On the one hand, to ensure a bounded rendezvous time to exchange data for the asynchronous slotted protocol, the wake-up schedules intersect regardless of rotations. On the other hand, they are designed to minimize worst-case latency for given duty cycles to be energy-efficient. We formulate the problem as a block design problem and devise the optimal asymmetric wake-up schedules based on the theoretical foundation. Simulation results demonstrate that the proposed schedules outperform various existing schedules of different kinds.","PeriodicalId":352596,"journal":{"name":"2021 2nd Information Communication Technologies Conference (ICTC)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129127374","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}

Facing the fact that TCP/IP is deeply entrenched in the current Internet architecture, NDN has made slow progress in industrial promotion. Meanwhile, new architectures represented by SDN, P4, etc., provide a flexible and programmable approach to network research. As a result, a centralized NDN routing mechanism is needed in the scenario for network integration between NDN and TCP/IP. Combining the NLSR protocol and the P4 environment, we introduce an efficient NDN routing mechanism that offers extensible NDN routing services (e.g., resources-location management and routing calculation) which can be programmed in the control plane. More precisely, the proposed mechanism allows the programmable switches to transmit NLSR packets to the control plane with the extended data plane. The NDN routing services are provided by control plane application which framework bases on resource-location mapping to achieve part of the NLSR mechanism. Experimental results show that the proposed mechanism can reduce the number of routing packets significantly, and introduce a slight overhead in the controller compared with NLSR simulation.","PeriodicalId":352596,"journal":{"name":"2021 2nd Information Communication Technologies Conference (ICTC)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124497861","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}

Although the DSS technology has many advantages above, the introduction of DSS in the network will introduce a lot of interference between different systems, which will affect the network performance. In this paper, through the analysis of the technical scheme of DSS based on the overhead calculation, the performance of various communication systems under DSS networking is theoretically evaluated. At the same time, 20 base stations are arranged in the outdoor experimental site. The call quality test of the DSS network is used to verify the influence of interference between different systems on the performance of various communication modes. Finally, the throughput of various communication modes under the DSS network is given through the drive test. At present, there is no literature to verify the networking performance of 20MHz DSS. This paper has great reference value for operators who need to deploy 4/5G cooperative networking in Sub 3GHz due to the shortage of spectrum resources.","PeriodicalId":352596,"journal":{"name":"2021 2nd Information Communication Technologies Conference (ICTC)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115859162","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 vibration signal is decomposed into several intrinsic mode functions (IMFs) with ensemble empirical mode decomposition (EEMD) to eliminate the random noise interference from the original vibration signal. It is vital to choose sensitive features from both the time and frequency domain of IMF components with importance rank by using RF. Then PCA is conducted to eliminate the correlation among sensitive features. On this basis, this paper utilizes LSTM neural network to get better diagnosis performance in complicated working conditions and hybrid faults. Comparing with the traditional feature extraction method, RF-PCA can get fewer but more representative characteristics. At the same time, the introduction of the LSTM neural network can provide a simple and practical resolution for rolling bearing fault diagnosis.","PeriodicalId":352596,"journal":{"name":"2021 2nd Information Communication Technologies Conference (ICTC)","volume":"abs/2206.12198 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131129344","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}

This feature created unlimited possibilities for operators to achieve 5G NR coverage in the low frequency band of the indoor distribution system. At the same time, the dynamic spectrum sharing of the indoor distribution system also helped operators to save the high cost of frequency re-farming or purchasing new spectrum licenses, which also helped to smoothly transition the LTE users base to 5G and introduce standalone network faster. The background, deployment and key technical solutions of dynamic spectrum sharing were discussed in this paper. The main technical solutions included MBSFN subframe solution, LTE punching solution and NR punching solution. In addition, the 2.1G 20MHz dynamic spectrum sharing experiment of the indoor distribution system was also carried out. Experiments were carried out at multiple sampling points under NR 20MHz, LTE 20MHz and DSS 20MHz scenarios. The experimental data can provide certain reference value for the subsequent smoothing performance of the indoor distribution system, and also provide a direction for the further research on dynamic spectrum sharing technology with larger bandwidth.","PeriodicalId":352596,"journal":{"name":"2021 2nd Information Communication Technologies Conference (ICTC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122998308","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}

To enhance real-time guarantees, TSN adopts several shaping Credit-Based Shaping, Asynchronous Traffic Shaping (ATS), Burst-Limiting Shaper (BLS), and scheduling mechanisms such as Time Aware Shaper (TAS) and numerous types of traffic are integrated. In modern industries, the increasing number of traffic and data is causing latency to increase significantly. To minimize the end-to-end delay, it is highly required to have lossless compress data. This paper proposes some pre-existing lossless compression algorithms (Huffman, LZW, RLE), which are well suited for the TSN network. It can improve the end-to-end delay despite increasing data, and it is applicable for the worst-case scenarios as well. Moreover, the focus of this research is confined to the CBS shaping mechanism. For the validation of our statement, various traffic such as Control Data Traffic (CDT), Audio & Video Bridging (AVB) class A, AVB class B, and best-effort have been simulated using OMNeT++. Comparisons are shown in terms of end-to-end delay between the compressed and the uncompressed data, and end-to-end delay has been improved for all classes.","PeriodicalId":352596,"journal":{"name":"2021 2nd Information Communication Technologies Conference (ICTC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123505953","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}
