Abstract: Based on restriction and characteristic of channel assignment,an immune strategy algorithm(ISA) is presented to solve the dynamic channel assignment problem in cellular telecommunication systems.The algorithm can assure greatest compact assignment.And focused on the degradation of genetic algorithm,immunization strategy algorithm is introduced for channel assignment,which can resolve degradation preferably.The experiment results demonstrate that the callblocking probability of the immune strategy algorithm for channel assignment(ISACA) is lower than all of the fixed channel assignment(FCA),dynamic channel assignment(DCA) and improved genetic algorithm dynamic channel assignment(IGADCA).
Key words: channel assignment, cellular network, immune strategy algorithm(ISA)
摘要: 根据信道分配的限制条件和特点应用免疫策略算法(ISA),提出了基于 ISA的一种整体优化的动态信道资源分配方案,其特点是保证最大程度的紧致分配。同时针对遗传算法的退化现象引入免疫策略算法,较好解决了遗传算法的退化问题。实验仿真表明,该方案与现有的固定信道分配(FCA)、动态信道分配(DCA)方案和改进遗传算法信道分配方案(IGADCA)相比,有较小的呼阻率。
