It represents an efficient technique for approximate inference which becomes accurate when both rows and columns of the measurement matrix can be treated as sets of independent vectors and both dimensions become large. It has been shown that the fixed points of GAMP correspond to extrema of a large system limit of the Bethe Free Energy (LSL-BFE), which represents a meaningful approximation optimization criterion regardless of whether the measurement matrix exhibits the independence properties. How-ever, the convergence of (G)AMP can be notoriously problematic for certain measurement matrices and the only sure fix so far is damping (by a difficult to determine amount). In this paper we revisit the GAMP algorithm by rigorously applying an alternating constrained minimization strategy to an appropriately reparameterized LSL-BFE with matched variable and constraint partitioning. This guarantees convergence, at least to a local optimum.","PeriodicalId":206258,"journal":{"name":"2022 IEEE International Mediterranean Conference on Communications and Networking (MeditCom)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128561586","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}

One solution to deal with this interference is implementing power control schemes. However, solving the power allocation in denser wireless networks becomes challenging due to the computational complexity involved and the complete Channel State Information (CSI) required. One alternative to address these challenges is implementing Deep Reinforcement Learning (DRL) models, which may find solutions faster and with fewer CSI requirements. In this work, we implement a Centralized Training scheme for training a DRL model over a wireless network environment consisting of different tasks (i.e., UE location and CSI). Training over various tasks may degrade the performance of older tasks. Therefore, to retain the knowledge of older tasks, we implement a memory-based strategy to split the buffer for storing relevant experiences based on the action-space exploration. Additionally, we implement a rehearsal method for reusing samples of similar environments. The results show a learning performance improvement when learning newer tasks. Further, the degradation due to learning multi-task is reduced compared to classic DQN models with FIFO buffer.","PeriodicalId":206258,"journal":{"name":"2022 IEEE International Mediterranean Conference on Communications and Networking (MeditCom)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125569439","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}

Recently, in the context of European research and innovation actions, the term NetApp was introduced. A NetApp, in the context of the 5G System, is defined as a set of services that provide certain functionalities to the verticals and their associated use cases. While there is no specific standard for describing the NetApp concept, the ETSI NFV model is adopted to describe the delivery and deployment of NetApps. This work presents an approach for automating the deployment and testing of NetApps in the context of the 5G system. The envisaged process focuses on innovations related to the operation of experiments and tests across several domains, providing software support tools for Continuous Integration and Continuous Deployment (CI/CD) of NetApps and their artifacts in a secure and trusted environment.","PeriodicalId":206258,"journal":{"name":"2022 IEEE International Mediterranean Conference on Communications and Networking (MeditCom)","volume":"51 Pt 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126235846","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}

However, one intrinsic characteristic of IoT is the heterogeneity of the IoT devices that are continuously connected and disconnected, creating a highly volatile communication environment. In addition to that, new types of IoT devices are constantly manufactured making a supervised categorization approach not applicable due to the lack of historical data. Nonetheless, the classification or type identification of the IoT devices is important for the management and the decision making of the IoT applications, and can be used for traffic characterization, density prediction, network planning and security reasons among others. Accordingly, in this paper we propose for the first time an unsupervised machine learning methodology for the IoT device categorization that leverages traffic characteristics obtained at the network level. To this end, we tackle the limitation of requiring an annotated dataset, while our model could also work efficiently with new and not previously detected IoT devices. To do so, we experimentally evaluate our approach using two clustering algorithms namely, the K-Means and the BIRCH in a real dataset. The experimental evaluation presents promising results that enhance the applicability of unsupervised approaches for the IoT device categorization problem.","PeriodicalId":206258,"journal":{"name":"2022 IEEE International Mediterranean Conference on Communications and Networking (MeditCom)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130706006","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}

Thanks to NFV, operators are given a much greater flexibility, as these VNFs can be deployed as virtual nodes and chained together to form Service Function Chains (SFCs). An SFC represents a set of dedicated virtualized resources deployed to provide a certain service to the consumer. One of its most important performance requirements is availability. In this paper, the availability achieved by SFCs is evaluated analytically, by modelling several protection schemes and given different availability values for the network components. The cost of each protection scheme, based on its network resource consumption, is also taken into account. Extensive numerical results are reported, considering various SFC characteristics, such as availability requirements, number of NFV nodes and availability values of network components. The lowest-cost protection strategy, in terms of number of occupied network components, which meets availability requirement, is identified. Our analysis demonstrates that, in most cases, resource-greedy protection schemes, such as end-to-end protection, can be replaced by less aggressive schemes, even when availability requirements are in the order of five or six nines, depending on the number of elements in the service function chain.","PeriodicalId":206258,"journal":{"name":"2022 IEEE International Mediterranean Conference on Communications and Networking (MeditCom)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129220148","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}
