网络数据多信道传输路径规划方法研究

Multi Channel Network Data Transmission Path Planning Method Research

对网络数据多信道传输路径进行合理规划,可以保障网络数据传输效率和质量。进行传输路径规划时,需要计算网络数据传输总体能耗和传输节点平均负载,对其进行寻优,而传统算法利用网络传输与网络延迟间的率失真函数关系,组件网络数据多信道传输模型,忽略了传输总体能耗和传输节点平均负载,降低了路径规划的合理性。提出一种联合多路由算法的网络数据多信道传输路径规划方法。首先先组建网络通信链路干扰图,计算出各个信道的干扰水平,依据计算的结果得到每条路由路径的信道干扰程度,计算出信道分配的权重阈值,获取干扰较小的信道集合,采用Vornon的思想计算出网络数据传输总体能耗和传输节点平均负载,采用启发式策略进行路径规划寻优,有效的完成了网络数据多信道传输路径规划。仿真结果表明,所提方法能够显著提高网络数据传输质量和效率,具有较强的实用性。

In this paper,we proposed a planning method for multi-channel transmission path combined with multi routing algorithm. Firstly,we built the interference graph of network communication link and calculated the interference level of each channel. The channel interference degree of each routing path was obtained according to the calculation result. Then we calculated the weight threshold of channel allocation to obtain the channel set with less interference. We also used the Vornon thought to calculate overall energy consumption and mean load. Finally,we used heuristic strategy to optimize path planning and completed multi channel transmission path planning effectively.The simulation results show that the method mentioned above can improve the transmission quality and efficiency apparently. It has better practicability.
