Wireless sensor networks (WSN) are proving to be a good fit where real time monitoring of multiple physical
parameters is required. In many applications such as structural health monitoring, patient data monitoring, traffic
accident monitoring and analysis, sensor networks may involve interface with conventional P2P systems and it is
challenging to handle heterogeneous network systems. Heterogeneous deployments will become increasingly
prevalent as it allows for systems to seamlessly integrate and interoperate especially when it comes to applications
involving monitoring of large infrastructures. Such networks may have wireless sensor network overlaid on a
conventional computer network to pick up data from one distant location and carry out the analysis after relaying it
over to another distant location.
This paper discusses monitoring of bridges using WSN. As a test bed, a heterogeneous network of WSN and
conventional P2P together with a combination of sensing devices (including vibration and strain) is to be used on a
bridge model. Issues related to condition assessment of the bridge for situations including faults, overloads, etc., as
well as analysis of network and system performance will be discussed. When conducted under controlled conditions,
this is an important step towards fine tuning the monitoring system for recommendation of permanent mounting of sensors and collecting data that can help in the development of new methods for inspection and evaluation of bridges. The proposed model, design, and issues therein will be discussed, along with its implementation and results.
