Blockchain for Emergency Vehicle Routing in Healthcare Services: An Integrated Secure and Trustworthy System

Healthcare is one of the most important sector where security is a major concern in Internet of Things integrated healthcare. The future generation vehicles are enabled with features of autonomous driving and accurate decision making. We can use such features in emergency vehicle routing with the help of Blockchain technology for collecting trustworthy road network information. In this work, we design and develop an emergency vehicle routing solution where each vehicle connects to the Ethereum Blockchain integrated with Open Source Routing Machine (OSRM). Blockchain enables secure information sharing among vehicles and the OSRM provides shortest trustworthy routes. The proposed approach reduces transit delay of the emergency vehicles while providing emergency healthcare services. Furthermore, the efficacy of the proposed approach has been shown through experimentation by implementing a smart contract in Blockchain based trust-worthy vehicle route generation.
