The essence of the model is that the software is divided into logical modules, that is, by its purpose. The architecture of the Web-system is designed so that the modules contain as little logic as possible, because the main task of load redistribution is to support the system in balance. The second requirement for the software architecture is to avoid strong connectivity. Therefore, it is necessary to divide the system into small modules that work with one or a small number of «parent» modules. In the developed model, the modules are isolated from each other and do not have a general condition, but between them you can establish communication and receive notifications about their condition. Asynchronous message exchange is used for interaction of modules. An important aspect of the research is that additional free resources can be found within the existing capabilities of the Web-system.","PeriodicalId":6764,"journal":{"name":"2019 IEEE International Scientific-Practical Conference Problems of Infocommunications, Science and Technology (PIC S&T)","volume":"15 1","pages":"147-152"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83301389","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 method for analyzing the maximum entropy was software implemented and the results of its work showed high-quality attack detection. The method can detect various attacks with a probability of about 94%, while false-positive values did not exceed 10%.

It is established that both in literature and in practice insufficient attention is paid to search for and design of such simple adaptation algorithms that do not require presence of the reference signal. Gradient method of adaptation is considered and its limitations are exposed. It is shown that the gradient method requires a reference signal that can be presented as the signal in a selected antenna element or a reference signal generated in the antenna array. A simple algorithm of antenna array adaptation is deduced that operates in the absence of the reference signal. Computer simulation of adaptive antenna arrays with the designed algorithm in different situations is carried out, which singles out inherent deficiency in the algorithm. Improvements to eliminate this deficiency are offered. High performance of the improved gradient algorithm is confirmed in difficult interference environments.","PeriodicalId":6764,"journal":{"name":"2019 IEEE International Scientific-Practical Conference Problems of Infocommunications, Science and Technology (PIC S&T)","volume":"1 1","pages":"635-638"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73890538","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}
