In a CR network, a secondary base station (BS) serves a couple of users, i.e., near and far users, via NOMA transmission under eavesdropping from a malicious attacker. It is assumed that the direct transmission link from the BS and far user is absent due to obstacles. Thus, an IRS is utilized to support far user communication, however, the communication links between the IRS and near/primary users are neglected because of heavy attenuation. The exact secrecy outage probability (SOP) for the near user and approximate SOP for the far user are then derived in closed-form by using the Gauss-Chebyshev approach. The accuracy of the derived analytical SOP is then verified through Monte Carlo simulations. The simulation results also provide useful insights on the impacts of the number of IRS reflecting elements and limited interference temperature on the system SOP.","PeriodicalId":388547,"journal":{"name":"2022 IEEE Ninth International Conference on Communications and Electronics (ICCE)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130260236","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 low complexity algorithm is efficient and applicable for both Legacy and recent Wi-Fi devices which are based on IEEE 802.11n/ac/ax/be standards. The algorithm maintains for each station a statistic of the Packet-Error-Rate of its feasible transmission rates considering its actual received signal strength indicator available at the access point. For each station, the algorithm then deduces the achievable throughput of these feasible transmission rates and selects the best one which results in the highest achievable throughput. We simulated this algorithm in MATLAB as well as implemented it in a Wi-Fi access point which is based on Qualcomm chip-set. We measured the performance of this device in laboratory and real Over-The-Air environments. The simulation and measurement results confirmed that the rate quickly converges to the optimal value when the channel condition suddenly changes. In addition, this algorithm helps in improving the achievable throughput of the applied device by 15% without any hardware upgrade.","PeriodicalId":388547,"journal":{"name":"2022 IEEE Ninth International Conference on Communications and Electronics (ICCE)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127856148","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 a joint optimization of user pairing strategy with beamforming and power allocation to maximize the minimum downlink rate per user. To solve the problem, we first relax the binary variables to continuous variables, and then we develop an iterative algorithm based on the inner approximation method. Numerical results show that the proposed user pairing algorithm outperforms the existing counterparts, such as beamforming, random pairing, far pairing, and close pairing strategies.","PeriodicalId":388547,"journal":{"name":"2022 IEEE Ninth International Conference on Communications and Electronics (ICCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122579310","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}

To provide the transmissions from the BS to UEs, we propose to adopt UAVs as aerial relays, given that massive MIMO, a mainstream technology for the next generation network, is assumed to be deployed at the BS. In this work, we provide a novel analytical analysis of the proposed UAV relay mMIMO system focusing on the spectral efficiency. Furthermore, the system sum rate maximization problem is also formulated by jointly optimizing the altitude of the UAV and the quality-of-service (QoS) conditions of ground UEs. The problem is naturally hard to solve due to the non-convex constraints and non-concave objective function. To address it, we propose a two-step algorithm based on inner convex approximation. Then numerical results are used to demonstrate the validity of the theoretical analysis and the effectiveness of the proposed approach.","PeriodicalId":388547,"journal":{"name":"2022 IEEE Ninth International Conference on Communications and Electronics (ICCE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125394451","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}

As the Internet of Things (IoT) includes a considerable number of devices, their efficient management is essential. It is also crucial to leverage frameworks to handle the heterogeneous IoT resources, regardless of their technology, to be part of a single ecosystem. FIWARE, a widely used IoT middleware, offers a set of services to tackle such heterogeneity in IoT. Among them, we have Ultralight and Lightweight Machine-to-Machine (LwM2M) IoT agents. However, which one of both should we choose under a given situation? In this paper, we present the results of their comparative assessment in both mobile and stationary scenarios. The study targeted packet loss, delivery delay, and bandwidth occupancy widely adopted metrics in networking. We show that network conditions may have a substantial impact on the performance of any of the services.

Furthermore, we perform extensive computer simulation works to discover that the equal-weight superposition constellation is the best choice in the coded system as the system can enjoy the power gain of the constellation and exploit the error-correcting power of the protograph low-density parity-check codes (LDPC) previously designed for LS-MIMO channels.
