Previous studies already provided models, algorithms, and proofs of concept to exploit the radio physical layer and generate symmetric keys over single links. Some of these models have been adapted to cooperative scenarios involving several nodes, either to reinforce the generated pair-wise keys or to issue a common group key (i.e., shared by more than two nodes). In this study, we focus on key agreement from Impulse Radio - Ultra Wideband (IR-UWB) multipath channels according to the source model. We propose a new method to generate group keys within cooperative scenarios, while exploiting all the available physical links in a full mesh topology and reducing over-the-air traffic. The main idea consists in adjusting the IR-UWB signals usually transmitted for channel probing so that receiving nodes have access to non-observable channels corresponding to their non-adjacent links. We describe an example where the transmitted signal is optimized using a least squares minimization routine with prior information.","PeriodicalId":339208,"journal":{"name":"2015 IEEE International Conference on Ubiquitous Wireless Broadband (ICUWB)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114757055","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 problem a relay node needs to deliver a set of packets to a set of client over a broadcast wireless channel. Each client might posses some \"side information\" related to the transmissions by the relay node. The goal is to minimize number of transmissions from the relay node by taking advantage of the side information. The Index Coding problem has been proven to be NP-hard and NP-hard to approximate. The Complementary Index Coding problem is a complementary problem of the Index Coding problem. In the Complementary Index Coding problem the objective is to maximize number of the saved transmissions, i.e., the number of transmissions that are saved by encoding packets compared to the solution that does not perform coding. This work aims at improving the gains of the Complementary Index Coding problem by proposing a Set Cover based solution that guarantees an approximation ratio of 1/(1-(H_k|S|/n)). Moreover, we propose a scheme for transforming the Index Coding problem in to the Set Cover problem. In addition to this, we compare the proposed algorithm with the current state of the art. The experimental results show that the proposed solution out performs current state of the art both in terms of coding advantage as well as running time.","PeriodicalId":339208,"journal":{"name":"2015 IEEE International Conference on Ubiquitous Wireless Broadband (ICUWB)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128071320","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 new CRBs of the angular parameters are compared to those obtained from circular ID signals. The CRB of the central DOAs, however, are compared to those obtained from both circular and noncircular point sources. It will be shown that the CRB of both the central DOAs and the angular spreads obtained assuming noncircular ID sources are lower than those obtained using circular ID sources. This illustrates the potential gain that the noncircularity characteristic of the sources provides for the estimation of the angular parameters, especially in presence of different sources' distributions and for high angular spreads. Finally, the CRBs derived assuming noncircular ID signals decrease as the noncircularity rate increases. Furthermore, this decrease is more prominent at low DOA separations where the CRBs are sensitive to the noncircularity phase separation.","PeriodicalId":339208,"journal":{"name":"2015 IEEE International Conference on Ubiquitous Wireless Broadband (ICUWB)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122704317","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 transceiver offers exceptionally low power consumption while providing a high data rate using injection-locked oscillator. The transceiver utilizes Frequency- Shift-Keying (FSK) modulation at a data rate of 8 Mbit/s to provide wireless link between target implantable device and a central base-station unit operating in the North American Industrial, Scientific and Medical (ISM) frequency band. The circuit features a fully passive wake-up receiver (WuRx) enabling energy harvesting from Radio Frequency (RF) input. The amplitude of the FSK RF signal is controlled low for short distance transmission to further reduce the energy consumption. The transceiver, implemented in 0.13 μm CMOS process, is built on new FSK modulation scheme and based on frequency to amplitude conversion. The WuRx achieves a sensitivity of -53 dBm while the main receiver shows -78 dBm sensitivity. Thanks to the simplified hardware, the receiver dissipates only 640 μW while the transmitter consumes 1.4 mW from 1.2 V supply voltage.","PeriodicalId":339208,"journal":{"name":"2015 IEEE International Conference on Ubiquitous Wireless Broadband (ICUWB)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122713158","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}
