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.

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.

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}

Using substrate-integration technology, the antennas will be fabricated onto substrate to reduce cost, size, transmission loss, and enhance integration into circuits. This talk will brief the design challenges in mmW antenna design and substrate-integration technology first. After that, recently developed substrate-integrated high-gain antenna arrays for 60-270 GHz applications are exemplified with the introduction of the latest built measurement system up to 325 GHz.

However, most dominant 2D touch sensing technologies are based on a grid of connections and sensors, which are thick and cumbersome. Thus flexibility and form factor do matter. In this paper, we propose an algorithm to design a flexible two-dimensional touch-sensitive surface using inkjet printing technology. Due to its flexibility and conformability, it is possible to turn everyday objects and surfaces into touch sensors. Different from existing touch sensing technologies like resistive based and capacitive based sensing method, we detect touch motion using Time-domain Reflectometery (TDR), which is originally used to locate faulty in electric cable. An existing work on TDR based touch sensing method suggested implementing Hilbert space-filling curves' pattern to improve sensing accuracy in all directions. But pure Hilbert curves are restricted to only square shape with size of 2n unit length. In this paper, we tackled this problem by introducing an algorithm to automatically generate appropriate quasi-Hilbert Space-filling Curve (SFC) for any shape of surface. Our algorithm could fill any arbitrary surface with high coverage curve while retain advantages of Hilbert SFCs. We also utilize conductive inkjet printing with silver nanoparticle ink to rapidly prototype thin and flexible surfaces on paper substrate.","PeriodicalId":247495,"journal":{"name":"2014 IEEE Radio and Wireless Symposium (RWS)","volume":"81 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":"126437824","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}
