Recently, there is a growing IoT(Internet of Things) service using sensors for environmental monitoring and actuators for reacting to environmental changes. Sensor networks have provided us with facilities to collect information and track certain phenomena in the physical environment based on the region of interest. Sensor networks consist of a collection of sensor nodes and a sink node for many applications in different areas, including environmental surveillance, intelligent building, health monitoring, intelligent transportations, etc. In this paper, we present a sensor service provider for integration of heterogeneous large-scale sensor networks. This paper focuses on the design and implementation of the open sensor service provider for the integrated multiple sensor middleware in heterogeneous sensor networks. This provider has various heterogeneous sensor middleware, and each sensor middleware has a sensor networks. We design the sensor service provider using sequence diagram and state diagram, and implement it based on .Net framework. The sensor service provider has the service interface, the sensor content service manager, the sensor service manager, the sensing service manager, and the service controller, etc. The provider supports comprehensive to carry out the context acquisition and provisioning functionality.
