, and aim at the mobile cloud computing access network based on LTE-A (long term evolution-advanced). An energy efficient wireless resource management algorithm is proposed. In order to achieve the optimal solution quickly, an iterative algorithm with fast convergence is designed. The simulation analysis shows that the resource management algorithm achieves the efficient compromise between energy efficiency and throughput of mobile cloud computing system.
