Method for Creating Networks between Vehicles to Monitor Vehicle Condition

抄録

Wireless sensor networks have been used over recent years to monitor the condition of railway facilities. This paper focuses on wireless sensor networks designed to monitor the condition of train vehicles. To collect measurement data from sensors installed on each vehicle a network needs to be created between vehicles so that data in the sensors can be transmitted to the collection device via an appropriate route. However, coupling or decoupling raises the issue of how to modify networks when train composition is changed. As such, this paper proposes a two-tiered network composed of a single vehicle network and a multiple vehicle network, and describes the development of a method for creating multiple vehicle networks. This paper reports test results on a prototype system and results from a simulation using the proposed method.
