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.

A spider web is an essential medium for a spider’s hunting and habitation
Watanabe discussed whether changing the tension of radial or spiral lines will affect the response speed of spiders, and the result showed that changing tension of spiral lines has little effect on the vibration information perceived by the spider, while increasing tension of radial lines makes it possible for the spider to detect smaller preys [3]
The results show that before the artificial spider web is damaged, impact of the small ball is borne by all nodes of the whole network
Summary
A spider web is an essential medium for a spider’s hunting and habitation. After billions of years of evolution, it has become an elegant and almost perfect existence. Spider webs can maintain strong and effective connections and quickly perceive vibration information in case of damage to several meshes. Watanabe discussed whether changing the tension of radial or spiral lines will affect the response speed of spiders, and the result showed that changing tension of spiral lines has little effect on the vibration information perceived by the spider, while increasing tension of radial lines makes it possible for the spider to detect smaller preys [3]. Sadati and Thomas preliminarily investigated morphological computation aspects in naturally spun webs for providing analysis support in the form of a mechanical signal processing system and briefly discussed the web transverse signal filtering, attenuation, delay, memory effect, and deformation modes based on experimental data and numerical simulations [4]
