Abstract:
Structural health monitoring is the fact of estimating the state of structural health, or detecting the changes in structure that affect its performance. The traditional approach to monitor the structural health is by using centralized data acquisition hub wired to tens or even hundreds of sensors, and the installation and maintenance of these cabled systems represent significant concerns, prompting the move toward wireless sensor network. As cost effectiveness and energy efficiency is a major concern, our main interest is to reduce the amount of overhead while keeping our health monitoring accurate. Our contribution to this structural health monitoring will be to reduce the amount of data to be transmitted that is by compressing the payload of the packets using a compression algorithm and by doing so, we will extend the lifetime of the battery, thus the capacity of the sensor node will increase since less time will be taken to transmit data between intermediate node as well as the node coordinator..
