【摘要】：在多维异质网络中,由于承载不同的协议和网络,导致信道拥挤和分配不均衡。传统的多维异质网络信道分配算法采用基于信道切换的动态分配算法,在动态切换过程中易导致数据丢失和信道失衡。提出一种基于数据交叉项补偿机制的多维异质网络信道分配算法,进行多维异质网络信道协议分析与模型分析和求解,考虑用户间接收SINR的公平性,构建信道性能因子,引入一个局部性交叉项补偿信道切换中的失衡性实现算法改进。实验结果表明,改进算法使异质网络生命周期得到扩展,有利于数据的准确传输,避免在信道分配动态切换过程中导致的数据丢失和信道失衡,提高了分配效率和准确性,有效地保证了各用户接收SINR的公平性,信道分配性能上优越于传统算法,展示了较好的应用价值。
[Abstract]:In multi-dimensional heterogeneous networks, due to different protocols and networks, channel congestion and uneven allocation. The traditional multi-dimensional heterogeneous network channel allocation algorithm adopts the dynamic allocation algorithm based on channel switching, which can easily lead to data loss and channel imbalance in the process of dynamic handover. A multi-dimensional heterogeneous network channel assignment algorithm based on data crossover compensation mechanism is proposed. The channel protocol analysis, model analysis and solution of multi-dimensional heterogeneous network are carried out. Considering the fairness of receiving SINR between users, the channel performance factor is constructed. In this paper, a local crossover compensation algorithm is introduced to improve the unbalance of channel handoff. The experimental results show that the improved algorithm can extend the lifetime of heterogeneous networks, facilitate the accurate transmission of data, avoid data loss and channel imbalance caused by dynamic handoff of channel allocation, and improve the efficiency and accuracy of allocation. The fairness of receiving SINR is effectively guaranteed, and the channel allocation performance is superior to the traditional algorithm, which shows the better application value.
