Summary: This paper proposes an innovative topology optimization approach that can handle both static and dynamic cases, as well as multiple objectives and loads. The key idea is the input-to-output transfer matrix, which is decomposed using singular value decomposition to determine the mapping between inputs and outputs. The paper provides detailed numerical examples and highlights ongoing investigations for further research.

Summary: This article proposes a new energy-aware network topology obfuscation mechanism that maximizes the attack costs and is efficient and practical to be deployed. The proposed mechanism includes a route obfuscation method based on ranking-based route mutation and a sink node obfuscation method based on the k-anonymity model. Extensive simulation results demonstrate that the proposed methods can effectively mitigate traffic analysis attacks and achieve effective network topology obfuscation for software-defined wireless sensor networks.

Summary: In integrated sensing and communications (ISAC), channel information is obtained through the channel knowledge map (CKM). However, a common angle of arrival error (CAE) occurs due to the lack of precise user equipment heading knowledge, causing non-orthogonality among data layers for SVD-based precoding. This study develops two algorithms utilizing rotational effects to estimate and eliminate the CAE, suitable for low and high Rician K-factor scenarios. The proposed algorithms achieve higher precoding performance compared to the baseline method, providing accurate wideband channel information based on narrowband reference signals.
