超图在密集无线网络优化中的应用

         

摘要

未来网络中,无线终端设备和无线业务量都将呈井喷式增长,而网络将呈现高密集化趋势,导致设备间的直接和累积干扰复杂.为了简化复杂的干扰模型且克服传统二元图在刻画累积干扰方面的不足,介绍了超图模型对干扰模型的刻画方法,并对超图模型的提升进行了进一步分析和研究,最终基于超图模型提出了对资源进行复用的集中分布式的博弈方法,并利用仿真实验证明了方法在性能上带来的提升.%In the future network, the amount of wireless terminal equipment and wireless traffic would be in blowout growth, while the network exhibit he high-density trend, resulting in direct and cumulative complex interference. In order to simplify the complex interference model and overcome the shortcomings of the traditional binary graph in characterizing the cumulative interference, the description of interference model by hyper-graph model is presented, and the different hyper-graph models also analyzed and discussed. And finally based on hyper-graph model, the centralized distributed game method for the reuse of resources is proposed. And the simulation indicates that this method is clearly improved in performance.
