Integrated sensing and communication (ISAC) emerges as a critical technology for future 6G cellular networks. The distinct nature of sensing-centric and communication-centric waveforms poses a challenge, as a unified design can lead to a performance tradeoff between sensing and communication. Most of the previous studies focused on single ISAC base station (BS) scenarios and explored capacity-distortion tradeoffs for various ISAC channels. However, practical scenarios involve multiple ISAC BSs in the same region, sharing time-frequency resources and causing interference, which impacts both sensing and communication functions. To address this challenge, we propose an information-theoretic modeling of monostatic ISAC over interference channels. In the model, two interfering ISAC BSs seek to communicate with their users while performing sensing estimation through received echo signals. An achievable scheme is developed for the considered model, utilizing superposition coding and joint compression of past transmitted codewords and echo signals via distributed Wyner-Ziv coding. The corresponding achievable rate-distortion region is characterized, and a specific example is provided to demonstrate the advantages of the proposed scheme. Our results highlight that interference links, in conjunction with echo signals, can be strategically leveraged to achieve unified cooperative sensing and communication between the two BS-user pairs.

This paper provides a new solution of unmanned ship control with unmeasurable yaw angle in complex communication environments. A new adaptive output feedback controller is designed in this paper to ensure that the position error converges to zero asymptotically and meets the prescribed performance requirement. It is revealed that the designed control law can make sure that the tracking deviation convergence is not affected by the yaw angle estimated error. A simulation example is designed and completed to demonstrate the validity of the proposed controller.

To improve the sum rate, this paper investigates a Non-Orthogonal Multiple Access (NOMA) network assisted by Simultaneous-Transmitting-and-Reflecting (STAR) Reconfigurable Intelligent Surface (RIS). We utilize NOMA, Deep Reinforcement Learning (DRL), and STAR-RIS technologies to enhance signal reception and interference cancellation at the user. Our simulation results indicate that: 1) DRL NOMA achieves signal enhancement through interference cancellation and power allocation;2) Sum rate fluctuates with changes in RIS elements count, enabling the selection of the optimal quantity of STAR-RIS based on the transmit power;3) Different activation functions have varied suitable power ranges, allowing for the choice of activation function types based on transmit power.

With the rapid development of network technology and terminal devices, we have entered a digital age, where data generation and exchange have become the core of modern society. In this context, green computing and communication issues are becoming increasingly important. Traditional key management methods have some issues, including centralization risks, high energy consumption, and complex management processes. These problems are contrary to the principles of green computing and communication. The introduction of blockchain and group key technologies provides an innovative approach to solving these issues. Firstly, blockchain utilizes a decentralized distributed ledger that disperses key management tasks to multiple nodes within the network. This reduces centralization risks and enhances the security and trustworthiness of the system. Additionally, blockchain transaction records are tamper-resistant, ensuring transparency and traceability in data exchange. Moreover, blockchain-based group key management methods help reduce the need for centralized servers, thus decreasing energy consumption and aligning with the principles of green computing. In this context, this paper proposes a blockchain-based group key management method for edge device transactions. This method constructs groups based on the inherent attributes of edge device nodes, and effectively reduces the system overhead caused by rederiving new keys due to node additions or removals within the group, as well as the key transmission between nodes. The paper first utilized OpenEthereum to build a blockchain network for testing the proposed group key management algorithm, thus demonstrating the scalability of the proposed solution.
