The RIS requires low power in reflecting the impinging base station (BS) signals towards the direction of the user equipment (UE), and the cooperative transmission can provide a more stable connection that guarantees quality-of-service (QoS). In this work, we investigate the energy efficiency (EE) maximization of a multiple-BS single-UE single-aerial-RIS setup and the usefulness of cooperation to prevent outages. The BSs can be turned either on or off depending on their contribution to the EE, and the system is subject to QoS, power, capacity, and RIS specific constraints. We formulate a problem that jointly optimizes the selection of the BSs and the beamforming weights of BSs and RIS, and solve it with a Branch-Reduce-and-Bound (BRnB) algorithm that uses monotonic optimization and semidefinite relaxation steps. Simulation results for an illustrative setup show that the aerial-RIS increases the EE by 50% when doubling the number of its elements and cooperative aerial-RIS transmissions help to solve outages of single-BS cases.","PeriodicalId":6802,"journal":{"name":"2021 IEEE Globecom Workshops (GC Wkshps)","volume":"7 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72708262","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}

It has fueled intensive research into the design and development of post-quantum (PQ) cryptographic systems that maintain their security when a quantum computer is built.We consider the PQ security of DTLS (Datagram Transport Layer Security), a communication security protocol that protects against eavesdropping, tampering, and packet forgery for datagrams. DTLS is the UDP counterpart of TLS (Transport Layer Security) and proposed to secure control messages in 5G networks. We offer a novel and efficient approach for providing secure source authentication and message integrity for DTLS that removes the need for a computationally expensive key exchange for message integrity by using PQ TESLA (Timed Efficient Stream Loss-tolerant Authentication) that relies on delayed key release mechanism to provide integrity and use a PQ hash-based signature for providing PQ source authentication. We analyze the security of our design, implement it in a widely used library called TinyDTLS, report the result of our experiments, and propose direction for future research.","PeriodicalId":6802,"journal":{"name":"2021 IEEE Globecom Workshops (GC Wkshps)","volume":"114 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75677930","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}

A major novelty of the proposed framework is that it introduces the new paradigm of flexibility on efficient spectrum sharing between aerial and ground cellular users by taking advantage of the aerial users’ high mobility, reconfigurable wireless environment as well as power-domain multi-user access. With the aim of maximizing network sum rate while guaranteeing users’ quality-of-service (QoS) requirements, a joint problem of unmanned aerial vehicle (UAV) trajectory and RIS configuration design is formulated. The formulated problem is a sequential decision making one across multiple coherent time slots. Moreover, considering ground users’ random movement in practice, the decision making process involves uncertainties. To solve the formulated problem efficiently, the deep reinforcement learning algorithm is adopted to intelligently adjust the UAV’s trajectory and RIS configuration simultaneously. Numerical results demonstrate that the network sum rate is significantly improved with the proposed NOMARIS scheme compared to conventional orthogonal multiple access (OMA) communication and the case where no RIS is deployed.","PeriodicalId":6802,"journal":{"name":"2021 IEEE Globecom Workshops (GC Wkshps)","volume":"87 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78980839","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 false alarm leads to throughput loss of the secondary network whereas mis-detection causes interference to the primary network. Another issue with CR environments is that the primary user (PU) activity may change at any moment during the transmission of secondary user (SU) which may cause interference (excluding the interference due to mis-detection). All the aforementioned problems can be addressed if the SU exactly knows the PU’s activity. In this paper, a novel transmission protocol for a multi-antenna SU is proposed to implement smart sensing, where the PU helps SU in obtaining its activity status. Here, the SU gets the exact information of PU’s activity without performing spectrum sensing, therefore, it is expected that the proposed transmission protocol can achieve more throughput since the sensing time overhead and throughput loss due to SU’s false alarm are saved at the cost of paying back to PU for its activity information sharing. Thus, the proposed protocol helps in realizing a smart sensing CR environment by saving the losses that occur due to spectrum sensing. In this work, we have analyzed the performance of the proposed transmission protocol in terms of SU’s average throughput and derived the tight closed-form approximation. Lastly, numerical results validate the analysis and provide insights on the performance gain of our proposed transmission protocol.","PeriodicalId":6802,"journal":{"name":"2021 IEEE Globecom Workshops (GC Wkshps)","volume":"1 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75991463","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}
