The congestion of a bottleneck link can be significantly reduced when byte caching is implemented in both ends of the link. We propose four techniques to improve the original byte caching method. Two of these techniques offer better fingerprint sampling for caching and the other two offer better management of fingerprints to increase the likelihood of matching. The implementations of these techniques improve the compression ratio of the original byte caching method by 10-20%, which is a significant boost to the efficiency of byte caching methods. Proposed techniques can be implemented with minimal to moderate overhead compared with the original byte caching method.","PeriodicalId":162582,"journal":{"name":"2015 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126326744","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}

A widely used performance prediction method for coded multicarrier transmissions applying iteratively decoded error correction codes is based on the employment of the mean mutual information of the coded bit. A precise knowledge at the transmitter site of the log likelihood ratios distribution at the receiver facilitates the accurate performance prediction and unambiguous modeling of the decoder's behavior in a multiphase transmission. This paper proposes an analytical method to characterize the distribution of the received bits log likelihood ratios using a limited number of parameters. The paper also evaluates the accuracy provided by the proposed theoretical method by comparing its results to the ones obtained from measurements. The performance evaluation shows that the proposed method provides good accuracies both for transmissions over Gaussian and frequency-selective channels.","PeriodicalId":162582,"journal":{"name":"2015 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123981779","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 are also useful for physical layer security of transmissions over the broadcast channel with confidential messages. Classical design approaches aim at optimizing the performance over all the protection classes, independently of the separation between them. We instead propose a solution to improve the performance over the most protected bits, at the expense of performance over the least protected ones. This allows to design coded modulation schemes with largely unequal error protection. We also consider the use of high order modulations, and propose a technique to study the performance over each protection class in the asymptotic regime of infinite code length.","PeriodicalId":162582,"journal":{"name":"2015 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132396323","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}

Depending on the actual approach used to allocate transmit power over available channels, mutual interference may affect user performance. Three types of horizontal spectrum sharing scenarios will be outlined in the paper, which can be reached through different user strategies for power allocation that can be more or less greedy in terms of channel use. The impact of such strategies for power allocation on user rates and total system throughput in dense and sparse spectrum sharing scenarios will be discussed in the paper. The discussion is illustrated with numerical results obtained from simulations, which show that less greedy approaches result in a more efficient spectrum sharing scenarios than the more greedy ones.","PeriodicalId":162582,"journal":{"name":"2015 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130727956","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}

Current IP-level mobility protocols such as Mobile IPv6 or Proxy Mobile IPv6 (PMIPv6) have difficulties meeting the stringent handover delay requirements. Besides, when there are many candidate networks, i.e., multiple destination networks, can be selected, a proper selection of Mobile Node's destination network can improve the handover delay and packets loss. In order to reduce the limitation within heterogeneous networks, the IEEE 802.21 Media Independent Handover Services (MIH) was developed. MIH enables the optimization of handover between heterogeneous networks. In this paper, A Load-Considered Fast Media Independent Handover control scheme for Proxy Mobile IPv6 (LC-FMIH-PMIPv6) is proposed to integrate the robustness of MIH services and a proper selection of MN's destination network to improve the handover performance over the PMIPv6 environment.","PeriodicalId":162582,"journal":{"name":"2015 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128367055","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}

Most existing CRN routing schemes focus on building a route that optimizes a single aspect of a network's performance, such as minimizing interference for primary users, or reducing the propagation delay or hop count. They do not consider the overall transmission performance for secondary users. In this work, our objective is to maximize a system's long-term estimated throughput. To this end, we propose two routing schemes, called TBR and A-TBR, for different types of cognitive radio interfaces. The schemes establish routes by considering multiple system factors, such as the interference rate and the transmission bitrate, simultaneously. The results of simulations show that the schemes yield higher throughput than existing approaches and the transmission delay is acceptable. To the best of our knowledge, this is the first work that proposes a solution to the long-term performance of CRNs.","PeriodicalId":162582,"journal":{"name":"2015 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114183396","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 analytical model of dual-band filter has been developed, accounting for two bands simultaneously. The accuracy of the presented analytical model has been examined by simulation results using finite element method as well as by the conducted experiment, showing very good consistency.
