Wireless sensor networks offer an entire new field open for research and development. These types of networks conceptually offer many exciting features including scalability, self-configuration, self-healing, multicast routing, and easy deployment. For these reasons, they are well suited for a wide range of applications in monitoring, control, surveillance, and distributed sensing among many others.
