A secure encryption algorithm is considered energy efficient if it uses a minimum number of CPU operations. In this paper we use numerical calculations to analyze the energy consumption for a class of encryption algorithms. We compute the number of arithmetic and logical instructions in addition to the number of memory access used by each of the algorithms under study. Given some information about the microprocessor used in encryption, we can compute the energy consumed per each instruction and hence compute the total energy consumed by the encryption algorithm. In addition, we use computer simulations to compare the energy loss of transmitting encrypted information over the Wireless channel. Therefore, in this paper we introduce a comprehensive approach where we use two approaches to analyze the energy consumption of encryption algorithms.","PeriodicalId":247495,"journal":{"name":"2014 IEEE Radio and Wireless Symposium (RWS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128716303","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 idea is to utilize multiple sinusoidal waves swept over the UWB bandwidth. A two-dimensional MUSIC algorithm was adopted to estimate the respective DOD and DOA at each frequency component. Histograms of the estimated angles were formulated to obtain the peak DOD and DOA. Simulation results demonstrated that the combination of the 2D-MUSIC and the angle histograms resulted in precise estimation of DOD and DOA. Indoor experiments also validated the proposed technique.","PeriodicalId":247495,"journal":{"name":"2014 IEEE Radio and Wireless Symposium (RWS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125548071","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 wideband input-impedance matching was achieved by taking advantage of the resistive shunt-shunt feedback in conjunction with a parallel LC load to make the input network equivalent to two parallel RLC branches, i.e., a second-order wideband BPF. The wideband output matching was also achieved by making the output network equivalent to a second-order wideband BPF. Theoretical analysis shows that both the frequency response of input matching and NF can be described by second-order functions with quality factors as parameters. The LNA dissipates 9.96 mW and achieves low and flat NF of 3.24±0.5 dB and high and flat S21 of 12.02±1.5 dB for frequencies 1.9~22.5 GHz.

That becomes a key problem in the gateway design, since its cost and energy consumption increase with the number of implemented technologies. This cost and energy can be reduced by using a reconfigurable gateway to perform the biggest part of signal processing digitally, as it is done in Software-Defined Radio (SDR). As several received signals should be simultaneously digitized, Analog-to-Digital Converter (ADC) must be able to treat the whole frequency band used by SRD, with a high enough resolution to properly demodulate the signals. This paper describes what the ADC's constraints are and how to dimension an ADC in SDR for SRD. An example based on the SmartSantander deployment shows that an ADC resolution of 21 bits is required to properly demodulate the data.","PeriodicalId":247495,"journal":{"name":"2014 IEEE Radio and Wireless Symposium (RWS)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127565729","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 work we analyze the energy detection characteristics over a generalized fading channel, modeled by the κ-μ distribution. Admitting the noise power estimation error, the worst-case of the probabilities of miss detection and false-alarm, due to the noise uncertainty, are derived under the spectrum utilization constraint. An optimal threshold selection is presented in order to allow the energy detector to operate in regions of low SNR. Field measurements are used to investigate in practice the usefulness of the κ-μ fading channel in cooperative spectrum sensing scenarios. Comparisons are performed against Rice fading model where it is possible to notice a great advantage in using the κ-μ distribution to describe the fading channel.","PeriodicalId":247495,"journal":{"name":"2014 IEEE Radio and Wireless Symposium (RWS)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129130662","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}
