随着用户对无线通信要求的提高,协作通信将成为未来的发展趋势。本文研究了一种基于偏好连接和随机连接的复杂网络模型来求解实际网络--CCN(协作通信网络)。首先,CCN的演变是由四个不同的概率步骤。同时,给出了节点度的速率方程,分析了CCN的演化过程。其次,通过计算速率方程和数值模拟分析了度分布。最后,通过数值仿真研究了CCN在随机攻击和蓄意攻击下的鲁棒性,分析了度分布、平均路径长度和平均度对CCN鲁棒性的影响。本文的研究成果对构建CCN进行通信资源规划具有重要意义。
With the requirements of users enhanced for wireless communication, the cooperative communication will become a development in tendency future. In this paper, a model based on complex networks with both preferential and random attachments is researched to solve an actual network-CCN (cooperative communication network). Firstly, the evolution of CCN is given by four steps with different probabilities. At the same time, the rate equations of nodes degree are presented to analyze the evolution of CCN. Secondly, the degree distribution is analyzed by calculating the rate equation and numerical simulation. Finally, the robustness of CCN is studied by numerical simulation with random attack and intentional attack to analyze the effects of degree distribution, average path length and average degree. The results of paper are more significant for building CCN to program the resource of communication.
