无线Ad Hoc网络中一种集中式信道分配方法

A Centralized Channel Allocation Method in Clustered Ad Hoc Networks

Mahboobeh Parsapoor, Urban Bilstrup

摘要:

认知无线电网络是下一代无线通信的发展方向。这种类型的网络需要有效的频谱分配方法。本文提出了一种新的元启发式进化方法,用于解决Ad Hoc网络环境中的信道分配问题。该方法基于图论模型,以最大化频谱利用率和最小化同频干扰为目标,提出了一种帝国主义竞争算法(ICA),用于解决分簇自组织网络拓扑中的频谱分配问题.建议的方法进行了测试的几种情况下,ICA为基础的计划的性能进行了比较,遗传算法为基础的计划。

英文摘要:

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.
