In response to this problem, we consider to apply the cognitive radio technology in general, and the cognitive use of TV white space based on the white space database (WSDB) in particular, to the VANET where communication nodes (vehicles) move fast and for a long time. In order to provide stable and efficient communications over TV white space in VANET, (1) the quick acquisition of the status of license/primary users at the location and (2) the dynamic selection of an appropriate data channel are essential. To fulfill those two requirements, in this paper, we propose a database driven data channel selection scheme for VANET over TV white space. Through simulation experiments, we showed that the proposed scheme can reduce not only channel switching but also channel collision rate with a good balance, thereby improving the throughput performance as well.","PeriodicalId":115020,"journal":{"name":"2015 7th International Conference on New Technologies, Mobility and Security (NTMS)","volume":"09 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127364960","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, the interference from SM devices to digital television (DTV) system is a big problem when having an ambition of using this bandwidth as secondary users (SU). In addition, power allocation (PA) and channel selection (CS) are considered and discussed with many proposed approaches. In this paper, we propose the methods to prevent emission interference from SM system while achieving the best performance. In order to increasing the transmission performance, the optimization problems are defined with maximum channel capacity for transmission and minimum interference from SM system to DTV system. An assignment method called Hungarian algorithm (HA) is proposed to solve the channel assignment for SM system that warrants the fitness objective constraints.","PeriodicalId":115020,"journal":{"name":"2015 7th International Conference on New Technologies, Mobility and Security (NTMS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128740894","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}

On the basis of the bit-error-ratio (BER) bounds, joint power and rate adaptive QAM with network coding scheme is proposed for the purpose of improving the throughput of the relaying system. In addition, Network-coded-aided QAM suffers a modest SNR loss due to the direct current (DC) bias, which will be derived in detail in this paper.

The data rate for transmission varies from 100 bps to 3-4 kbps depending upon permissible error rate in different domains. The past techniques use only single voice channel from a sender to receiver and completely ignore the potential use of second voice channel from the receiver to sender. In this paper, we have examined the use of the second channel in data transmission that can significantly reduce the overhead of sending error codes in the forward channel during data transmission. We have also showed the use of this second channel as the feedback mechanism for adaptive data transmission that can adjust to the current error rate in transmission.","PeriodicalId":115020,"journal":{"name":"2015 7th International Conference on New Technologies, Mobility and Security (NTMS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130474684","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}

Not only in PMR networks, but the increase of proximity services due to the explosion of the internet of things bring us to a new communication paradigm. The PMR users have very specific requirements and one of those is the ability to communicate in a direct way with all the group members, even in out-of-coverage scenarios. In the current PMR standards, communication degradations due to collisions can occur when there is no infrastructure available, especially in dense scenarios. In this article, we propose a mechanism that allows device-to-device (D2D) broadcast communications, even in out-of-coverage scenarios. The mechanism presented hereafter improves the data rate compared to the current PMR mechanism, by reducing the number of collisions using the LTE physical resource block (RB) structure.","PeriodicalId":115020,"journal":{"name":"2015 7th International Conference on New Technologies, Mobility and Security (NTMS)","volume":"95 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133298431","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}

For that reason, it is necessary to develop standards designed specifically for vehicular networks aiming at the best use of their resources. In order to do this, the Wireless Access in Vehicular Environments (WAVE) was developed to enable wireless access in the vehicular environment. The WAVE architecture is based on a multi-channel operation, where only one channel is active at a given time and each channel is used for certain kind of applications. For this, a switching channel mechanism is required, but, due the use of only one antenna, this switching channel mechanism can introduce an undesirable effect that allows different vehicles to transmit simultaneously, resulting in collisions. Due to this, this paper presents an overview about the desynchronization problem and shows its impact in the VANET communication protocols.

In this paper we propose a joint transmission scheme for LTE-CoMP where MIMO precoding matrices at the transmission points are jointly (globally) selected to achieve higher capacity. The precoding matrices are jointly chosen by the User Equipment (UE) to fit the independent MIMO channels from two base stations (eNBs). In addition, edge users are likely to be subject to severe Co-channel interference from eNBs outside the joint transmission set. In order to address this issue, interference rejection combining (IRC) receiver is introduced to improve the cell-edge user performance. In this paper the performance of linear IRC receiver structures is investigated for interference suppression for CoMP-JT with local and global precoding matrix for closed loop spatial multiplexing MIMO. Simulation results show that the CoMP-JT with global precoding matrix scheme outperforms local precoding matrix with more than 1 dB. In addition, using MMSE-IRC gives much better performance than the conventional minimum mean square error (MMSE) in the presence of co-channel interference.","PeriodicalId":115020,"journal":{"name":"2015 7th International Conference on New Technologies, Mobility and Security (NTMS)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125438877","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}
