However, the search for the feasible Parity-Check Idempotent runs through all possible combinations of cyclotomic cosets modulo n, satisfying some algebraic constraints, consequently, increasing the code length may result in very large dimension space search, and the search for the solution becomes more difficult. In this paper, we propose a Genetic Algorithm that aimes to construct new moderate and high lengths Binary Cyclic OSMLD codes, considered as LDPC codes, with high correction capacities. Our construction is very efficient and provide codes with high lenghts and high rates.","PeriodicalId":389513,"journal":{"name":"2015 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115496338","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 introduces an overview of the concept, performance evaluation gains and our experimental trials related to NOMA. The goal is to clarify the benefits of NOMA over orthogonal multiple access (OMA) such as OFDMA adopted by Long-Term Evolution (LTE), also its combination with MIMO is discussed. Using computer simulations, NOMA performance gains are assessed from both link-level and system-level perspectives. Also, our NOMA test-bed and the measurement results are explained. Our evaluation results and measurements show that NOMA provides higher gains compared to OFDMA. These gains are more than 30%.","PeriodicalId":389513,"journal":{"name":"2015 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128617700","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 basic idea is that a primary user (PU) transmits his traffic assisted by some selected secondary users (SUs), which transmit also their own traffics using the same channel. The existing works in the literature propose the use of the same channel by applying a time division approach, where a time slot is dedicated to secondary traffic transmission, which degrads system performance. To overcome this problem, the use of multiple antennas enables simultaneous primary and secondary transmissions. Furthermore, the integration of beam-forming techniques removes the interference generated by this simultaneous transmissions. However, for almost systems proposed so far, only the PU and one SU can transmit simultaneously. In this paper, we propose a new scheme of CCRN where SUs communicate with a fusion center (FC) over a TV White Space (TVWS) band and perform a modulation matrix that allows simultaneous transmissions of the PU and all SUs with no interferences. Finally, we prove by theoretical studies and simulations that the suggested model improves significantly the rate of secondary users yet retaining good performances for the primary link.","PeriodicalId":389513,"journal":{"name":"2015 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"247 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127391993","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}

Because of their enormous benefits, the use of this type of wireless networks is surprisingly increasing day by day and it has a strong presence in several domains. However, WBAN has many challenges yet to be resolved. Security is the most crucial issue. In this paper, we propose a novel key agreement scheme termed Physiological-Feature-based Key Agreement (PFKA) as a biometric based security system. The proposed scheme allows sensors belonging the same WBAN to agree on a symmetric cryptographic key generated from overlapping physiological signal features. On one hand, security analysis shows that our protocol can guarantee data confidentiality, authenticity and integrity. In the other hand, performance analysis show that our scheme reduces communication overhead in comparison with the other proposal protocol termed Secure and Efficient Ordered-Physiological-Feature-based Key Agreement for Wireless Body Area Networks (OPFKA).","PeriodicalId":389513,"journal":{"name":"2015 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125679636","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, in order to study and analyze Jitter, many works and models have been devoted to estimate and evaluate this parameter. In this paper, analytical formulas for jitter of interrupted Poisson traffic (IPP) and MMPP-2 are presented. We provide Jitter approximation for The IPP Model. Moreover, we found that the jitter calculated directly using the IPP process is almost equal to that found by the EPP model. We have found that jitter can be a decreasing function of load. Simulation results show that the delay and jitter behave inversely which confirms the result already found in [8]. Finally, we found value of the average arrival rate and service rate required to provide flexible and efficient QoS guarantees for VoIP.","PeriodicalId":389513,"journal":{"name":"2015 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131633331","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}

Yet, the allocation of powers to base stations should be optimal in order to minimize interferences and thus improve users through-put. In this paper, we present a game theoretical approach to maximize the overall throughput in heterogeneous networks with optimal power allocation. We formulate the allocation problem as a \"potential game\". This type of games is characterized by a potential function, and has a specific property: a pure Nash equilibrium solution always exists and it is, moreover, either a local or a global optimizer of the potential function. We use a fully distributed algorithm that requires minimal coordination between base stations to reach a Nash equilibrium, and we prove that it is necessarily a global maximum. The performance of the algorithm is evaluated through simulations.","PeriodicalId":389513,"journal":{"name":"2015 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128547818","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 traditional techniques for error control are FEC (Forward Error Correction) and ARQ (Automatic Repeat Request). In this paper a hybrid FEC/ARQ mechanisms with limiting the slots number between the loss of the last retransmission of the original block n and the reception of block n + φ is analyzed in an environment of real time applications. We assume that the packet size increases when adding redundancy so that the amount of useful information contained in a packet is unchanged. We evalute analytically the performance of TFRC (TCP Friendly Rate Control) and ARC (Analytical Rate Control Protocol) as a function of the parameters of the FEC scheme, the limit number of retransmission used by ARQ scheme and the number of slots threshold Sth. We show that the combination of FEC and ARQ with limiting the Sth reduces the number of retransmissions and keeps a reasonable delay for real time traffic in wireless networks.","PeriodicalId":389513,"journal":{"name":"2015 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128577250","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 antenna is excited by using the edge, inset, probe and aperture feeding methods. Genetic Algorithm optimization technique has been utilized for the optimization of patch antenna dimensions. The double layer dielectric superstrate disposed above the patch antennas are used for enhancing the directivity and also for getting better return loss since microstrip antennas have limitations in directivity, gain and efficiency. The proposed antennas are simulated by using the Ansoft High Frequency Structure Simulator software. The characteristics of the edge, inset, probe and aperture feeding patch antennas covered by superstrate are obtained in terms of return loss, directivity, voltage standing wave ratio and radiation pattern and are compared with those of the same patch antennas without superstrate. We also carry out a parametric study of the distance between the lower and the higher superstrate, and examine how this separation distance affects the directivity and beam shaping of the composite structure. The return loss up to -47.06 dB and directivity equal to 13.5 dB are obtained at the center frequency of 8 GHz for the aperture coupled patch antenna through the use of the superstrate layers. This antenna is found to be suitable for X band applications.","PeriodicalId":389513,"journal":{"name":"2015 International Conference on Wireless Networks and Mobile Communications (WINCOM)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128831814","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}
