Demo abstract: Discovering services in mobile, flexible and heterogeneous wireless sensor networks

Wireless sensor network applications (WSNs) are starting to enter into our daily life. Discovering sensor nodes and the services hosted by them is imperative to any large scale and flexible sensor network application. The heterogeneity and dynamics of wireless sensor networks and their applications are challenges for service discovery protocols. In this demonstration, we present a light-weight service discovery protocol (nanoSD) and its integration into a health care application with heterogeneous network architecture. NanoSD is a sensor network specific service discovery protocol that is specifically designed to be scalable and meet real WSN deployment challenges. Furthermore, it can easily be integrated with Web-service based backend systems with very minimal resource costs.
