While it is often considered that fully or partially overlapping frame transmissions lead to collision and loss of both frames, in reality, sometimes at least one frame can survive if its receive power is higher than that of another frame by some predefined value. The ability of a device to receive the stronger frame if it comes later than the weaker one is called capture effect. For various devices, the capture effect is manifested in different ways. Specifically, we can distinguish preamble and frame body capture effects. The core contribution of the paper is an original testbed which can be used to study the capture effect for numerous off-the-shelf devices in massive experiments. With this testbed, we show that the majority of existing devices follow the standard and do not capture stronger frames during reception of the body of a weaker frame, which limits the performance of Wi-Fi networks in scenarios with hidden stations.","PeriodicalId":351647,"journal":{"name":"2018 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126390822","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}

Despite of its ability to fulfil the PHY layer constrains of those technologies (i.e. high-power efficiency and low hardware complexity), the 1-bit ADC MIMO-CEM received signal is exposed to severe quantization distortion. This quantization distortion is sorely affected on the efficiency of the MIMO-CEM channel estimation since, estimation operation depends on the received signal amplitude information. This is in turn adds serious threat to the MIMO-CEM decoder quality which, is depending on the accuracy of the estimated channel. Therefore, a low complex and spectral efficient MIMO-CEM channel estimation algorithm is proposed in this paper. In which, the MIMO-CEM channel sparsity is exploited to propose an adaptive compressive sensing (ACS) channel estimation algorithm to cope with the 1-bit ADC severe quantization distortion. In the proposed ACS, the sensing (measurement) matrix is adaptively updated (changed) and resized in order to speed up (low computational complexity) the channel estimation process with minimum error constrain at low preamble signal length. However, the proposed algorithm is spectrally efficient (very low preamble signal length) and it is computational complexity is very low compared to the recently MIMO-CEM channel estimators. Eventually, the proposed algorithm introduces computational complexity reduction up to 90 % and it gives up to 72 % spectrum saving compared to the conventional MIMO-CEM channel estimator.","PeriodicalId":351647,"journal":{"name":"2018 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124554679","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 F-QSM is a class of space modulation techniques (SMTs) that harness the spatial positions of the transmit antennas in the transmit antenna array to fulfill high data rates. However, the data rates of most of SMTs are restricted to be logarithmically proportional to the number of transmit antennas. This logarithmic proportion is considered a pivotal crisis of most of SMTs, as it bottlenecks the enhancement in their data rates with the increment in the number of transmit antennas. Accordingly, the proposed F-QSM vanquishes this crisis by using a novel transmission mechanism to acquire a linear proportion between the achievable data rate and number of transmit antennas. This linear proportion, enables the proposed F-QSM to achieve a higher data rate than the conventional SMTs and by using a lower number of transmit antennas. In this paper, a mathematical framework for assessing the average bit error rate (ABER) performance of the proposed F-QSM is investigated thoroughly. Moreover, the receiver computational complexity of the proposed F-QSM is evaluated and tested reference to the computational complexity of the conventional SMTs at different number of transmit antennas. Simulation results reveal the effectiveness of the analytical analysis and corroborate the surpass of the proposed F-QSM in terms of ABER performance and achievable data rate at the expense of increasing receiver computational complexity compared to the conventional SMTs.","PeriodicalId":351647,"journal":{"name":"2018 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123626426","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}

As the energy costs contribute largely to the overall costs in networks, energy efficiency is a significant design requirement for modern networking mechanisms. However, designing energy efficient solutions is complicated since there is a trade-off between energy efficiency and network performance. In this paper, we propose traffic proportional energy efficient framework for SDN and heuristics algorithm that maintains the tradeoff between efficiency and performance. We also present IP formulation for traffic proportional energy efficiency problem. Comprehensive experiments conducted on Mininet emulator and POX controller using Abilene, Atlanta, and Nobel-Germany real-world topologies and traffic traces show that our approach saves up to 50% energy while achieving a performance closer to the algorithms prioritizing performance.","PeriodicalId":351647,"journal":{"name":"2018 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128333418","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}
