Aiming at the tourism informationization is difficult to meet the needs of passengers and massive data processing changes day by day, this paper puts forward a solution based on WSN wisdom travel. The scheme will be the tourism resources virtualization to frame a wisdom tourism cloud platform based on cloud computing IAAS, PAAS and SAAS model, and use cloud computing and open source software OpenStack, Hadoop architecture design. The purpose enable the tourism resources of wisdom navel cloud system into one unified management, unified sales, unified treatment and unified service. Thus the system implement the tourism industry cluster and the collaborative development of tourism resources, improve the information processing capacity and reliability. 展开更多
