This\u0000problem can be solved by different algorithms such as Genetic Algorithm (GA), Artificial Bee Colony (ABC), Ant Colony Optimization\u0000(ACO), etc. Shuffled Frog Leaping Algorithm (SFLA) is implemented in the proposed work, to solve the RWA problem in long-haul\u0000optical networks. The goal is to use minimum number of wavelengths and to reduce the number of connection request rejections.\u0000Cost, number of wavelengths, hop count and blocking probability are the performance metrics considered in the analysis. Various\u0000wavelength assignment methods such as first fit, random, round robin, wavelength ordering and Four Wave Mixing (FWM) priority\u0000based wavelength assignment are used in the analysis using SFLA. Number of wavelengths, hop count, cost and setup time are\u0000included in the fitness function. The SFLA algorithm proposed, has been analyzed for different network loads and compared with the\u0000performance of genetic algorithm.","PeriodicalId":56293,"journal":{"name":"Informacije Midem-Journal of Microelectronics Electronic Components and Materials","volume":"144 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2019-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77532507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
