First, we choose a finite-length vector randomly, and we can construct circulant permutation matrices from the vectors. Then, the parity-check matrix can be produce from the circulant permutation matrices. Hence, the generators of stabilizer code are determined according to the parity-check matrix and quantum stabilizer group are defined from the generators. From the stabilizer group, codewords of the proposed quantum codes can also be generated. Finally, a complete efficient encoding and decoding quantum circuit of [[7,1,3]] is proposed. [[7,1,3]] is stabilizer code that construction based on our method is an seven-qubit code that protects a one-qubit state with up to one error, which is very important for quantum information processing.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123301167","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 paper investigates secondary user (SU) selection based cooperative spectrum sensing under exponentially embedded family (EEF) criterion. With an aim to estimate the optimal number of cooperative users who are better fitting for participating in cooperative sensing, we propose AIC, MDL, and EEF criteria to select the potential users among all cooperative users in the CR network. Based on the estimated user number, the global test statistic (GTS) is generated, and finally the fusion center (FC) makes the global decision on the presence/absence of the PU signal. Analysis and simulations verify that the proposed user selection based cooperative sensing schemes can significantly improve the spectrum sensing performance.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123328308","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}

However, due to side-lobe, blunt beam of main-lobe, fault adaptation, and so forth, a targeted signal can be leaked to a reactive jammer. By sensing the leaked signal power, the reactive jammer concentrates its own power to the frequency band of the targeted signal. To solve this problem, we suggest parallel transmission of the target signal and a decoy signal in addition to conventional joint tx-rx beamforming for anti-jamming. Because the decoy signal uses different frequency band from the target, jammer cannot help distributing its jamming power between these signals. By measuring signal-to-jamming-plus-noise power ratio (SJNR) and channel capacity under the high-performance reactive jammer, we show that the proposed anti-jamming beamforming scheme outperforms the conventional one especially in the presence of high power jamming.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129770866","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 propose an efficient uplink transmission scheme based on an orthogonal code division multiple access (OrCDMA) technique in a multiuser uplink transmission environment. While achieving minimal multiple user interference with the OrCDMA, the uplink performance is further enhanced with selection combining at the receiver, exploiting OrCDMA benefits. For bidirectional data transmission, we also employ time division duplexing (TDD). Performance evaluation was conducted for uplink transmission in an indoor VLC environment. It is found that with 5 uplink receivers installed, the bit-error rate (BER) is better than 10-5 over most locations and a BER of 10-5 is achieved at a signal-to-noise ratio (SNR) value of 5.5 dB for 16 users while maintaining a data rate of 58.18 Mbps.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134508485","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}

While it has the feature of asynchrony and power-saving, the interference power increases as the number of nodes increases. In a prior study, Intermittent Receiver-Driven data Transmission (IRDT) MAC has been proposed with finding the appropriate transmission cycle and the communication performance is improved by the derivation of the collision probability. In this paper, we introduce a collision probability analysis of IRDT-MAC to U-Bus Air. However there is a problem that it cannot correspond to a change of link topology. We propose a protocol for controlling receiver beacon transmission interval by the Fusion Center (FC). In this protocol, the link topology of each smart meter is sent to the FC and the FC calculates the suitable transmission cycle from this individual topology. Finally, this suitable transmission cycle is fed back to each node from the FC. By using the computer simulations, the improvement of packet delivery ratio (PDR), the throughput and the reduction of power consumption are confirmed.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131025538","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}

Specially, WLAN-based vehicular Internet access can be a complementary and cost-effective solution considering the cost of cellular service. For WLAN-based Internet connected vehicles, we propose an efficient load-aware association mechanism which allocates vehicles to roadside APs properly, and eliminates the unnecessary steps during scanning phase. We defined the load condition as a set of parameters, relative priority of parameters, and determined decision weights in order to select one AP for each vehicle. We evaluated the performance of the proposed mechanism, comparing with the strongest-RSSI-first selection for AP. Depending on the traffic volume, the proposed mechanism showed better performance in the average throughput ratio by about 20%.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131112492","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 concurrent requests bring about the congestion of the channel. To solve the problem, 3GPP has adopted overload resolution mechanisms like ACB (Access Class Barring) and EAB (Extended Access Barring). In the mechanisms, barring parameters need to be set dynamically to reshape the access intensity of MTC devices. This paper proposes how to determine a barring parameter in ACB mechanism adaptively as an overload resolution mechanism. The experimental results show that our mechanism improves system performances including access success probability, collision probability, and access delay.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133800076","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 in-taxi video advertising systems, each advertisement is characterized by a specified play count requirement and its contract period. The system should finish playing the contractual advertisements by the end of their contract periods to meet play count requirements. However, since the limited carrying time provided by all operating taxis is shared among multiple advertisements, unfair assignment of play counts may happen if we play advertisements in an inappropriate order during carrying services: Some advertisements may be allocated a considerable number of play counts at the cost of narrowing others. In this paper, we apply the concept of utility function to represent the level of satisfaction of an advertiser for various advertisements, and propose an algorithm to schedule the display order of advertisements with fairness concern such that the total utility is maximized. We conduct a series of experiments to emulate the operations of the system in the real world with real data. The results show that our proposed scheme has significant superiority in terms of total utility and fairness for all advertisements in the system.","PeriodicalId":403815,"journal":{"name":"2016 Eighth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133330179","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 proposed service uses temporal relationship between device usage statistic data to create interaction services. To gather device usage statistic data, the proposed service employs IoT Delegate which works as a proxy for IoT services, and temporal relationship is computed using cross correlation between statistic data.
