Near Field Communication (NFC) mobile payment is gaining popularity and it is widely considered to be the technology that will turn smartphones into m-wallets. While a typical wallet contains identification, loyalty, public transport and credit cards, m-wallet solutions currently have well-defined standards for credit card enrollment and usage only. In this thesis, we explore and present the main reason for this limitation. Then, we introduce a new method for using the Secure Element (SE) inside the NFC Phones which allows standard enrollment and usage for proprietary payment and identification schemes. We also explain the practical use our model by presenting well-known proprietary payment scenarios such as public transport payment. This study makes significant contributions to NFC technology by proposing a method for proprietary transaction flows that can be used in parallel with NFC credit card payment solutions. Furthermore, it provides an open protocol which can serve as an NFC payment and identification transaction execution standard.","PeriodicalId":187747,"journal":{"name":"2016 IEEE 17th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122637510","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 paper, we study the feasibility and accuracy of VEH for detecting hotwords, such as “OK Google”, used by popular voice control applications to distinguish user commands from other conversations. The idea of using power signals of VEH to detect hotwords is based on the fact that human voice creates vibrations in the air, which could be potentially picked up by the VEH hardware inside a mobile device. Using off-the-shelf VEH product, we conduct a comprehensive experimental study involving 8 subjects. We analyse two possible usage scenarios for the VEH hardware. In the first scenario, the user is not required to talk directly to the device (indirect), but the VEH is expected to pick up the ambient vibrations caused by user-generated sound waves. In the second, the user is expected to direct his voice to the VEH (direct) and talk to it from a close distance. For both usage scenarios, we evaluate two types of hotword detection, speaker-independent and speaker-dependent. We find that VEH can detect hotwords more accurately in the direct scenario compared to the indirect. For the direct scenario, our results show that a simple Decision Tree classifier can detect hotwords from VEH signals with accuracies of 73% and 85%, respectively, for speaker-independent and speaker-dependent detections. Finally, we show that these accuracies are comparable to what could be achieved with an accelerometer sampled at 200 Hz.","PeriodicalId":187747,"journal":{"name":"2016 IEEE 17th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132797272","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}

With limited codebook size, how to design the steering angles to compensate angles of arrival and departure (AoAs/AoDs) is essential to beamforming performance. Typically, two categories of steering vector sets are commonly used. One is orthogonal steering vector set where the spatial frequency indices of the steering angles are uniformly distributed in spatial frequency domain. The other one is non-orthogonal steering vector set where the steering angles are uniformly distributed in angle domain. In this paper, analyses of these two designs are presented. Due to the fact that beamwidth are constant with respect to different spatial frequency indices in spatial frequency domain, if the spatial frequency indices are uniformly distributed, one has the smallest deviation of the beamforming gain. Since the orthogonal steering vectors satisfy this condition that spatial frequency indices are uniformly distributed, they can achieve higher data rates than the non-orthogonal ones when the AoAs are uniformly distributed over (-π/2, π/2).","PeriodicalId":187747,"journal":{"name":"2016 IEEE 17th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"541 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133523749","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}

This explosive growth has contributed to an unprecedented adoption of mobile data services and increase in data usage. The demand is also driving the development of next generation networks to support novel data hungry and user-experience focused applications such as virtual reality video. Global mobile data traffic is increasing at an unprecedented rate and video traffic alone currently constitutes about 50% of the total traffic and is predicted to grow up to 70% by 2021 as user preferences are shifting towards more video based applications relative to browsing. The explosion of traffic associated with video content poses significant challenges for mobile content provision. While, on the one hand, mobile video traffic surge is forecasted to require significant investments in bandwidth acquisition, infrastructure deployment and roll-out, on the other hand, users are not likely to be willing to pay significantly more than they are today. Operators would in turn like to charge the content providers for revenue. Furthermore, user expectations for high quality video content is constantly increasing.","PeriodicalId":187747,"journal":{"name":"2016 IEEE 17th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"116 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131486926","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}

Recently, the Enhanced Jump-Stay (EJS) scheme [13] has been proposed that decreases the Maximum Time To Rendezvous (MTTR) and the Expected Time To Rendezvous (ETTR) for users with a different number of channels (asymmetric). We develop a Symmetric Channel Detecting Jamming (SCDJ) attack and a novel probabilistic Asymmetric Channel Detecting Jamming (ACDJ) attack that dramatically decrease the rendezvous success rates of EJS. Our simulation results show that ACDJ significantly reduces the rendezvous probability of the asymmetric EJS scheme. We analyze the Random rendezvous scheme for the asymmetric model and show it vastly outperforms asymmetric EJS under ACDJ. We also developed the Random Enhanced Jump Stay (REJS) rendezvous that guarantees MTTR, significantly decreases the Expected Time To Rendezvous (ETTR) of EJS, and, due to the random part, appears to be resistant to channel detecting jamming attacks. REJS appears to be uniformly better than EJS with major performance improvements and significantly smaller theoretical ETTR upper-bounds and similar positive simulation results.","PeriodicalId":187747,"journal":{"name":"2016 IEEE 17th International Symposium on A World of Wireless, Mobile and Multimedia Networks (WoWMoM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133601008","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}
