There is a growing consensus in the industry that the future architecture is a data-centric fabric which can better integrate the function of computation, storage and network. In order to reduce the pressure on CPUs in data centers and further facilitate the transformation of the entire architecture towards higher flexibility and efficiency, this paper presents a SmartNIC-based offloading framework for storage pooling (SOSP) by leveraging the functionality of SmartNICs to offload both the local and remote storage services from CPUs. Our experiments show that the SmartNIC-based solution SOSP can increase the I/O random Read/Write operation performance by around 20-25% and 13-15% respectively, and at the meantime, free up host CPU cores by saving 16.7% virtual cores compared to the solution without using SmartNICs.","PeriodicalId":360718,"journal":{"name":"Proceedings of the 2022 9th International Conference on Wireless Communication and Sensor Networks","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129493718","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 translates indirectly into a significant improvement in the quality of life. However, there is a price to be paid; this evolution is associated with the emergence of many threats, which seem to develop even faster and are often not realized by professionals. Striving to maximally increase the computational power resulted in vulnerabilities on the level of the very processors. These vulnerabilities are mostly associated with the mechanisms of speculative execution and cache use in modern processors. Some of them came to light after many years. An example here might be Spectre vulnerabilities class which has been found in most Intel's processors (and not only) from 2006 and which was disclosed as late as in 2017. In the recent years many of such security vulnerabilities arose and according to many experts this is just the beginning. This article presents our evaluation of Spectre version 3 (Meltdown) vulnerability. It is just a prelude to further research regarding low-level vulnerabilities we are going to pursue.","PeriodicalId":360718,"journal":{"name":"Proceedings of the 2022 9th International Conference on Wireless Communication and Sensor Networks","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121426734","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}

And the morphological cascade filter and Gaussian filter are constructed in the denoising and smoothing pre-processing of the laser spot image. In order to make full use of the intensity distribution of laser spot, the threshold range is determined by the Otsu algorithm and maximum light intensity, which is non-uniformly segmented by exponential function to obtain a series of binary spot images. After the center of light spot is initially determined by the centroid method, a series of center samples are obtained by Hough transform on the edge extraction image, and then the clustering center is obtained by K-means algorithm, at last the actual coordinate of the laser spot center is obtained through the relationship of the coordinate functions fitted by BP neural network. The proposed algorithm is tested on the coordinate screen of the track trolley, and its error can meet the requirements of the in-site survey.","PeriodicalId":360718,"journal":{"name":"Proceedings of the 2022 9th International Conference on Wireless Communication and Sensor Networks","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125392999","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}

By simulating the light intensity distribution, phase variation and the ITU-R model for different turbulence cases, the characteristics of the Laguerre Gauss beam are analyzed for different values of the Laguerre Gauss beam in this paper, i.e., the angular modulus. This paper finds that, at the on-axis position, the scintillation of Laguerre Gauss beams with zero angular modulus is theoretically lower than that of the fundamental Gauss beams, while the scintillation value gradually decreases as the radial modulus rises, and at the off-axis position, the Laguerre Gauss beams have the scintillation value is generally higher than that of the fundamental Gaussian beam.","PeriodicalId":360718,"journal":{"name":"Proceedings of the 2022 9th International Conference on Wireless Communication and Sensor Networks","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115606117","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 the considered scenario, two D2D users share the downlink spectrum resource with two cellular users. When the two D2D users transmit signals to each other, they also act as relays between the base station (BS) and the cellular users so that the cellular users can leverage the redundant capacity of the two full duplex D2D users. To optimize the performance of the scheme, the power allocation is optimized by considering the impact of residual self-interference at full duplex radios and the quality of services (QoS) requirement for both cellular users and D2D users. The simulation results show that, compared to the existing research scheme, the proposed scheme can achieve larger sum channel capacity for the transmission of cellular users, and it can also achieve larger average system throughput at high signal to interference plus noise ratio (SINR) region.","PeriodicalId":360718,"journal":{"name":"Proceedings of the 2022 9th International Conference on Wireless Communication and Sensor Networks","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125173428","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}
