Wireless Sensor Networks (WSNs) gone through rapid technology advances in recent years. It is an active research area at universities; also industrial applications are showing great potentials of future usage in everyday life. For software developers this is a completely new field, demanding new design requirements due to the resource constrains of sensors. This technology provides wide range of possible usages including disaster detection, health care and military applications. In my work, I am presenting a visionary project representing a flexible and secure usage of WSNs in natural environment.

The project is about a virtual fence system, aiming at preventing wild animals to enter a protected area. This is achieved by sensing movements with passive infrared motion detectors and injecting disturbing odour with a spraying device. In addition, I provide a management software to monitor and to control the sensors in the network. The design process is supported by simulations of the communication protocols used in the network.

The application will be capable of sensing movements and with distributed computing capability react to it accordingly. This architecture can be used at any related field: protecting an area where no static fence can be built or even to implement a smart building infrastructure. This flexibility holds the power of WSNs.
