Securing Collaborative Environment Monitoring in Smart Cities Using Blockchain Enabled Software-Defined Internet of Drones

The Internet of Drones (IoD) is a layered network control architecture, which having revolutionary impact on the monitoring and preservationvof environment. Large-scale drone-assisted environmental can provide better perspective high-quality data by operation critical components smart cities. However, with continuous expansion IoD scale increase multi-drone collaboration tasks, large-scale service in cities will inevitably encounter problem relay transfer drone control. Lack trust paradigm between controllers bring huge security challenges to real-time environment, data, location privacy drones, so on. To address this important issue IoD, article proposes that uses contracts blockchain ensure trusted software defined (SD-IoD). First, we propose novel SD-IoD architecture enhance support for heterogeneity flexibility Second, controller consortium secure efficient cooperation interoperability controllers, includes new cryptographic currency coin consensus mechanism proof guarantee (PoSG). Third, have designed incentive encourage maintain their safer services other controllers. analysis performance simulation results indicate effectiveness proposed mechanism.
