Collaborative cloud-edge computing networks (CCECNs) is an effective way to alleviate the limitation of computing capacity by offloading complex tasks from IoT. Thus, this paper mainly proposes selective offloading network resource optimization approaches to address the offloading network resource problems for user requests in CCECNs. Simulation results show that proposed approaches can optimize network resource allocation and can reduce end-to-end (E2E) latency and blocking probability.","PeriodicalId":6756,"journal":{"name":"2021 19th International Conference on Optical Communications and Networks (ICOCN)","volume":"24 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87776185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With different absorption layer thickness, we simulate the gradient distribution of the band gap of the CIGS thin-film absorption layer in the solar cell. By calculating the device efficiency with the minimum band gap at different positions, we have found the most suitable position of the minimum band gap for this model is near the front absorption layer and the device efficiency with absorption layer thickness 1.5um is similar to that of 2um, which means the thin absorption layer of the solution method can be effective.","PeriodicalId":6756,"journal":{"name":"2021 19th International Conference on Optical Communications and Networks (ICOCN)","volume":"51 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72788448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The NBR is consist of a taper waveguide, π phase shifted antisymmetric Bragg grating (π-PS-ASBG) and uniform Bragg grating. Two sections are integrated on an identical InP wafer and share one continuous waveguide. Because of the hybrid mode resonance in the passive section, it has a relatively long effective length to narrow the linewidth of laser.
