“A Wireless Sensor Network (WSN) is composed of small, low cost and low energy consumption devices called sensors. Those sensors are deployed in a monitored area. They capture measurements related to the monitored phenomenon (temperature, humidity…) and send them through a multi-hop routing to a sink node that delivers them to a Base Station for use and decision making. WSN are used in several fields ranging from military applications to civilian ones, for security, home automation and health care… Up to now, most of the works focused on designing routing protocols to address energy consumption issue, fault tolerance and security. In this paper, we address the issue of secure management and interrogation of WSN through Internet mainly. In our work, we designed and implemented a generic approach based on Web Services that builds a standardized interface between a WSN and external networks and applications. Our approach uses a gateway that offers a synthesis of Web Services offered by the WSN assuring its interrogation and management. Furthermore, Authentication, Authorization and Accounting mechanism has been implemented to provide security services and a billing system for WSN interrogation. We designed our architecture as a generic framework. Then, we instantiated it for two use cases. Furthermore, we designed and implemented a Service Oriented routing protocol for WSN.”
