The swarm cognitive behavior of bees readily translates to swarm intelligence with social cognition, thus giving rise to the rapid promotion of survival skills and resource allocation. This paper presents a novel cognitively inspired artificial bee colony clustering (ABCC) algorithm with a clustering evaluation model to manage the energy consumption in cognitive wireless sensor networks (CWSNs). The ABCC algorithm can optimally align with the dynamics of the sensor nodes and cluster heads in CWSNs. These sensor nodes and cluster heads adapt to topological changes in the network graph over time. One of the major challenges with employing CWSNs is to maximize the lifetime of the networks. The ABCC algorithm is able to reduce and balance the energy consumption of nodes across the networks. Artificial bee colony (ABC) optimization is attractive for this application as the cognitive behaviors of artificial bees match perfectly with the intrinsic dynamics in cognitive wireless sensor networks. Additionally, it employs fewer control parameters compared to other heuristic algorithms, making identification of optimal parameter settings easier. Simulation results illustrate that the ABCC algorithm outperforms particle swarm optimisation (PSO), group search optimization (GSO), low-energy adaptive clustering hierarchy (LEACH), LEACH-centralized (LEACH-C), and hybrid energy-efficient distributed clustering (HEED) for energy management in CWSNs. Our proposed algorithm is increasingly superior to these other approaches as the number of nodes in the network grows.

3D motion model for the freefall lifeboat during its launching from a moving ship

Shaoyang Qiu, Hongxiang Ren, Naiyao Wang, Hongbo Liu

Summary: Studying the motion mechanism of a lifeboat's launch is crucial for ensuring marine evacuation safety. Motion modeling and simulation provide an effective approach to analyze the motion characteristics of lifeboat launches under different environmental conditions. However, current models for the complete launch process of a freefall lifeboat (FFLB) lack the latitudinal motion of both FFLB and its parent body, resulting in models with reduced accuracy and limited applicability. To address this issue, we propose a 3D motion model for FFLB launch from a moving ship using Kane's method. The model divides the launch process into sliding and water entry phases and considers the impact of ship motion and hydrodynamic forces on the lifeboat.
