In cooperative spectrum sensing, secondary users' observations are sent to a common receiver, the Fusion Centre (FC), to obtain a better understanding and decision about the state of the primary channel. This work, however, investigates how these observations of the secondary users can efficiently be exploited in such a way that minimises the collision ratio between the secondary and the primary users and at the same time maximises the exploitation of the unused frequency spectrum. As a result, a simple yet efficient approach is proposed for cooperative spectrum sensing, which, to the best of the authors' knowledge, has not been covered in the literature. This approach outperforms the conventional approach of cooperative spectrum sensing for reducing the interference and increasing the utilisation of the unused frequency spectrum in cognitive radio systems.","PeriodicalId":127186,"journal":{"name":"2021 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122684135","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 aim to maximize the energy-efficiency (EE) for an IRS-assisted downlink multiple-input single-output system. To solve the multi-variable non-convex optimization problem, a joint optimization of the transmit beamforming vector, power, and phase shift matrix at the IRS is performed with the help of the block coordinate descent (BCD) method. Presented simulation results demonstrate that the convergence of the BCD method is remarkably fast and the single iteration based solution has almost the same EE performance (less than 2.5%) as the iterative one. Meanwhile, the proposed scheme can achieve a 70.7% gain in EE when compared with the IRS-free counterpart.","PeriodicalId":127186,"journal":{"name":"2021 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126542630","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 developed learning scheme yields an online cross-layer scheduling policy which takes into account the randomness in packet arrivals and wireless channels, as well as the state of packet buffers. Inherent difference in the time-scales of packet arrival process and the wireless channel variations leads to sparsity in the observed reward signal. Since an RL agent learns by using the feedback obtained in terms of rewards for its actions, the sample complexity of RL approach increases exponentially due to resulting sparsity. Therefore, a basic RL based approach, e.g., double deep Q-network (DDQN) based RL, results in a policy with negligible performance gain over the state-of-the-art schemes, such as shortest processing time (SPT) based scheduling. In order to alleviate the sparse reward problem, we leverage prioritized experience replay (PER) and develop a DDQN-based learning scheme with PER. We observe through simulations that the policy learned using DDQN-PER approach results in a 3-5% lower PDP, compared to both the basic DDQN based RL and SPT scheme.","PeriodicalId":127186,"journal":{"name":"2021 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129879109","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 scheme generates a cryptographic key and aims to share it among the ATSoI’s participant entities securely. It mitigates several cyber-threats such as; DoS attack, replay attack, Man-In-The-Middle Attack, and eavesdropping activities with more potential occurrences in such cooperative systems. Moreover, it relies on a nonce instead of a timestamp to avoid time synchronization problems. Thus, it provides mutual authentication, confidentiality, message integrity, the privacy of the entities’ IDs, and checking the entities’ availability. A formal verification tool (ProVerif) is used to validate the proposed protocol’s security robustness through two main steps. Firstly, coding of the proposed protocol using ProVerif syntax. Secondly, performing the analysis of the attack trace for the failure queries.","PeriodicalId":127186,"journal":{"name":"2021 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129695652","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 idea of peer-to-peer energy trading is to export the surplus energy of a MG to a nearby MG or a group of MGs whose electrical load exceeds their generation. The variations in demand and generation, and the dynamic nature of these communities result in uncertainty on whether MGs will be able to satisfy their trading commitment or not. In this paper, the problem of energy trading among MGs is addressed with the objective of minimizing the cost under uncertainty. A Bayesian coalitional Game (BCG) based scheme is proposed, which helps the MGs to minimize the overall cost by forming stable coalitions. The results show 15% to 30% improvement in terms of cost minimization compared to an existing Q-learning based scheme and a conventional coalitional game theory (CG)-based approach from the literature.","PeriodicalId":127186,"journal":{"name":"2021 IEEE International Conference on Communications Workshops (ICC Workshops)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129546318","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 novel methods to dynamically and autonomously initiate new IAB-nodes in regions where UEs experience temporary quality of service degradation. Moreover, we propose methods for selective handover of UEs with low quality of service to new IAB-nodes in order to improve the overall performance of the system.
