| 摘 要： | 该文针对多信道无线mesh网络，采用基于效用最优的定价机制，提出了一种功率-干扰价格模型，并基于该模型提出了一种分布式联合信道分配和功率分配算法。每个节点根据自己所消耗功率状况合理地定功率价格，并根据自己所受干扰状况合理地定干扰价格。通过功率价格和干扰价格来调节链路的信道分配和功率分配，使网络效用最大化。仿真结果表明：所提出的算法能够快速、平稳地收敛到近似最优解。同时还仿真了网络可用信道数目、节点射频数目和功率对系统性能的影响，可以为网络配置提供参考。

| Abstract: | A power-interference pricing model is presented using pricing scheme based on utility optimization.Then,a distributed jointly channel assignment and power allocation algorithm is proposed for multi-channel wireless mesh networks.Each node adjusts its power price according to the amount of power expended,and adjusts its interference price according to the interference suffered.To maximize the network utility,the channel assignment and power allocation are adjusted through power prices and interference prices... |
