This paper addresses a sensor system dedicated to monitor a large mechanical machine. This sensor system is based on a wireless sensor network whose special feature is the mobility of one or more nodes following an invariant path traveled repeatedly. In the study described here the path is a circle. The topology chosen is that of locating relays on the mobile system that has appropriate geometric characteristics. A new dynamic routing algorithm is proposed. It uses the location and moving speed of mobile nodes to choose the optimal route of the packets forwarded to the fixed sink. Network performance is evaluated in terms of delivery time and packet loss rate and compared to this obtained by using flooding routing protocol. The results show that the proposed architecture and mechanisms deliver the appropriate quality of service for the monitoring of large physical systems.
