In particular, the eavesdropper intends to wiretap the transmitted signals from the source. Two of the near users are picked up, served as a wireless-powered relay and a wireless friendly jammer, respectively. We propose a user selection and cooperative jamming based secure transmission scheme. Specifically, the source transmits a superimposed signal to the selected near user. The selected near user, who is employed as a relay, can harvest energy from the radio frequency signals and decode the information simultaneously. The harvested energy are then utilized to forward the signal to the far user. The jammer also collects energy from the source, and emits artificial noise by using the harvested energy to confuse the eavesdropper. Based on the proposed scheme, the closed-form expression for secrecy outage probability (SOP) and effective secrecy throughput (EST) are derived. The correctness of our theoretical analysis is verified by Monte-Carlo simulations, and the superiority of the proposed scheme in improving the system secure performance is also validated.","PeriodicalId":201450,"journal":{"name":"2023 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122967593","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 SVC, group-of-picture (GoP) structure is a base unit consisting of a sequence of frames and its structure contains a periodic relationship among them. Hence, the GoP structure not only determines the efficiency of SVC encoder, but also impacts on the video quality of a decoder output. However, the conventional representation systems could not clearly represent the GoP structure for both the encoder and decoder. Additionally, there is lack of theoretical study on the achievable performance of the encoder/decoder. To address this, this paper focuses on quantitative analysis of the GoP structure from the perspective of information theory. We propose to represent the GoP structure by introducing and extending the probabilistic graphic model which is proposed as a methodology in machine learning society. By the proposed representation system, the information compression of video is formulated for the encoder/decoder with closed-form expression. Based on this, we quantify the video information for GoP and propose a methodology to optimize the achievable performance of a given GoP in the view of information theory. The proposed representation and optimization methods are valuable to design an efficient GoP structure.","PeriodicalId":201450,"journal":{"name":"2023 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115911594","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 achieve reliable cooperation for safety critical CAV driving applications, an important but rarely studied issue is identifying communication vehicles of interests from sensed vehicles (ICSV). Wrong vehicle identification may cause unsafe driving decisions and lead to potential accidents. In this paper we study the ICSV problem for safe cooperative autonomous driving. We present a location based baseline method for ICSV and discuss its potential problems. Then we propose a cooperative method to improve reliability and accuracy. In the proposed method vehicle registration number (VRN) is used for vehicle identification. And multiple CAVs can cooperate on both sensing and identifying communication vehicles from their detected ones. VRNs can be hashed before sharing to protect privacy, and are compared to the shared ones for vehicle identification. Experiment results show that the approach is feasible and can have a very low false positive rate.","PeriodicalId":201450,"journal":{"name":"2023 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"629 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116405713","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}

Achieving efficient resource allocation for different services and applications requires a unified abstraction of available resources, which is commonly known as Network Slicing. However, allocating resources among slices becomes a non-trivial problem due to the limited resources and unpredictable requirements of different services. In this paper, we study a dynamic RAN slicing framework incorporating multiple base stations, where workload distribution, radio spectrum and computing resource allocation decisions are made to meet diverse Quality of Service (QoS) requirements. Specifically, delay-tolerant and delay-sensitive services are considered. The unit resource allocation costs are considered to be time-varying. Furthermore, the unit resource allocation costs and QoS requirements are considered to be unknown before making workload distribution and resource allocation decisions. We propose an Online Convex Optimization (OCO) approach for the RAN slicing framework in order to minimize the overall cost and satisfy the QoS constraints in the long run. Simulation results and comparison with two baselines demonstrate that our algorithm outperforms the baselines while satisfying QoS constraints in long-term.","PeriodicalId":201450,"journal":{"name":"2023 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129403529","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}

Most studies of IDNC in the literature focus on the fully-online feedback mode, and Maximum Weight Vertex Search (MWVS) is an efficient algorithm to generate IDNC packets with the best-known completion delay performance. In this paper, we investigate IDNC for semi-online feedback transmission, in which the sender generates and broadcasts INDC packets round by round and collects feedback only after every round. Even though MWVS can be exploited to construct an IDNC scheme for semi-online feedback transmission, we demonstrate by an explicit example that such one may not have the optimal completion delay. We then modify MWVS so as to improve the completion delay performance of the constructed IDNC scheme. Moreover, we reveal that compared with the uncoded scheme, IDNC schemes constructed by existing fully-online feedback algorithms may not reduce the expected number of transmission rounds. We then design an efficient algorithm to construct IDNC schemes with fewer transmission rounds. Numerical analyses demonstrate an approximately 10% performance gain of the IDNC scheme constructed by our proposed algorithms over the one constructed by MWVS in terms of both completion delay and transmission rounds.","PeriodicalId":201450,"journal":{"name":"2023 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126969593","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}

Due to the IoUT devices’ wide-area distribution and constrained transmit power, autonomous underwater vehicles (AUVs) have become extensively employed for data collection in underwater environments. Ensuring the reliability of underwater tasks, the autonomous obstacle avoidance of AUV swarms has emerged as a critical research area. The Multi-Agent Deep Deterministic Policy Gradient algorithm (MADDPG), which employs centralized training and distributed execution, is an effective method to address this problem. However, current studies often overlook the complex dynamic underwater environment, including the interference caused by ocean currents on AUV movement and the observation noise of objects in the ocean. To adapt to the interference of ocean currents on AUV movement, we establish a two-dimensional motion model for AUVs. This model enables us to transform the output of MADDPG into propulsion force and steering gear control force, effectively accounting for ocean current disturbances. To tackle the observation noise of obstacles in underwater environment, we first assume the obstacle is moving in uniform linear motion, and then use the Kalman filtering algorithm to process the observed signals. Our simulation results demonstrate the superiority of our scheme.","PeriodicalId":201450,"journal":{"name":"2023 IEEE/CIC International Conference on Communications in China (ICCC Workshops)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127923737","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}
