Section 1. Introduction (Around 300 words)

  • Blockchain technology in scheduling systems (no need to explain what is Blockchain)
  • Use technologies like the Latest version of Hyperledger Fabric (a permissioned blockchain), Chainstack (Blockchain as a Service), Angular (Web framework as system’s front-end), IPFS (InterPlanetary File System) to create a task scheduling and planning system for Satellite Observation, as a proof of concept (an experimental simulation).
  • Then Evaluate the performance of the created system with tools like Hyperledger caliper.

Section 2. Blockchain technology in scheduling systems (task/resource scheduling) (Around 300 words)

  • How blockchain can help scheduling systems (planning tasks for Electrical Vehicle (EV), Satellite, unmanned aerial vehicle (UAV), radars, etc.) to increase trust, enhance security, and ensure privacy, etc.
  • Such as, the predetermined task scheduling/planning scheme will be generated through the planning system with the Planning algorithms and stored in a traditional database system. Then the designated personnel will make adjustments on the predetermined task scheduling/planning scheme and produce the final planning scheme to use on the Electrical Vehicle (EV), Satellite, Unmanned aerial vehicle (UAV), radars, etc
  • Blockchain technology can be used for scheduling systems to ensure the data integrity, since someone with access may want to change the planning scheme for their personal gains. (e.g., someone only pay for Satellite to observe certain area, but he may change the final planning schedule and let the Satellite to observe more area, illegal area, or different areas than it was originally planned, use the Satellite resources for its personal gain)

Section 7. Motivation of using Hyperledger fabric blockchain technology on Task Scheduling and Planning for Satellite observation (Around 250 words)

  • Hyperledger is a Permissioned blockchain that provides permissioned access to different members and organizations involved in the system.
  • It gives trust to the otherwise trustless environment between organizations and members
  • It gives Auditability to the system since the business logic/rules (the smart contracts in general blockchain systems), also known as chaincode in Hyperledger fabric, cannot be easily altered and any updates to the chaincode (the business rules) will be known by all parties and will need to be approved by all important parties involved.
  • It also increases the integrity of the data stored in the blockchain
  • Hyperledger fabric 2.0 provides increased Security and privacy protection to the data and parties involved.
  • Hyperledger is a blockchain that developed for enterprise
  • Satellite network and data transmission need security and privacy, task planning scheme in Satellite task planning needs trust and data integrity that traditional Satellite planning systems lack, etc.

 

Section 8. Our proposal (Around 250 words)

  • A Blockchain-Based Permissioned Satellite Task Scheduling and Planning system, which Use technologies like the Latest version of Hyperledger Fabric (a permissioned blockchain), Chainstack (Blockchain as a Service), Angular (Web framework), IPFS (InterPlanetary File System).
  • The flow of the system is basically as follows: the predetermined task scheduling/planning scheme for Satellite observation will be generated through the planning system with the Planning algorithms, and uploaded and stored in the IPFS (off-chain storage) and the returned hash will be stored into the blockchain itself to save on-chain storage space (since the storage on the blockchain is expensive and the on-chain storage should only store the utmost important information/data). Then the designated personnel will make adjustments on the predetermined task scheduling/planning scheme and produce the final planning scheme, this final planning scheme will be stored directly into the blockchain storage since it is important to not change the planned data at this stage or to record every changes/modifications happened after this stage.
  • This is to ensure the data integrity, since someone with access may want to change the planning scheme for their personal gains.
  • (For this part only description is needed, I will add figures and more details myself)
