Bioinspired Mitigation Scheme for Cascading Failures in Farmland Wireless Sensor Networks

الملخص EN

Existing mitigation strategies on wireless sensor networks (WSNs) against cascading failures cannot appropriately adapt the particular characteristics of farmland WSNs.

Spider web provides a new reference for improving network invulnerability.

In this study, a bionic network scheme is built based on symmetric analysis of a series of spider-web vibration transmission trials, which include networking methodology, communication rules, and load capacity model.

The basic idea of this scheme is to apply the cascading-failure coping mechanism inspired by spider web into the construction and operation of farmland WSNs.

We found that the link backup contributed by a topological structure and communication rules had positive effects on suppressing the spread of cascading failures.

The study showed that the damages of cascading failures can be efficiently lowered by regulating the adjustment coefficient of the load capacity model.

The difference between the inner-layer node failures and outer-layer node failures for network invulnerability was verified under deliberate attack circumstances.

Based on these results, the proposed network scheme can be utilized to enhance the invulnerability performance of farmland WSNs.
