The emerging reality of wireless sensor networks deployed as long-lived infrastructure mandates an approach to tailor developed arte-facts at run-time to avoid costly reprogramming. Support for dynamic concerns, such as adaptation, calibration or tuning of the functional and non-functional behavior by application users and infrastructure managers raises the need for ne-grained run-time customization. This paper presents a policy-based paradigm to realize the diverse concerns of the involved actors by enabling ne-tuning and optimization of the runtime environment. Integration of the policy paradigm into various main programming models is analyzed. A prototype implementation of the paradigm in the context of an event-component based wireless sensor network platform is evaluated on the SunSPOT sensor platform.
