在线开放通信网络信道分配算法优化

针对传统的通信网络信道分配方法进行信道分配时存在信道分配不准确及效率低的问题,提出一种基于干扰度与链路优先级划分的通信网络信道分配方法.由Posisson分布模型建立通信网络节点流量模型,对链路流量及干扰进行评估,建立干扰模型计算出对应干扰程度等级,结合流量模型及干扰模型对分配的信道设计权重值,根据计算出的权值作为选取信道的依据,并根据优先级对网络信道进行分配.实验结果表明,相比传统的信道分配算法,采用改进算法进行信道分配吞吐量较高,信道分配精确度好,具有一定的优势.

Optimization for online open communication network channel allocation algorithm

In order to solve the problem that the inaccuracy channel allocation and low efficiency problem exist when the traditional communication network channel allocation method is used for channel allocation, a communication network channel allocation method based on the interference degree and link priority was proposed. The communication network node flow model was established with the Posisson distribution model to assess the link traffic and interference. In addition, the interference model was established, and the corresponding disturbance degree level was calculated. In combination with both flow model and interference model, the weight for the allocated channel was designed. The calculated weight was taken as the basis of selected channel, and the network channel was allocated according to the priority. The results show that compared with the traditional channel allocation algorithm, the improved algorithm for channel allocation has higher throughput and better channel allocation accuracy, and has a certain advantage.
