Next-generation sensor applications require system software and middleware that can be dynamically adapted to meet resource constraints on sensor nodes, as well as application-specific requirements. The reflective middleware model has emerged as a de facto standard to attain inspection and adaptation in dynamic software systems. However, prior reflective frameworks in the field of sensor networks come with some drawbacks, such as imposing high resource demands on sensor nodes, and lacking a precise design model ended up with a tailored programming model. In this paper, we consider reflection in sensornets from a programming perspective and propose an event-driven, component-based framework addressing both base-level and meta-level inspection concerns within reflective sensor software. To efficiently utilize the event-driven nature of sensornets, we propose a new meta-space model for adaptive sensor systems, named Notification. The proposed framework also makes the implementation of the base-level simpler and more efficient.
