Compensated cross layer resource allocation algorithm in wireless multi hop network

为消除过时频道状况信息(channel state information,CSI)对分布式无线多跳网络条件下跨层资源分配速率的负面影响,设计补偿式跨层联合资源的分配方案。采取瞬时频道状况信息以及过时频道状况信息互相存在的条件几率密度方程,推导信噪比(SINR)特定基础上容量的闭式解;为有效弥补局部来自网络性能方面的空缺,设计兼顾过时频道状况信息的联合拥塞控制、信道支配系统以及功率把控的计算方案。实验数据的比较和分析结果表明,在繁杂程度较低的基础上,该推导方案增强了分布式多跳网络资源在支配过程中的科学和有效性,增强了对应的网络宏观效用性。

To eliminate the negative impact of the outdated CSI（channel state information channel state information）on cross layer resource allocation rate in distributed multi hop wireless network,the compensated cross layer joint resource allocation calculation measure was designed.The instantaneous channel condition information and conditional probability density equation were adopted.The closed form solution of the signal to noise ratio（SINR）was derived.To make up for the vacancy of the local network performance,the combined congestion control,channel control system and the power control system were designed.The results of comparison and analysis of experimental data show,on the premise of relatively low complexity,this derivation scheme directly enhances the scientificalness and effectiveness of the distributed multi hop network resources in the control process,and the macro effectiveness of corresponding network is enhanced.
