TEMBUV: Trust Ensuring Mechanism Based on Blockchain using UAVs and VANETs

After disasters, the resulting destruction often leads to disruptions in internet and communication, making search and rescue efforts in disaster zones more challenging. Depending on the scale of the disaster area, it is observed that the government-owned vehicles become insufficient. To address these issues, we have developed a blockchain-based trust mechanism to include and regulate privately owned vehicles whose reliability upon entry is uncertain. We propose a blockchain-integrated trust mechanism where everyone can vote to identify malicious components. Our system employs a credit-based DPoS consensus mechanism to ensure reliability. Additionally, we have conducted simulations of our system, testing against various attack models, and subsequently, we have evaluated the results across different metrics. We have assessed the results with metrics ACC (accurate trust decision rate) and Secure Witness Ratio (SWR). Each test shows more than a 90% success rate. We have compared our model with the closest work in the literature LVBS [1]. The tests showed considerable improvement.
