Enhancing Address Information Legitimacy in MANET with Blockchain

MANET operates autonomously without central-ized administration, which poses the risk of malicious behavior by sinister nodes. Address duplication detection, in particular, is an inevitable function of network operation and requires legitimacy in its results. In this paper, we propose a method using blockchain in MANET to ensure the legitimacy of address information. To evaluate the effectiveness of our approach, we measured address duplication detection times and found that while blockchain implementation added some overhead, it significantly reduced detection times compared to an existing method.
