چکیده :

The exponential growth of connected devices in smart homes and urban infrastructures has significantly increased broadband consumption, creating challenges such as network congestion, security vulnerabilities, and inefficient utilization of available bandwidth. This paper presents a blockchain-enabled decentralized smart marketplace (SMP) that allows users to securely trade surplus Internet bandwidth in a transparent, cost-effective, and autonomous manner. Unlike traditional centralized Internet Service Providers (ISPs), the proposed model leverages smart contracts and a Proof-of-Authority (PoA) consensus mechanism to ensure data integrity, trustless transactions, and energy-efficient validation. The marketplace allows smart home users to monetize their idle bandwidth resources, while buyers benefit from on-demand, verified, and lower-cost access to Internet capacity. The designed system demonstrates that applying blockchain in bandwidth trading can significantly reduce bandwidth waste, improve channel utilization, and foster a sustainable digital economy for next-generation smart cities. Simulation and analytical observations confirm that the model can minimize bandwidth wastage by up to 75% and maintain high transaction reliability with minimal computational overhead.
