Exploring Vibration Transmission Rule of an Artificial Spider Web for Potential Application in Invulnerability of Wireless Sensor Network

Abstract

Significant similarities exist between a spider web and wireless sensor network in terms of topology. Combining the unique advantages of the spider web in nature, such as invulnerability and robustness, with communication technology of a wireless sensor network presents high research value and broad development prospects. In this paper, a sort of a spiral artificial spider web based on 3D printing and its associated vibration testing device is proposed, which is used to study the transmission rule of vibration information of the spider web under given excitation conditions. It provides useful inspiration for establishment of an invulnerable communication rule of wireless sensor network. In order to investigate vibration transmission characteristics of the artificial spider web, vibration images are recorded and analyzed by a high-speed photography system, and vibration intensity is characterized by use of peak-to-peak value. Furthermore, vibration performance of the artificial spider web is studied under conditions of integrity and destruction, respectively. Our test observation reveals the vibration transmission rule of the unique structure of the spider web, providing a novel analysis method for improving invulnerability of the wireless sensor network.

Bioinspired Mitigation Scheme for Cascading Failures in Farmland Wireless Sensor Networks

“…We use the developed artificial spider-web vibration testbed (Figure 1) to clarify the cascading spread characteristics of spider web after damage to partial components [26]. In the experiments, a rubber ball with a mass of 20 g and a diameter of 50 mm is utilized as the excitation source.…”

Structure Design and Optimization of the C5–C6 Cervical Intervertebral Fusion Cage Using the Anterior Cervical Plate and Cage Fixation System

“…The cage design in this study was guided by the concept of bionics, which is an interdisciplinary subject taking various scientific ideas and engineering solutions from nature. Bionics is divided into several categories: structural bionics [ 15 ], mechanical bionics [ 16 ], control bionics [ 17 ], and information bionics [ 18 ]. The human cervical intervertebral disc is an indigenous component that can be used as a natural bionic prototype.…”
