# Resource Management and Secure Data Exchange for Mobile Sensors Using Ethereum Blockchain
## 6 Conclusions and Outlook  
This paper presents a novel solution to address the challenges of adopting the Ethereum blockchain for resource management while strengthening security. Irrespective of including N2N and N2S communication modes, a novel consensus mechanism, and a cost model, the proposed scheme managed a streamlined balance among all the considered performance evaluation metrics. It maintains an optimal resource management performance with better consistency when increasing traffic load. The implemented scheme not only improves the security strength of the Ethereum blockchain but also successfully maintains optimal performance in data transmission and responsiveness. A resource-efficient mechanism using N2N and N2S communication modes with mobile sensors was presented in the proposed scheme to validate sensory devices in mobile sensors for network structures using the Ethereum blockchain, with computed trust scores further ascertaining the node authenticity. A cost model with a multi-objective function was proposed to reduce the cost of mobile sensors in data transmission tasks. Unlike existing blockchain approaches that use sophisticated encryption schemes, the proposed method employs a simplified finite field and hashing during sensor enrollment, thereby introducing a novel consensus mechanism in which an access point acts as a follower, auxiliary, and leader for better blockchain adaptability in dynamic sensor networks. Performance benchmarking shows that the proposed scheme reduces the validation time by 40%, latency by 28%, overhead by 38%, processing time by 38%, and cost by 27%, and improves throughput by 23%.  
Future work will optimize this model by considering it as a baseline and incorporating preemptive measures to mitigate bottleneck conditions at variable resource saturation points for mobile nodes. Integrating the Ethereum blockchain with IoT platforms can provide a standardized framework for managing mobile sensor networks, enabling seamless interoperability between different sensor devices and facilitating data exchange and coordination to prevent congestion. Ethereum smart contracts can be programmed to manage mobile sensor resources efficiently, allocate bandwidth and processing power based on demand, and prioritize critical data transmissions to reduce bottleneck conditions. Additionally, using Ethereum's native cryptocurrency, Ether, for micropayments and incentives can encourage mobile sensors to cooperate in lowering bottleneck conditionsby rewarding them for relaying data, providing computational resources, or adopting energy-saving behaviors.
