In our simulation scenarios, primary users and secondary users exploit TDMA as a medium access control protocol. We have designed a network environment in Riverbed (OPNET) simulation software that consists of primary users, secondary users, and base stations. In our network model, secondary users sense the spectrum and inform the base station about empty channels. Then, the base station decides accordingly which secondary user may exploit the empty channel. Energy detection technique is employed as a spectrum sensing technique because it is the best when information about signal of primary user is obtained. Besides, different number of users is selected in simulation scenarios in order to achieve accurate delay results. Comparing analytical model with simulation results, we have shown that delay analysis of our system model is reliable and correct.","PeriodicalId":433594,"journal":{"name":"2016 XIth International Scientific and Technical Conference Computer Sciences and Information Technologies (CSIT)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127848069","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 order to prepare the conditions for achieving \"almost zero\" man-made damage due to rapid reduction of technogenic pollution (emissions, discharges, waste) and the use of \"closed\" technologies for collecting, processing, utilizing technogenic waste, the technosoliton model has been proposed. This will increase the effectiveness of state regulation of the phenomenon, provide appropriate allocations for their eradication and compensation.","PeriodicalId":433594,"journal":{"name":"2016 XIth International Scientific and Technical Conference Computer Sciences and Information Technologies (CSIT)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115315534","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 distribution is normally performed by moderators. The content distributional subsystem shortens the time and diminishes the resource usage for the further electronic content commerce systems (ECCS) functioning. The distributional process expects several stages to be processed: the distributional objects list formation (e.g. articles, software, books or digests); the estimation of the content distributional criterions/features from the received list (the content uniqueness percent, the amount of the content requests, the users' mark and the review time); the content authors ratings creation; the content's parameters evaluation for the purpose to use it within the distributional process. The listed criterions are not of the same importance and significance within their total analysis and the computing of the content authors' work quality composite mark. The content contains the thematics and the digest. The content distributional system selectively sends digests to authors according to their work quality ratings. The increase in the content volume causes the proper quality and productivity evaluation of the very content author. The increase in the evaluation criterions allows covering the broader aspect range of any author's/moderator's work.","PeriodicalId":433594,"journal":{"name":"2016 XIth International Scientific and Technical Conference Computer Sciences and Information Technologies (CSIT)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130998938","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}
