Public Bicycle Operating System Based on Space-Time Security and the Internet of Things

The bad behaviors of some users and the drawbacks of public bicycles have hindered the promotion of public bicycles. The current problems include low utilization rate, uneven distribution, high loss rate and insecure lock. However, there is few feasible research in this new field. To address these issues of public bicycles, we propose a public bicycle operating system(PBOS). PBOS involves three key technologies: 1) To acquire a dynamic password and realize bicycle self-rescue, we devise an intelligent lock that utilizes the Internet of Things (IoT) to establish Bluetooth connection with user’s mobile phone. 2) To avoid bicycle loss and improve the security of data transmission, we design a space-time security protocol to work between bicycle’s intelligent lock, mobile app, and server. 3) To increase the average utilization rate and distribution, we present a cooperative game model for bicycle scheduling. Finally, we evaluate the performance and validate the theoretical properties of PBOS through extensive simulations.
