Routing Protocols for Structural Health Monitoring of Bridges Using Wireless Sensor Networks

Monitoring older bridges using Wireless Sensor Networks (WSNs) has had a lot of atten-tion in recent years. In much of this research tasks like sensor data processing, environment states and events decision making are done by a remote server. A Structural Health Monitoring (SHM) application using WSNs to provide the data collection necessary for rapid structural assessment after an event such as a natural disaster has been simulated in this paper. Efficient MAC and routing protocols must be designed for the proposed application to offer a guarantee for the reliability of the data delivered from source nodes to a sink. The number of deliv-ered reports, delay and the lifetime of the network are considered in the proposed application. As a result, a new cross layer protocol based on MAC and routing protocols is designed and simulated for SHM application taking different scenarios into consideration and results are pre-sented in this paper. Simulation results show that the proposed protocol increases performance of the target application, in varies scenarios
