Ensuring Data Security and Routing Efficiency in Warehouse Sensor Networks Using Wireless Blockchain Technology

The integration of wireless sensor networks (WSNs) and blockchain technology has gained significant attention in recent years due to its potential in addressing security and privacy concerns in various applications. In this paper, we propose blockchain technology with wireless-based secure warehouse system (BCWS2) that leverages wireless blockchain technology along with an efficient routing policy to ensure data integrity, authenticity, and confidentiality in a warehouse environment. The proposed system consists of a network of battery-powered wireless sensors deployed within the warehouse premises to monitor various environmental parameters such as temperature, humidity, and light levels. These sensors collect data and transmit it securely to a blockchain network using cryptographic techniques to prevent unauthorized access and tampering. The blockchain network, powered by smart contracts, acts as a decentralized ledger, ensuring the immutability and transparency of the collected sensor data. Each sensor node contributes to the blockchain by forming a consensus on the validity of the data through a distributed consensus protocol. This enables secure and tamper-proof storage of the collected data, eliminating the need for a central authority or trusted intermediary. In order to enhance routing efficiency within the warehouse sensor network, we present a highly efficient routing policy that leverages machine learning algorithms. Our proposed routing policy aims to optimize the path selection process, ensuring effective and streamlined communication within the network. The policy dynamically adjusts the routing paths based on the current network conditions, such as node congestion, battery levels, and signal strength. The proposed routing approach significantly enhances network performance, minimizes energy consumption, and guarantees prompt delivery of sensor data to the blockchain network. This system effectively tackles various challenges encountered in conventional warehouse sensor networks, such as data integrity, security, and scalability. By harnessing wireless blockchain technology and implementing an efficient routing policy, the system offers a resilient and secure solution for monitoring and administering warehouse environments.
