Wireless sensor networks have been confirmed as a valuable asset to deploy in an increasing number of real-world business scenarios. The existence of several run-time reconfigurable component models for networked embedded systems facilitates this as they enable developers to build complete end-to-end systems composed of reusable building blocks. However, the integration of sensor networks with enterprise environments is not straightforward as it requires that several long-standing challenges related to data quality management and security be addressed. This paper advocates a high-level policy-based approach to more easily support the specification and enforcement of these non-functional requirements in existing component compositions for network embedded systems.
