We previously proposed an architecture of information-centric elastic optical transport networks called i-CEON for efficient large-scale content delivery. In i-CEON, we deploy in-network cache functions (ICFs) to reduce redundant use of network resources. The key lies in how to adequately place replicated content in ICFs so as to improve the efficiency of optical paths. In our previous work, we formulated the joint optimization of such a problem as mixed integer linear programming. Though the previous method always finds the optimal solutions, it fails to ensure network scalability and quick responsiveness. To overcome this issue, we develop a nearly optimal heuristic algorithm called NetLCP that improves efficiency of network resources with practical computational overhead. We conducted intensive numerical experiments and demonstrated that NetLCP always found nearly optimal solutions and indicated fewer than 10% of approximation errors compared with the optimal solutions.","PeriodicalId":6802,"journal":{"name":"2021 IEEE Globecom Workshops (GC Wkshps)","volume":"1 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90185359","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 parameters of the EG-GNN are trained in an unsupervised manner by minimizing the overall packet loss probability, including the decoding error probability of short packet transmissions, the collision probability of random access, and the processing delay violation probability in edge servers. By representing the wireless network by a bipartite graph with base station nodes and device nodes, we apply the EG-GNN to user association, where the \"gate\" of an edge is defined as the probability that a device will associate with a BS. The values gates are determined by a fully connected neural network at each device node. To improve the training efficiency, analytical results in wireless communications and queueing theory are exploited to update node features. Simulation and analytical results demonstrate that the proposed EG-GNN approach outperforms existing benchmarks in terms of overall reliability with linear complexity.","PeriodicalId":6802,"journal":{"name":"2021 IEEE Globecom Workshops (GC Wkshps)","volume":"1998 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88194291","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}

In this paper, we investigate the effect of the multi-polarization on the performance of the massive multiple-input multiple-output (MIMO) system. Traditional MIMO channel modeling and performance analysis methods are based on the plane wavefront, wide-sense stationary, and small-angle assumptions, which is not suitable when the scatterers are distributed within the Rayleigh distance of the antenna arrays for the massive MIMO system. To this end, we first propose a multi-polarized stochastic channel model by considering the antenna pattern and the channel polarization properties. The parabolic wavefront and environment evolution effects are also incorporated into the proposed model to accurately characterize the near-field effect and non-stationary characteristics of the massive MIMO system. We then derive the analytical and closed-form expressions of the spatial cross-correlation function (SCF) to evaluate the statistical channel characteristics of the multi-polarized system. Numerical results show an excellent agreement between the simulated channels and the theoretical ones in terms of the SCF. Besides, simulation results also indicate that it is beneficial to reduce the correlation between antennas and increase channel capacity by employing the multi-polarized antennas, especially for compact antenna arrays.","PeriodicalId":6802,"journal":{"name":"2021 IEEE Globecom Workshops (GC Wkshps)","volume":"76 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78051868","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 interference assessment between NTN and 5G evolution services in U6G is one of key issues needed to be considered before the large-scale deployment of U6G band in 5G evolution. Therefore, the clutter loss (CL) model is pivotal to the different systems co-existence evaluations. ITU-R has issued a Recommendation (ITU-R P.2108) giving CL model for the estimation of clutter loss at three different terminal environments for varied frequency range. However, the clutter loss model for NTN environment in ITU-R P.2108 only supports the frequency range from 10G Hz to 100 GHz and can be applicable to the terminal heights of below 5 m. In this paper, the clutter loss measurement and simulation below 10 GHz for NTN scenario has been conducted at different terminal heights on the ground in urban and suburban environments. Furthermore, the CL model is extended to the frequency bands below 10G Hz. In the proposed CL model, the terminal height is considered, which has high impact on the CL results. Taking 4-6m base station height as a baseline, we provide different ground station height results analysis based on both real measurement and ray-tracing simulation. An additional adjusting factor α is modelled to reflect different antenna height characteristics. The CL model will be adopted to the NTN and 5G evolution systems co-existence evaluation.","PeriodicalId":6802,"journal":{"name":"2021 IEEE Globecom Workshops (GC Wkshps)","volume":"20 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74423909","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}
