Translated title:
Ensuring consensus on trust issues in capability-limited node networks with Blockchain technology
Summary:
In this thesis, we review how the blockchain protocol could be applied so as to ensure the consensus of the network nodes on matters of trust, while taking into account the limited resources of the nodes. First, we will present the system we will be working on, a Mobile Ad Hoc Network (MANET) which uses a clustering scheme, based on the cost of analysis/processing concept, along with a trust mechanism that together result in cluster persistence and quick discovery of malicious nodes. Then, we will introduce the blockchain protocol and its main concepts. A review of related work will be conducted to assess the various approaches utilized by others in incorporating the blockchain protocol into their respective systems. Subsequently, the Hyperledger Fabric framework, which shall aid in the implementation of the proposed system, shall be presented in detail. Finally, the proposed system, which merges the given MANET simulation with the blockchain technology enabled by Hyperledger Fabric, will be presented, and its results discussed. Our analysis will also include an evaluation of its effectiveness in addressing consensus on trust issues, and possible avenues for future enhancements.
