Smart: Service Model for Integrating Wireless Sensor Networks and the Internet

Wireless sensor networks (WSNs) have received considerable attention in recent years as they have great potential for many distributed applications in different scenarios. Whatever the scenario, WSNs are actually connected to an external network, through which sensed information are passed to the Internet and control messages can reach the WSN. This paper presents Smart, a service model for integrating WSNs and the Internet at service level. Instead of integrating protocol stacks and/or mapping logical addresses, Smart allows the integration of Internet´s and WSN´s services by providing service interoperability. A communication infrastructure that implements the main components of Smart, along with a power consumption evaluation, is presented to validate the model.
