Two-Dimensional Behavior Marker-Based Data Forwarding Incentive Scheme for Fog Computing-Based SIoVs

In social Internet of Vehicles (SIoVs), vehicles can usually act as data-relaying nodes to forward data. However, vehicle nodes often show their personal and social selfishness in data forwarding (namely vehicle nodes are not willing to forward data), whose selfishness greatly influences the delivery ratio of data forwarding. In this article, we propose a 2-D behavior marker-based data-forwarding incentive scheme to motivate vehicle nodes to participate in data forwarding in fog computing-based SIoVs. First, we design a 2-D behavior marker mechanism, which can be used to completely evaluate vehicle nodes. Second, we construct a currency credit-based data-forwarding incentive strategy based on the 2-D marker and the social attributes of vehicle nodes, which is used to deal with vehicular normal behavior, vehicular selfish behavior, and vehicular malicious behavior. Compared with other related schemes, our proposed scheme can completely evaluate the behaviors of vehicle nodes and can further promote the cooperation of data-forwarding between selfish nodes. The experimental results show that our scheme is more efficient and stable in data forwarding in fog computing-based SIoVs.

Automated summary

This article introduces a data-forwarding incentive scheme based on 2-D behavior markers to encourage vehicle nodes to participate in data forwarding, improving data delivery ratio. By evaluating the behaviors of vehicle nodes comprehensively, cooperation between selfish nodes in data forwarding is promoted.
