Through the contention window, waiting time required before sending data can be determined. Therefore, the adjustment of the competition window is an important key that affects network transmission performance. At present, most related researches anchored on wireless local area networks (WLAN) to design channel competition backoff algorithms. These methods all consider the transmission collision problem caused by the increase of the number of nodes to improve the performance, which it is uncertain whether these methods can be applied on Wireless Home Area Network (WHAN) that contains fewer nodes. Through experimentation with different numbers of nodes and different contention window sizes, this study found a collision rate range with superior efficiency, and thus proposed a backoff algorithm for Home Area Network (BA-HAN). The size of the competition window is adjusted based on the size of the contention window to achieve the performance improvement and reduction of the collision rate. According to the experimental result, the BA-HAN algorithm is superior to related channel competition mechanisms (EIED, LILD, ELBA, and CRBA).","PeriodicalId":153290,"journal":{"name":"2020 2nd International Conference on Computer Communication and the Internet (ICCCI)","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123246400","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}

On the communication side however, all scenarios can be reduced to similar requirements. I4.0 communication requires real-time capability, reliability and interconnectivity of many clients. The realization of these requirements is already made possible by the IEEE standardized TSN technology. A key enabler for the realization of these requirements is a common time understanding of all involved instances, in order to coordinate the complexity arising in such a scenario. For this purpose, clock synchronization is an essential component of TSN. However, there is another essential feature that many I4.0 use cases have in common, which is the spatial dynamics of clients that only wireless communication can provide. This paper presents an approach based on WLAN, which is also able to meet these requirements. The essential points of clock synchronization as used in TSN are analyzed and transferred to WLAN and further concepts and optimizations will be introduced. These concepts are evaluated and analyzed in simulations. The result is a communication concept, which is able to exceed the performance of wired TSN as shown by various KPIs.","PeriodicalId":153290,"journal":{"name":"2020 2nd International Conference on Computer Communication and the Internet (ICCCI)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125448706","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 proposed hardware sharing architecture supports two sizes transforms, i.e. 4×4 and 8×8, for H.264/AVC, AVS, VC-1, MPEG-1/2/4, HEVC, and VP8 video coding standards. The proposed design supports the hardware sharing based multiple forward and inverse transforms. Firstly, the transform matrices are replaced with the well-known matrix expressions, and then the entire transform matrices are decomposed to several sparse matrices. Thus, the computational complexity, the chip area, and the computational time are reduced. By the proposed matrix decomposition algorithm, the sparse transform matrices are decomposed to small ones further for ease and efficient hardware shares. Compared with the individual implementation without shares, the proposed 1-D hardware sharing based multiple forward and inverse transform design reduces additions by 83.5% and shift operations by 60.8%. The gate counts of the hardware sharing based 1-D forward and inverse transform design are 22.2K. The proposed hardware sharing based 2-D transform requires 57.3K gates. The operational frequency is 110.8MHz to satisfy the Full HD (1920×1080@60Hz) specification, and the maximum operational frequency can be up to 200MH.","PeriodicalId":153290,"journal":{"name":"2020 2nd International Conference on Computer Communication and the Internet (ICCCI)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129027485","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}
