Abstract
Most management systems that are currently in place to monitor the safety of bridges - working in conjunction with a wireless sensor network - are based on a wired infrastructure. Not only do these wired systems expensive to install, but they are expensive to replace or repair should a problem occur with the system while in operation. In an effort to address these problems, there have been many researches that attempted to use a wireless sensor network for the existing wired measurement system. However, they have been met with difficulty due to the problems of power and synchronization in actually bringing the management system to the bridges as a commercial system. This paper proposes a bridge management system based on WSN (Wireless Sensor Network) which uses wireless LAN technology. The system was tested using a testbed and when the obtained data were compared to the data collected using the existing wired counterpart it was found that they were almost the same.
