Optimized Data Exchange And Storage In Blockchain- Enabled Edge Computing Environments

Abstract

The rapid proliferation of Internet of Things (IoT) devices and the deployment of 5G networks have significantly increased data generation at the network edge. Traditional centralized data trading platforms introduce challenges such as high latency, security vulnerabilities, and unfair pricing models. This paper presents a decentralized framework for secure and cost-efficient data exchange in edge computing environments using blockchain technology. A hybrid consensus mechanism, Proof-of-Data-Trading (PoDT), is proposed to ensure secure and energy-efficient validation of transactions. Additionally, a Rounding-based Data Placement Algorithm (RDPA) is introduced to optimize data distribution across relay nodes, reducing storage and transmission costs. The system enables peer-to-peer data trading among producers, relays, and consumers while ensuring transparency, integrity, and fair incentive distribution. Experimental analysis demonstrates improved performance in terms of latency, cost efficiency, and security compared to traditional approaches.
