They are protected from interference by establishing national radio quiet zones (NRQZs). However, NRQZs do not prevent interference from satellite networks with intersatellite links. This causes impairment in directly observing cosmic sources. Therefore, current knowledge of the universe is inaccurate being obtained from filtered signals. However, accurate knowledge can be obtained in RASs via a pristine observation of Srcs using cognitive radio (CR) technology. This paper, examines the suitability of CR spectrum sharing models for interference protection of RASs. It proposes an interference protection framework and investigates the satellite's transmit opportunities using visibility duration data of RASs. It then examines the end to end delay of the satellite network when the framework is used. Simulation is conducted for a constellation of low earth orbit satellites and the obtained results show that transmit opportunities exist for intersatellite links when the interweave spectrum sharing model is used without causing any interference to RASs or significantly increasing the end to end delay.","PeriodicalId":310313,"journal":{"name":"2015 European Conference on Networks and Communications (EuCNC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115344840","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}

Different technologies such as Network Functions Virtualization (NFV) and Software Defined Networking (SDN) are being considered to address the future needs of 5G networks. However, future applications such as Internet of Things (IoT), video services and others still unveiled will have different requirements, which emphasize the need for the dynamic scalability of the network functionality. The means for efficient network resource operability seems to be even more important than the future network element costs. This paper provides the analysis of different technologies such as SDN and NFV that offer different architectural options to address the needs of 5G networks. The options under consideration in this paper may differ mainly in the extent of what SDN principles are applied to mobile specific functions or to transport network functions only.","PeriodicalId":310313,"journal":{"name":"2015 European Conference on Networks and Communications (EuCNC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114323128","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 proposed FCF-M is composed of controller failure detection and switch reassignment. In the controller failure detection, each controller checks the timestamp of its preceding controller. If a controller is failed, its succeeding controller will check its preceding controller. Because a failed controller does not prevent its preceding controller from healthy check, the proposed FCF-M can prevent a single point of failure (SPOF) for healthy check. We also make use of an adaptive timeout delay to reduce failure detection time. In the switch reassignment, when a controller is failed, we need to reassign the switches under the failed controller to an alternative controller. We consider controller load and distance between a switch and a controller to choose an alternative controller for reducing delay. The proposed FCF-M can achieve intra-domain controller failover and inter-domain controller failover. Using EstiNet, simulation results show that the proposed FCF-M outperforms the Devolved controller (DC) in terms of average end-to-end delay and failover time.","PeriodicalId":310313,"journal":{"name":"2015 European Conference on Networks and Communications (EuCNC)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123228342","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}
