For good reasons of interoperability and flexibility, wireless sensor networks (WSNs) are accessed by remote clients via service-oriented interfaces. At the same time, it can be useful to let clients deploy custom sensing and processing tasks directly on the sensor nodes. However, this raises the issue of how the remote client application can interact with such a task, in parallel to conventional access of the WSN. We propose an approach for adopting a unified web-based interface for both information flows. This way, WSN clients do not have to deal with different interface technologies. Moreover, the gateway of the WSN can handle both flows using the same protocol translation engine. The paper presents our design, briefly discusses a first prototype implementation, and shows an indicative usage example.
