Developing integrated Fog-Blockchain (FC-BC) applications requires a simulator. FoBSim enables validation of FC-BC protocols, showing BC deployment in the fog layer enhances efficiency.
Area of Science:
- Computer Science
- Distributed Systems
- Network Simulation
Background:
- Blockchain (BC) offers enhanced security, decentralization, and reliability but requires further development for widespread application.
- Fog Computing (FC) is an emerging paradigm crucial for future Internet of Things (IoT) environments.
- Integrating BC and FC presents significant research and development potential, with major tech organizations investing in this area.
Purpose of the Study:
- To introduce FoBSim, a novel simulation environment for validating integrated Fog-Blockchain approaches.
- To provide researchers and companies with a tool to reduce costs and efforts in testing FC-BC protocols.
- To facilitate experimentation with different Consensus Algorithms (CA), BC deployment options within FC, and BC functionalities.
Main Methods:
- Development of FoBSim, a dedicated Fog-Blockchain simulator.
- Implementation of various Consensus Algorithms (CA) and BC functionalities within the simulation framework.
- Simulation of different BC deployment strategies within the FC architecture.
Main Results:
- FoBSim successfully validates integrated Fog-Blockchain protocols.
- Analysis of simulation results demonstrates enhanced efficiency when deploying the BC network in the fog layer.
- Observed improvements in total run time and total storage cost with fog layer BC deployment.
Conclusions:
- FoBSim is a novel and valuable tool for the research community exploring Fog-Blockchain integration.
- Deploying Blockchain in the fog layer offers significant performance advantages for IoT environments.
- Further research and development in FC-BC integration are warranted, supported by effective simulation tools like FoBSim.
