Abstract:

To study spectrum allocation problem in Cognitive Wireless Mesh Network (CWMN), an immune-based multi-objective optimization algorithm was proposed. The problem was modeled as a multi-objective optimization problem to maximize total bandwidth and minimize the total number of occupied spectra. Antibody encoding, whole cloning operator and non-dominated anti-body selection operator that are suitable for solving the problem were designed. The simulations results show that the proposed algorithm can obtain the Pareto optimal solutions of CWMN spectrum allocation, which improves the total bandwidth and minimizes the occupied spectra, so it optimizes the spectrum allocation performance.

摘要:

针对认知无线Mesh网络(CWMN)的频谱分配问题,提出了一种基于免疫多目标优化的实现算法。该算法将要求解的频谱分配建模为最大化总带宽和最小化占用频谱数的多目标优化问题,设计了适合问题求解的抗体编码方式、整体克隆算子和非支配抗体选择算子。仿真实验结果表明,所提算法可以求得CWMN频谱分配问题的Pareto最优解,提高了最大化总带宽,减少了最小化占用频谱,优化了频谱分配性能。
