Bio-inspired routing protocol uses a principle of swarm intelligence, which finds the optimal path to the destination in a distributed and autonomous way in dynamic environments, so that it can maximize routing performances, reduce control overhead, and recover a path failure quickly according to the change of network topology. In this paper, we propose a bio-inspired routing protocol for mobile ad hoc networks. The proposed scheme uses a function of overhearing via wireless media in order to obtain the routing information without additional overhead. Through overhearing, the pheromone is diffused around the shortest path between the source and destination. Based on this diffused pheromone, a probabilistic path exploration is executed and the useful alternative routes between the source and destination are collected. Therefore, the proposed routing protocol can ensure the up-to-date routing information while reducing the control overhead. The simulation results show that the proposed scheme outperforms the typical AODV and AntHocNet protocols in terms of routing performances and significantly decreases the routing overhead against the AntHocNet.

This paper investigates the capture of a 12U-sized CubeSat space object using a spider-web structure-based space net. The structural dynamics analysis program ABAQUS is used to simulate the shock-absorbing capability of the space net with a diagonal length of 2.828 m. The space object is modelled as a rigid body, and the space net is modelled using non-linear elastic beam elements. The simulations reveal that the spider-web structure-based space net outperforms the squared space net of the same structural weight in capturing the space object. The numerical simulations are conducted to examine the successful or unsuccessful captures of the space object in various cooperative and non-cooperative motions.

We fabricated a 3D knee joint model through the imaging processing. The 3D shape information is different depends on specific conditions when the shape of real knee joint is extracted from CT/MRI sliced images. The two types of joint models were fabricated by using 3D printer in order to analysis of joint movement by slight difference of 3D shape information. The compressive force experiments were performed by using knee joint model. As the results, the compressive forces were changed with respect to the difference of geometry. Consequently, feasibility test should be performed before developing biomimetic bioreactor.

This study explores the organic form generation method, which reflects the evolving biomimetic approaches converging in fashion technology and considers the characteristics of the organic relationship between the body and the clothing to be represented in contemporary fashion. A literature review on biomimetic architecture and design-related theory and a case study on biomimetic fashion were both conducted. Images, articles, and data related to biomimicry fashion and clothing, including the increase in virtual fashion cases around 2020, were analyzed based on the literature review. Biomimicry was used to derive interdisciplinary similarities in the organic morphogenesis principle, and the result was categorized as a network system, folds and unfolds, pneumatic structures, auxetic growth, and membranes. The biomimetic fashion characteristics, including externalization of the body's interior, expansion of the body structure and silhouette, body protection, independence from the body, and post-human expression through virtualization, were analyzed. Morphogenetic processes performed through biomimetic vision are expected to aid in generating research on the possibility of mass production or popularization in the future through various experimental technical studies.
