论文摘要
认知无线网络（CRN）是下一代无线通信。这种类型的网络需要有效的频谱分配方法。本文介绍了一种新的元式进化方法，用于在临时网络环境中解决通道分配问题。建议的方法基于图理论模型，并在聚类的临时网络拓扑中寻求解决频谱分配问题的解决方案。该方法称为帝国主义竞争算法（ICA），提供了一种将可用通道分配给群集头的方案，以最大化频谱效率，并最大程度地减少CO-CONIMS CO-CHANNENEL ICTERCORTER。建议的方法测试了几种情况。将基于ICA的方案的性能与基于遗传算法的方案进行了比较。
Cognitive radio networks (CRNs) is the next generation of wireless communication. This type of network requires efficent spectrum allocation methods. This paper presents a new meta-heuristic evolutionary method for solving the channel allocation problem in an ad hoc network context. The suggested method is based on a graph-theoretic model and seeks a solution for the spectrum allocation problem in a clustered ad hoc network topology.The method is referred to as imperialist competitive algorithm (ICA)and provides a scheme for allocating the available channels to cluster heads maximizing spectrum efficiency and minimizes co-channel interference. The suggested methods are tested for several scenarios; the performance of the ICA-based scheme is compared with the genetic algorithm based scheme.
