One of the main tasks in this respect is Air Traffic Control (ATC). Until today, European airspace is fragmented and divided along national borders. In other words, limited resource airspace is divided into zones, where each zone is subdivided into sectors and managed by air traffic controllers. This fact in turn leads to inefficiency and congestion, resulting in a deterioration of flight safety, greater costs, more delays and higher emissions. To develop a more comprehensive understanding of airspace utilization, economic, emission-related effects and mechanisms for detecting and resolving air traffic conflicts, flight models are indispensable. This research simulates different realistic air traffic models with and without air traffic conflicts that can compromise flight safety and paralyze airspace. Regarding to the air traffic conflicts, weather events, emergency situations, human factors and cyber attacks against aircraft and ground infrastructure are investigated and considered. In the simulation process an user defined number of flights with a selection of pseudo-random weighted air traffic conflicts is generated to obtain reliable and structured data. These event-driven data are subsequently used for future ATM solutions such as digital human assistance systems or for fully automated Unmanned ATM (UTM) solutions to ensure safe and efficient operations while reducing costs, delays and emissions.","PeriodicalId":131597,"journal":{"name":"2022 International Conference on Broadband Communications for Next Generation Networks and Multimedia Applications (CoBCom)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122275576","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 main goal of these algorithms is to provide services that meet the QoS requirements of individual users while ensuring efficient use of network resources. Cloud Radio Access Network (C-RAN) is a future direction in wireless communications to implement cellular radio access subsystems in current 4G, 5G and next generation networks. In the C-RAN architecture, the baseband units (BBUs) reside in a group of virtual base stations connected to the radio remote controllers (RRHs) through a high-bandwidth, low-latency front-haul network. The C-RAN architecture offers significant advantages in terms of centralized resource pooling, network flexibility, and cost savings. In this work, we demonstrate a heterogeneous C-RAN network that implements a dynamic resource allocation algorithm that enables optimal resource utilization in mobile communication networks. The C-RAN network is implemented with OpenStack and uses Docker containers to switch between LTE and GSM systems while the algorithm computes the optimal resources for the highest achievable throughput.","PeriodicalId":131597,"journal":{"name":"2022 International Conference on Broadband Communications for Next Generation Networks and Multimedia Applications (CoBCom)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134477413","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}

Satellites always need to exchange data. This data is passed through a chain of components representing the communication chain. On ESA's OPS-SAT mission software experiments are running on the processing platform. They have to be uploaded and their results downloaded. Therefore, the communication chain needs to support high bandwidths to enable these operations. Moreover, OPS-SAT's communication chain is reconfigurable and can be switched between a nominal and a bypass mode. This bypass mode enables direct access for a software experiment to the radios. There are no more intermediate processing steps and thereby a raw interface to the data-link layer is provided. After OPS-SAT's launch all peripherals were commissioned as it is done for every satellite. However, since the ground segment requires standards compliance, this bypass mode needed a dedicated commissioning strategy to prove its correct operation. Here, we report the chosen commissioning approach on the ground and in space together with the results. Further, this shows a unique way of commissioning a satellite's communication chain. Moreover it provides a motivation for employing more advanced test scenarios, especially in constrained conditions, to extend the possible test coverage.","PeriodicalId":131597,"journal":{"name":"2022 International Conference on Broadband Communications for Next Generation Networks and Multimedia Applications (CoBCom)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133688627","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}
