Abstract
The rapid advances in processor, memory, and radio technology have enabled the development
of distributed networks of sensor nodes capable of sensing and communicating using wireless
media. This enables to develop novel applications that change the way we interact with the world
around us.
In this thesis, we aim to develop a wireless sensor network application for dam safety monitoring
application where the sensor network encompasses heterogeneous types of sensors distributed in
different portion of a dam to gather data about the integrity of the dam. The sensor nodes are
organized in multi-hop cluster based tree to sample the different physical parameters of the dam
and route the reading to a central place for data management and visualization purpose. We have
implemented a dam safety monitoring application and its application specific routing protocol on
top of TinyOS operating system using nesC programming. We have also implemented data
management and visualization methods to present the data to the user in a user-friendly manner
and providing exact detail. For such purpose the following tools are developed: LiveWatch
which is a Java application for data logging, a web application to visualize the information on the
web, and SMS module for alarm notification. The application allows real-time collection and
processing of sensor data and presenting to the user through an appropriate interface.
We have evaluated the performance of our application through simulation using TOSSIM
simulator on MicaZ sensor nodes. Finally, we present some numerical results that demonstrate
the feasibility of our application and routing protocol. The experiment showed encouraging
results.
