有效利用协同空间复用的“绿色”资源分配策略

A green resource allocation strategy for utilizing cooperative spatial multiplexing

构建绿色环保的移动通信网络已成为构建和谐社会的一个组成部分.针对未来通信系统的节能问题,提出了一种有效利用协同空间复用的资源分配策略.该策略通过动态调整源节点的发送功率和协作水平来控制参与协同的节点数,从而能够很好地为不同业务提供QoS保证,并且最大限度地节约系统资源的消耗.通过仿真验证了该算法在中断概率和节约系统资源方面的良好性能.

Building green communication systems is a part of building the harmonious society. A novel resource allocation algorithm was proposed to reduce the energy consumption of future communication systems by utilizing cooperative spatial multiplexing. In this algorithm, the number of cooperative nodes was determined by source power control and level of cooperation （LOC） adjustment to minimize the energy consumption of the system under the QoS constrains. Simulation results show that the performance of the scheme is superior to those of existing algorithms.
