String matching algorithms have important roles in various real world areas such as web and security applications. In this work, we are interested in solving regular expression matching hence a more general form of string matching problem targeting especially the field of network intrusion detection systems (NIDS). In our work, we enhance a non-deterministic finite automata (NFA) based method on FPGA considerably. We propose to use a matching structure that processes two consecutive characters instead of one in order to yield better memory utilization and provide a novel mapping of this new architecture onto FPGA. The amount of digital circuitry needed to represent the NFA is reduced due to having less number of states and less number of LUTs in the devised 2-character regex matching process. An evaluation study is performed using the well-known Snort rule set and a sizable performance improvement is demonstrated.","PeriodicalId":211570,"journal":{"name":"2021 International Conference on Computer, Information and Telecommunication Systems (CITS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126307220","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, RIS-assisted energy-efficient hybrid precoding schemes are introduced as a promising technology that can achieve a transmission in an intelligent way. In addition, an RIS-assisted machine learning (ML) inspired energy-efficient hybrid precoding scheme that requires low-cost and energy-efficient switches and inverters is considered, where the adaptive cross entropy (ACE) optimization algorithm is employed to find the corresponding optimal precoding weights. Besides, imperfect channel state information (CSI) in both the source-to-RIS channel and RIS-to-destination channel links is assumed to be known. Extensive simulations have been conducted to evaluate the effect of imperfect CSI on the achievable sum-rate and the energy efficiency of the proposed RIS-assisted hybrid precoding schemes. Additionally, the performance of the proposed hybrid precoders is compared to that of the conventional hybrid precoding schemes. The results reveal that the proposed hybrid precoding architectures outperform the conventional schemes with large number of reflecting elements, and the performance is significantly degraded in the presence of imperfect CSI.","PeriodicalId":211570,"journal":{"name":"2021 International Conference on Computer, Information and Telecommunication Systems (CITS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122470576","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}

They need to upgrade to solve the complex problems that are faced by the different applications. The healthcare industry is one of them. In the current healthcare industries, the patient’s information is stored in the central cloud servers, and the third party (TP) is required to share these details among the service providers. As a result, sharing information without adopting TP in a distributed manner is a challenging task. The distributed ledger technology blockchain has the potential to resolve the problems mentioned above. The blockchain provides the immutability, transparency, and traceability of records where the records are distributed among the many nodes. This article first presents the various problems of the current electronic medical record (EMR) system, discusses the importance of blockchain in EMR systems, and finally summarizes the existing approaches with their future scopes. Based on it, this paper proposed a novel architecture for a blockchain-enabled secure sharing of health records. In addition to it, possible research directions with the relevant security attacks for blockchain systems are also highlighted in the paper.","PeriodicalId":211570,"journal":{"name":"2021 International Conference on Computer, Information and Telecommunication Systems (CITS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122476074","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 contrast with existing IP algorithms, DPIRFE forecasts the future trajectory of a mobile IoT device by using machine learning and dynamically adjusts the positioning interval based on the reciprocal instantaneous forecasting error, thereby dynamically trading off transmit energy consumption against forecasting error. We compare the performance of DPIRFE with respect to the total transmit energy consumption and the average forecasting error against Constant Positioning Interval (CPI) and Positioning Interval based on Displacement (PID) algorithms. Our results show that DPI-RFE significantly outperforms both of these benchmark algorithms with respect to transmit energy consumption while achieving a competitive average forecasting error performance. These results open the way to the design of machine learning based trajectory forecasting algorithms that can be utilized for energy-efficient positioning in next-generation wireless networks.","PeriodicalId":211570,"journal":{"name":"2021 International Conference on Computer, Information and Telecommunication Systems (CITS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132865487","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 Stackelberg game is used to assign the spectrum to devices connected with small cell base station (SBS), and the coalition formation game is used to allocate the spectrum between device-to-device (D2D) communication devices. Two utility functions have been proposed and through these functions the network operator assigns the required spectrum to the devices.
