摘要
为了提高蜂窝网络中频率资源的利用率,提出一种基于选择性变异技术的频率分配方法。该方法将网络中的电磁干扰作为系统的能量函数,通过动态改变算法迭代过程中所需要满足的约束条件来实现频率配置的快速优化。仿真结果表明,其搜索效率远高于模拟退火算法以及微正则退火算法。
In order to improve the frequency resource exploitation in cellular network,a frequency assignment approach based on selective mutation technique is proposed.The approach regards electric-magnetic interference in the network as an system energy function,and realizes the rapid optimization of frequency configuration through dynamically altering the restrictions required by the algorithmic iterative process.Simulation results indicate that the proposed algorithm is far more efficient at search than either the simulated annealing algorithm or the microcanonical annealing algorithm.
