Internet of Things Positioning Technology Based Intelligent Delivery System

The fast growing of e-commerce makes the express delivery an important component of transportation system. Absent delivery as one of the main reasons of failed delivery, brings serious waste of resources every year. Although with the development of Internet of Things technology, positioning system of recipients' mobile devices can provide location information to help delivery routing optimization solving absent delivery, the lack of security makes it not practical. This paper proposes an IoT positioning technology based intelligent delivery system by introducing blockchain system and location information encryption, which overcomes three fatal problems of traditional IoT positioning technology based system: different party shares all information, location information interaction is too exposed and the system is unattractive to recipients. A set of analysis with real case experiment about efficiency improvement, incentive effect and security are conducted to validate the robustness of the system. Compared with previous research, the proposed system not only has high accuracy by utilizing real-time location information instead of unreliable prediction results, but also possesses high security.
