Unmanned aerial vehicle (UAV) has attracted a lot of attention due to the high mobility. However, both machine-type communications devices (MTCDs) and UAVs are battery-powered, therefore they have limited energy storage. In this paper, we focus on energy efficiency optimization in UAV-assisted mMTC networks with altitude differences. Considering the altitude differences of MTCDs, the Euclidean distances between MTCDs are in three dimensions. Besides, the altitudes of clustering centers are different, which results in the different altitudes of the hovering positions. To optimize the energy efficiency of MTCDs, a hovering positions selection algorithm based on three-dimensional clustering (3D-HPSA) is proposed. Meanwhile, a Discrete Cuckoo Search Algorithm with Genetic Mutation Operators (GMO-DCSA) is proposed to optimize the flight distance and the energy efficiency of UAV. Simulation results show that the proposed algorithms have superior performances compared with the existing works.","PeriodicalId":425118,"journal":{"name":"2021 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121170266","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 solve the problem, a bionic covert UAC scheme based on dolphin whistle with time-delay, abbreviated as BCUAC-TD, is proposed in this paper. In the proposed BCUAC-TD scheme, we divide the time-frequency structure (TFS) into several segments uniformly to represent different symbol signals, and the time-delay is used to carry different information. Moreover, the energy compensation and the virtual time reversal mirror (VTRM) are adopted to improve the performance the demodulation.

This article proposes a dynamic power allocation method for the inter-satellite link of Low Earth Orbit (LEO)/Medium Earth Orbit (MEO) satellites based on the computing power of LEO satellites. A utility function is designed according to the transmission characteristic of the inter-satellite link. The existence of the Nash Equilibrium (NE) of the utility function is proved based on the super-modular game theory. The LEO satellite obtains its balanced solution of the transmission power through the Newton iteration method. In this process, based on the initial orbit parameters of the satellite and the satellite operating time, the inter-satellite link distance is predicted through the spherical geometric relationship between the LEO/MEO satellites, so that the signal-to-interference and noise ratio (SINR) can be estimated in advance. The MEO satellite controls the penalty factor to enhance the utility of the entire network. Simulation results show that the proposed power allocation method achieves the purpose of saving power resources while improving system performance.","PeriodicalId":425118,"journal":{"name":"2021 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116121188","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 focus on the formal specification and security verification of 5G AKA. We propose three attack methods including: Sequence Number (SQN) mismatch attack, Subscription Concealed Identifier (SUCI) replay attack and bogus serving network (SN) attack based on the most general assumptions on entities. For the three attacks occurred in wireless channel and SN, we also give an improved scheme by adopting challenge response mechanism and designing Unique Identifier (UNI) for the AKA protocol. The former is used to prevent an attacker with a fake SN interfering the authentication process, while the latter ensures the security of messages in wireless channel. With the advantages such as graphical nature, the simplicity of modeling and the firm mathematical foundation, Petri net is applied for the attack-driven modeling. To the best of our knowledge, this is the first time that Petri net has been introduced to validate security scheme for 5G AKA protocol in the literature.","PeriodicalId":425118,"journal":{"name":"2021 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116175100","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, the local model uploading causes information leakage on local data. Differential privacy (DP) is a random mechanism that adds uncertainty to protect privacy for dataset. In this paper, we study a multi-cell FL network where each cell is a FL system. Each user adds artificial noise in its uploaded local gradient, and the multi-cell interference is exploited to enhance the DP levels. The studied problem is formulated as a mean square error (MSE) minimization problem subject to the DP and power constraints, by controlling the transmission power on local gradient and artificial noise of each user.

To deal with the complex co-channel interference resulting from the dense spectral reuse, we aim to maximize the sum proportional bit rate by jointly optimizing mode selection (MS) and power allocation (PA). Considering the high complexity of the original problem and the dynamics of the wireless environment, we propose an online mechanism with a double-layer structure by efficiently combining machine learning with optimization theory. In particular, when the MS scheme is given, the remaining nonconvex PA problem can be equivalently transformed into a convex one under certain manipulations. Based on the above optimum, a deep reinforcement learning-based online mechanism is designed and it constantly refines the output MS scheme generated from a deep neural network by utilizing the recent historical experiences via reinforcement learning. Finally, simulations are conducted to validate the superiority of the proposed mechanism in balancing the fundamental tradeoff between performance and online computational time.","PeriodicalId":425118,"journal":{"name":"2021 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128025653","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}
