Quantitative Invulnerability Analysis of Artificial Spider-Web Topology Model Based on End-to-End Delay

Abstract

This paper presents an artificial spider-web topology model inspired by the structure and invulnerability of a spider web. A hierarchical clustering routing rule is accordingly established using the vibration transmission features of the natural spider web as a reference. Furthermore, the end-to-end delay is applied as the quantitative indicator of invulnerability for analyzing the communication performance and characteristics of the artificial spider-web topology. The simulation tests of a one-layer and 3-layer artificial spider-web model are implemented to obtain the importance and destructive tolerance of network components based on OPNET, with the change of communication conditions and fault types. This paper can provide a practical analysis method for the invulnerability of the artificial spider-web topology and offer important implications for the construction and maintenance of wireless sensor networks based on the topology.

Bioinspired Mitigation Scheme for Cascading Failures in Farmland Wireless Sensor Networks

“…erefore, on the basis of the inspirations of artificial spider-web topology against cascading failures (topological structures, node deployment mode, and link backup mechanism), combining with the characteristics of farmland WSNs, we should be able to develop a bionic network scheme to alleviate the cascading effect for potential network attacks. Furthermore, the artificial spider-web topology has been proven to be more invulnerable than other traditional topologies in harsh network environments, with the possibility for improving the capability of farmland WSNs against cascading failures [27].…”
