文摘Multicast device-to-device(D2D)communication technology is considered as one of the new technologies in the fifth generation(5G)networks that directly addresses the need for content sharing among internet users.In fact,when direct communication is available between devices,the spectral efficiency is improved by reusing the licensed cellular spectrum.The current studies show that D2D communication increases network capacity and reduces latency.In order to achieve the alternate capabilities,coordination is required to implement interference management.We considered subcarrier allocation for the uplink,in addition to the power control that takes place on the underlay network.The completed data rate in single multicast communication is significantly reduced and limited by nodes with lower channel quality.In this paper,we used Shuffled Frog Leaping Algorithm(SFLA)for resource allocation(RA)in D2D multicast communications.We compared the results of the SFLA algorithm with the Firefly Algorithm(FA),Ant Colony Optimization(ACO)and Particle Swarm Optimization(PSO);in terms of D2D user throughput,Cellular User(CU)throughput,network average throughput,network interference and signal interference noise ratio(SINR)target.The simulation results show that SFLA clearly outperforms other algorithms in terms of data rate under the high pressure of infeasibility.
文摘针对化工生产过程的安全性问题,提出基于混合蛙跳(shuffled frog leaping algorithm,SFLA)的FCM聚类算法。该算法引入寻优能力强的SFLA求得最优解作为FCM算法的初始聚类中心,然后利用FCM算法优化初始聚类中心,最后求得全局最优解,从而有效避免了F C M算法易陷入局部最优和对初始值敏感的缺点。将该算法用于化工生产状态数据的聚类分析,实验结果表明,本文算法与F C M聚类算法相比,提高了算法的寻优能力,聚类效果更好;并且能够快速、客观地对化工生产过程的状态进行判别,为其安全运行提供了保障。
