Efficient resource allocation is critical for mobile adhoc networks due to their dynamic and decentralised nature. The integration of quantum computing techniques with the Vickrey Clarke Groves (VCG) auction mechanism offers a promising solution for optimising resource allocation. This paper proposes a Quantum enhanced VCG Auction (QVCG) framework that leverages quantum inspired algorithms to address computational complexity and enhance decision making precision. Experimental analysis demonstrates that QVCG achieves improved fairness, efficiency, and security in resource allocation, particularly in environments with high node mobility and constrained resources. The findings establish QVCG as a robust mechanism for supporting real-time and adaptive resource management in MANETs.
