To improve the user's quality of service (QoS) in that systems, in the present study, we propose a user cooperation aided clustering approach based on device-centric architectures and enable the multi-user multiple-input multiple-output transmissions with non-reciprocal setups. We actively use device-to-device communication techniques to achieve the sharing of user information and try to form clusters on user side instead of the traditional way that performs clustering on base station (BS) side in data offloading. We further adopt a device-centric architecture to break the limits of the classical BS-centric cellular structure. Moreover, we derive an approximate expression to calculate the user rate for LS-DASs with employment of the zero-forcing precoding and consideration of inter-cluster interference. Simulated and numerical results indicate that the approximate expression predicts the user rate with a lower computational cost, and the proposed approach provides better user experience for, in particular, the users who have unacceptable QoS.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131528729","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}

SDN brings great flexibility and openness to the network, but the original design phase of SDN had not considered designing characteristics regarding security. For this reason, there are many potential vulnerabilities in SDN Environments. One of the most critical security threats arise from the vulnerability of trusting relationship due to the lack of authentication mechanism between the network application and the controller. A specific concern is whether an application can be trusted or not. This paper discusses the authentication mechanism of the network application. At the same time, it implements the application authentication system which addresses the key challenges: how to safely resolve conflicts between untrusted network applications and requests. The paper undergoes system testing in testbed constructed Floodlight architecture. The test results show that the system works well to effectively defend against unauthorized access and provide log history, which verifies the effectiveness of the proposed method to secure the northbound interface by introducing the application authentication system.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133979511","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}

Multiple-input multiple-output (MIMO) has been widely implemented or standardized to improve the throughput performance of wireless communications. Forward error correction (FEC) codes are also key techniques for stably improving bit error rate (BER) and have been studied as well as a demodulation scheme. FEC is required to be composed of simple encoder and decoder while achieving good BER performance as much as possible. Polar codes emerged as a promising FEC scheme. This code has a simple recursive encoder structure by using a phenomenon called \"channel polarization\". In addition, it has been reported that polar codes provably achieve the theoretical limit for communication systems with a successive cancellation decoder based on likelihood ratio. An calculation complexity of polar codes is less than that of low density parity check (LDPC) codes. Therefore, polar codes are an effective technique in realizing low electric power consumption to meet one of the demand conditions of 5G. Based on legacy detection schemes as zero forcing (ZF) and maximum likelihood detection (MLD), computer simulation results reveal the fundamental BER performance with controlling coding rate. Moreover, there is a problem that the log likelihood ratio (LLR) of MLD detection for soft-decision decoding can not be obtained. Therefore, in this paper, we investigate the likelihood function of MLD detection in the proposed system.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"1 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120927967","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}

Hyper-exponential distributions of different orders (i.e., number of phases) are considered. Both moment matching and expectation maximization algorithm are employed and evaluated to determine the parameters of the hyper-exponential distributions that provides the best fit to the corresponding log-normal ones. A general teletraffic analysis is developed for the performance evaluation of the CRN considering an arbitrary order of the hyper-exponential distribution. The performance of the CRN is evaluated in terms of the new call blocking and forced termination probabilities of secondary users. Numerical results are obtained for both different ratios (acceleration factor) of the mean service times of PUs and SUs and different values of the number of phases of the hyper-exponential distribution. Numerical results show that, except for small values of the acceleration factor, the values of the different performance metrics obtained considering an n-th order hyper-exponential distribution become closer to those obtained by discrete event computer simulation (where the log-normal distribution is used to model the secondary service time) as n increases. For small values of the acceleration factor, the different performance metrics are insensitive to the probability distribution beyond the mean of the secondary service time.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121028130","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}

According to many stakeholders, the adoption of software defined networking (SDN) principles in 5G (5-th Generation) wireless networks will allow the integration of mobile networks and the internet of things and will make it possible to manage billions of connected smart objects through intelligent orchestration and provisioning systems. The special value of SDN lies its ability to support network virtualization and to automate deployment of new services on top of the virtualized network infrastructure. To pave the way towards this novel approach, we present a SDN-based architecture for virtualization of IoT networks, including an intent-based north-bound interface and a virtualized infrastructure manager, allowing virtualization of IoT resources. The architecture exploits SDN controller to program different IoT networks in order to provide to users the intended service at the requested level of quality. A prototype of the architecture is presented and numerical results related to round trip time, measured at the different levels of the architecture, are reported.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115980364","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}

Since the perfect channel state information (CSI) is difficult to obtain in practice, we consider the CSI errors follow a complex Gaussian distribution in this paper. We aim to minimize the average total transmit power at the cognitive base station (CBS) subject to the probabilistic signal-to-interference-plus-noise ratio (SINR) and energy harvesting (EH) constraints at each secondary user (SU) and probabilistic interference temperature constraint at primary receiver (PR), respectively. As the probabilistic constraints have no closed-form expression, the original optimization problem is difficult to be solved. As a solution, the probabilistic approach based on two kinds of Bernstein-type inequalities is proposed to reformulate the original non-convex problem to the form of semi-definite programming (SDP) after rank-one relaxation. We also propose the worst-case approach based on S-Procedure to solve the original problem. Simulation results are performed to demonstrate that the proposed RBFPS based on both probabilistic approach and the worst-case approach are robust to the CSI errors. In addition, the probabilistic approach is less conservative and more energy-saving.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128382900","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}
