Wireless sensor networks based on bridge safety monitoring system

Under the bridge to monitor the needs of security parameters, based on wireless sensor network technology to monitor bridge safety system to achieve the program; on the overall system structure and working principle of the node set, sub-clusters and key technologies, While recent developments in wireless sensor networks have demonstrated their potential to provide continuous structural response data to quantitatively assess structural health, many important issues including network lifetime and stability, damage detection reliability, such as congestion control for the discussion.
